Are Tents Waterproof? Full Answer From A Real Expert (2021)

I’ve been sleeping in tents for over 30 years and I’ve experienced both good and bad tents as far as waterproofing goes. Nothing is worse than waking up in the middle of the night with a steady stream of water soaking your sleeping bag.

When camping, your tent is your home away from home. It protects you from the elements and gives you privacy if you are around other people.

One of the main things you need protection from is rain, so it’s important to know if tents are waterproof. So, are tents waterproof? The short answer is that many tents are waterproof but to differing degrees depending on design and the intended use.

How waterproof of a tent you need will depend on where you camp and the weather conditions. Not all camping trips are the same, so not all camping tents are the same.

We aim to cut through the noise and make it easier for you to make a smart decision when it comes to understanding if a tent is waterproof or not.

In this guide you will also learn how to waterproof your tent. In the end, you will have a true answer to the question “is my tent waterproof”.

But first things first.

Why are not all tents waterproof?

Later in the article, you will learn how to waterproof a tent. Tent waterproofing is quite an important skill to master.

A tent may not be waterproof for a few different reasons. It is more expensive to fully waterproof a tent so you will tend to find lower price tents are water resistant rather than fully waterproof. This depends on the hh rating (hydrostatic head). More on that later.

Secondly, it may be by design as the tent isn't designed for extreme weather. Often super light tents offer lower waterproof ratings as it is a tradeoff you get to have the lightest weight gear.

Finally, the tent may be designed for conditions such as snow or wind and doesn't need to withstand torrential downpours. So it's not waterproof.

Here’s what you need to know straight away.

All tents are a compromise. If you get the best weather protection, you will usually be paying a higher price.

Since most people aren't camping in monsoon season, it is still possible to get a tent at a reasonable price that will keep you dry during the conditions you are likely to encounter. In other scenarios, you need to waterproof your tent.

Moreover, if you happen to camp in areas where the rain is accompanied by wind, you have to make sure to stabilize your tent to the ground with special stakes for strong winds

What makes a good waterproof tent?

A combination of good design and materials are necessary to make a quality tent as waterproof as possible so that it could hold back a column of water at least 1000 mm in height.  

Think of an umbrella with a hole in it. The materials would block water (usually the correct measurement is column of water), but you will still get wet through the opening.

The fabric of the tent needs to be sealed well to withstand both rain and standing water (be waterproof). The tighter the weave and the thicker the fabric, the more waterproof it has the potential to be. In other words, it could withstand 

The downside is that thicker fabric adds weight, which isn't a problem when car camping but is a major negative when hiking or backpacking in the wilderness

All seams need to be sealed after it is stitched, as holes have been put through the fabric which will allow water through if not addressed. Even better would be if the seams are taped, but this adds weight so many companies just use a polyurethane coating to plug the hole made by the thread.

When it comes to design, the shape of the tent will play a big role in how waterproof it is. The steeper the sides, the easier water will flow off of it, thus making your tent less waterproof. Shallower angles can let water pool which increases the odds of a leak developing.

The shape of the waterproof fly affects the waterproofing low down on the tent. If the fly doesn't go low enough, you can get leaks from rain that is blown in or slashing.

A fly with vestibules that cover the doors of the tent will increase the weather resistance and give you extra storage space for gear.

Placement of the zippers and vents will have an effect on how waterproof the tent is as well. We suggest looking for tents with a storm flap that covers the zipper to keep it from leaking.

A waterproof top does little if the floor of the tent leaks so most tents are made with a floor that is impervious for water that wraps up the sides. The higher this bathtub construction goes, the more waterproof the tent will be.

Last but not least, and as mentioned before it's the hh rating, also known as the hydrostatic head rating that defines whether a tent is waterproof or just water-resistant.

And if it turns out your tent is not waterproof and you realize that when already camping in the rain, then your much needed sleeping bag better be.

What are waterproof tents made of?

Waterproof tents can be made from several different materials, but the most common for lightweight camping and backpacking tents is nylon or polyester fabric treated with silicon or polyurethane.

camping in the woods

The surface of the fabrics will also be coated with a durable water-repellent treatment (DWR) that causes water to bead and run off from the tent floor. This is the same treatment that waterproof breathable jackets are treated with.

Then the seams are sealed with polyurethane. This can be as a tape that is applied with heat or a liquid sealant.

Of course you can also waterproof your tent based on the type of materials it is made of. More on that later. We will also learn how to waterproof a tent the right way.

How to check if a tent is waterproof

Reputable companies will often give a rating of the waterproofness of their camping tents. This will be for the tent floor and rain fly.

You want to verify that they have treated it with a DWR coating to improve the beading and run off of rain water. When you treat it with DWR, make sure to use a damp cloth to remove any extra DWR.

