We recently saw where Outwell test their tents to ensure their designs are waterproof, which reminds us of some important points to choosing a tent that doesn’t leak. We run through 8 things to look for when buying a tent.
When you take the family camping and the weather turns wet, there may be that little nagging voice at the back of your mind saying “I hope the tent doesn’t leak!”.
We popped over to Denmark to where Outwell test their tent designs, blasting them with winds up to 9 or 10 on the Beaufort Scale (a very bad gale), and a deluge of rain. Six months of rain in twenty minutes in fact.
Seeing that much water come down on a tent really stresses what you should look for when buying a tent to make sure your choice is going to be waterproof.
Let’s run through some things that you can check to improve the chances of getting something that shelters you from the rain.
1. Check the seams of the tent
Where the tent material has been stitched together, check that the seams have been sealed.
From the inside of the tent you should see that the stitching has a waterproof coating.
2. Check the zips
Doorways are always a potential place for rain to come in.
Make sure the zips on the tent are protected from the rain. On a well designed tent you should find fabric and sometimes even a plastic cover to keep water way from the zip.
The cable entry may have protection similar to the zip on the main door, or may be under the ‘skirt’ of the tent, and so out of the rain.
If you just see a normal zip on the side of the tent, that that’s likely to be a source for leaks.
3. Check the Hydrostatic Head
The Hydrostatic Head is how waterproof the tent fabric is.
Basic tents may only have 2000 mm HH (Hydrostatic Head). This may be perfectly fine for mild conditions, but you may find that with a really heavy downpour, the water will seep through the weave of the fabric – but it would have to be a heavy downpour for it do so.
Some tents will have a much higher HH, giving you extra peace of mind. However, if the seams aren’t taped well, a tent with 8000 HH will still leak.
4. Check that there is a bathtub sewn-in groundsheet
A sewn-in groundsheet is one that is attached to the tent. A sewn-in groundsheet is not essential, but saves time when pitching.
The important thing is that it is a ‘bathtub’ groundsheet. This means that the sides of the ground sheet turn upwards at the side, minimising the risk of water coming into your tent.
Groudsheets should have a much higher Hydrostatic Head, such as 10000HH, and a thicker stronger material than the main tent fabric.
The points above are the things you should find on all family tents. However, there’s more things you could be looking for.
5. How good is the stitching?
Each stitch in the tent is a hole in the fabric, and so another potential source of leaks.
As mentioned above, these seams should be sealed, however tent designs can go further to minimise leaks, such as overlapping the material and reducing the amount of stitching that goes through the outer tent fabric.
Also check that the stitching uniform; not having a lot of stray material stitched or loose ends, that could be a sign that quality is not the best.
6. Is there a rain proof entrance?
Does the tent’s design allow you to get in and out of the tent without a lot of water pouring in as soon as you open the door?
There should be a shelter, or at the very minimum some form of ridge or gully, so that you can open the door in the rain without water pouring off the roof of the tent directly on you and creating an instant puddle on your tent floor.
7. Is there a waterproof treatment?
Some manufacturers will apply a waterproof treatment to their tents, in addition to a higher Hydrostatic Head in the material and well designed sealed seams.
This additional waterproofing helps water bead and run off the tent. The less time water is on the tent, the less chance it has of entering the tent.
8. Does the tent have a skirt?
OK, not literally a skirt, but some tents have some fabric that extends the side of the tent out and way from the groundsheet, and looks a bit like a skirt.
This material helps direct water away from the tent and away from the stitching with the groundsheet.
So there are a few things to look for when buying a tent so that you can choose one that will keep you dry.
As you would expect, the more design features you find will typically mean a higher price, but that’s not to say that more affordable tents don’t carry good waterproof features too. You just need to know what to look for 😉
