Thermarest

[The Survivor]

Snow in a month or twos time, I hope so! So its time to start training with full loaded winter kit...yippee!

Anyways, to the point. I am going up the mountains this weekend, and I am bringing my thermarest. Being Northern Ireland, it will almost definitely pour with rain, so the question is, can thermarests get wet!?

Such a long wind up to such a short question, oh well...lol

Cheers all,

Survivor

Short answer is yes if your tent or bivy bag leaks.

Will this matter to the thermarest, if it's a ccf then yes as it can absorb water. If it's a self inflating then no as it''ll be waterproof.

More important question is will your sleeping bag get wet if you're worried about your thermarest getting wet.

My sleeping bag will be in my bivvy bag, so hopefully it will not get wet.

its important to keep the inside of your thermarest dry.
what I do is after an outing, I leave my thermarest inflated and valve open in a dry place, valve pointing downward.
this way if there is any water inside, it will drain out.
I've had my thermarest for over 20 years, without problems.

You seen/tried the Thermarest Xtherm?

Its supposed to be really good for cold weather and wouldn't have any issues if it got wet.

Stick the thermarest in the bivi bag with you if there is room.

Closed cell foam is just that. The bubbles are sealed, if it was open, it would collapse beneath you like a sponge, and water would be the least of your worries.

Closed cell foam may get water on the surface but it won't soak it in. If you soak it in a bath and take it out and give it a shake, (outside, if you want to keep on good terms with other people in the house) it won't weigh any more once the surface water has gone.

I leave (or did when I used them) with the valve open and pointing up to allow moisture to evaporate. Unside down moisture will be retained to some degree or other.

All my thermarests I keep rolled up in there bag, I know I shouldn't but have never had any problems, oldest one is 14 years old now

The likes of the Thermarest Ridgerest is CCF as said it would have no support otherwise, however the self-inflating ones are open cell with an air/water tight cover. They have to be open cell to allow the ingress/egress of air, which is than sealed with a valve. And yup Rik's right, Cascade recommend storing them upright to allow any water vapour to evaporate.