Additionally, if you can check a summer tent out in the store, inspect the seams to see how they are sealed. Look at the zippers and see how they are covered to resist leaking. Don't hesitate to ask directly the tent manufacturer. 

And finally, it doesn't hurt to read reviews about how users have found them to stay dry in the real world.

Usually the manufacturer specifies the hh rating (hydrostatic head). This is a defining factor showing how waterproof a tent is. If it has drop cloth, which is quite durable, then most probably it has some waterproofing

Waterproofing ratings explained

Companies use the Hydrostatic Head test (hh rating) to rate the waterproofness of a fabric of their tents. The hydrostatic head rating is in millimeters of water the fabric can take before 3 drops of water are forced through.

Generally speaking, for tents, a hydrostatic head rating of 1000 mm is considered waterproof. For things like rain flies this is usually more than adequate but the floor of the tent will often be much higher. Anything else is just water repellent no matter if there's drop cloth or not.

The reason for this is that the floor is subject to much more abrasion and wear, so they treat it with more sealant to have it last longer.

If you are looking for light weight then the lower resistance rating under 2000 mm will do for the fly but be aware that you will have to treat it more gently.

This tends to be the case with most very light tents as you trade durability for a less load on your back.

Plus, the lower hh rating rating the tent has the more frequently you will have to retreat the waterproofing and seam sealing. For the latter, you can apply seam sealer. Most camping tents are made this way.

Difference between waterproof and water-resistant

That's also very important when it comes to tent waterproofing. The main difference is based on waterproof ratings. And that is dependent on the tent material do a certain degree. 

Waterproof tents will withstand long duration heavy rain. Whereas water resistant (or water repellent) ones will protect you from light sprinkles but not full on rainstorms .

Rain drops on tent

To know the difference, check the waterproof rating (hh rating) and the materials. If a company has waterproofed their tent, they will make it clear as this is a strong marketing point.

Look at the construction and see if the vestibule will block blowing rain. By the way the vestibule is a handy feature that also helps in keeping the bugs out of your tent.

In addition, check the seams to see if they are sealed. Also, the easiest way is to check the waterproof ratings.

When you need a waterproof tent

In the desert, when you are stargazing in your tent, for example, or other area with little risk of heavy rain, you can get away with a tent that isn't waterproof.

Check the waterproof ratings on your summer tent to know that for sure. For instance, does the floor have urethane coating?

The same goes in winter where you are going to experience snow rather than rain.

We recommend to have a durable water repellent coating for any moisture you encounter, but complete waterproofing is less of a concern. In any conditions where you can reasonably expect rain, especially thunderstorms which can be quite heavy, then a waterproof tent is a must.

On longer trips (thru-hikes, for example) that may see varying weather conditions, you have the option of not putting your tent fly on if you have a night with little chance of rain.

managing condensation 

In my many years in the outdoor business, one of the most common complaints I hear from people is that they got wet in their tent. Sometimes it happens even when it doesn't rain.

overnight backpacking

This is from condensation. Our bodies are constantly emitting moisture both in our breath and from our skin.

Especially when you’re camping with your date. Agree? When it is cold enough, this vapor condenses into liquid when it hits the inside wall of the tent.

Usually, it will run down the inside of the fly, but if the angle isn't steep enough or there is a lot of it, it can drip down on you and spoil your perfect camping trip.

Moreover, it isn't unusual to brush against the side of the tent which can send a stream of water down onto the urethane floor of the tent or on your sleeping bag.

This condensation build up can be especially bad when you have to have your tent all zipped up during stormy weather.

The combination of lack of ventilation combined with increased humidity in the air will make condensation almost a certainty.

If you don't want to get wet from the inside, you can do some things to minimize condensation in camping tents. Here are 4 actionable tips that work well.

  1. Choose a camping tent that has vents located high on the fly. Since the moisture coming off our bodies is warmer than the surrounding air, having the vents up high will allow a lot of that moisture to vent.
  2. Stake out the base of the rain fly to increase airflow. The cooler air coming in from ground level will create a convective current and help take the warm damp air out the vents.
  3. Unless you are expecting heavy rain, keep the door to the vestibule of your camping tent partially unzipped. If your tent has two doors, do this on both sides to create a cross current.
  4. Use a hanging candle lantern. A UCO Candle Lantern does wonders to dry out your tent. Burn the candle for 30 minutes before bed and upon waking in the morning to dry out your tent dramatically. Since you are burning a candle, even you contain it in a glass lantern, make sure you are careful lighting it and there is adequate ventilation.

Managing condensation is an important skill to master, as in fact is warming up your tent without electricity. Those skills will also greatly help in drying out your tent if it gets wet.

Are canvas tents waterproof?

Want to go on a camping trip and have a canvas tent?

Canvas is thick, tightly woven cotton that has been used in tent construction for a long time. On its own it is at best water resistant, but canvas can be treated to make it pretty waterproof (by applying seam sealer on the seals among other things).

Whether with wax, linseed oil or modern synthetic treatment, the fabric will need to be thoroughly coated and touched up regularly to maintain its waterproofing.

Only then you will have a waterproof tent. If it's still not, seal the seams, among other things that we will discuss later.

Are Coleman Tents Waterproof?

The answer here is an ambiguous yes and no. Not every Coleman tent is a waterproof tent. While that alone isn’t that helpful, it comes back to what we talked earlier about what makes a tent waterproof. It’s a combination of materials and design that work together to keep the water out.

The tent fabric is waterproof and the seams are sealed on all of their camping tents. However, they aren’t focused on making the lightest tents, so they can use a heavier duty fabric, which can maintain its waterproof properties longer than lighter weight options.

But many of the tents don’t have full vestibules covering the doors, which means the doors of the camping tent are exposed.

It won’t take much wind or rain to blow on to the zippers, which aren’t waterproof. And if you have the windows open for ventilation, rain can blown onto the bug netting.

This combination of features makes them suited for light showers but not torrential rainstorms with high winds. Want to seal the seams? You can but it won't make big difference. It's all about the tent fabric.

Are Ozark Tents Waterproof?

For campers and hikers on a budget, Walmart’s line of Ozark Trail tents is attractive. They are reasonably well made at a very low price, but are they waterproof?

The short answer for most of them is “no”. That makes them suitable for short overnight hiking trips with low chances of rain. But in our experience and that of many users, it is easily fixed by sealing the seams and spraying them down with a waterproofing spray or a seam sealer.

It may seem to be a pain to do that to a brand-new tent, but even when you factor in the price of the waterproofing, they still are only a fraction of the price of tents from Marmot or MSR.

At 21 lbs, it is too heavy to take backpacking, but if you want a place to hang out during all day rainstorms with enough space to cook in the vestibule, then look no further. It's perfect for hiking and camping with your kids.

How to Waterproof Your Tent 

Do you have a waterproof tent already?

If you are not sure if your current tent is waterproof, you can test this by setting it up in the backyard and create a steady rain shower with the garden hose or sprinkler. Are there any water droplets on the tent?

Plus you can easily waterproof your camping tent as we're about to explain. If it leaks inside from an extended spray, then you know you need to give it a waterproof treatment.

Here’s a fantastic video courtesy of REI:

Make note of where the leaks are to make sure you get those spots. It is best to do this before you go out rather than experience getting wet on the trail.

The seams are the most common place for your tent to leak since the stitching process pokes holes in the waterproof coating. The factory sealing is added after it is stitched and can peel off, so it needs to be refreshed on a semi-regular basis.

It's a good idea to redo the seam seal ever few years or whenever you notice a leak. Give it a nice polyurethane treatment. “Gear Aid Seam Grip” is the best option for the typical nylon bodied tent. You can find it in any hardware store. You just paint on the sealant on the inside of the rainfly with the supplied applicator. Another handy tip is to renew the DWR coating on your tent every few years. This helps water bead and run off, keeping the fabric from wetting out and potentially leaking. Grangers Tent plus Gear Repel spray will work well to waterproof the main body of your tent rainfly. Also, regularly apply seam sealer spray. Waterproofing your tent is not as tough as you might think. If you want to go one step further, use an alcohol tent sealant.

4 Proven Tips To Keep Your Tent Waterproof

Want to have a waterproof tent longer? Grab your seam tape and let's begin. This section is not only about waterproofing your tent but keeping it that way for long time.

Here’s some tried-and-true advice that I’ve found work really well based on years of experience with camping gear.

They will help you waterproof your quality camping tent. It's not all about the hh rating as you will see.

  • Pick a campsite that isn't in a low spot or in the path of water if it rains.
  • Use a ground sheet under your tent to protect the floor from abrasion and punctures.
  • Thoroughly dry out your tent before putting it away. Moisture can lead to the sealant peeling.
  • Inspect your tent regularly, looking at the seams and floor for any peeling or abrasion. If needed - treat with a seam sealer, also known as tent sealant. That will keep the waterproof coating intact for longer.


Now you have an answer to the question "are tents waterproof" or at leat maybe "is my tent waterproof". Since your waterproof tent is your home away from home, it is nice to know if it is waterproof. As we've seen, tents can be waterproof when made from the right materials and well designed.

Which Is The Best Waterproof Tent?


From Visually.

With your new knowledge, it should be easier for you to sort through the different tents available and get the one that will keep you dry while out in the wild. And you will be able to look after your tent to keep it waterproof for years to come.

Happy camping!
