Be The Jam

If you use a Thermarest outside without a groundsheet or other mechanism to keep it off the ground it will get punctures, lots of them.

It stuck me after a few goes of using this kit that it is unnecessarily complicated, sometimes there just isn't the time to boil a pan of water and allow it to cool over the recently fixed puncture. So I would go for days with a flat mattres, in the end I bought a bicycle puncture repair kit for a fraction of the price and fixed the hole in five minutes flat, easy. For long term repairs use the Thermarest repair kit, but if you are out and about I would recommend a bicycle puncture repair kit to keep you going.

Not relevant for jungle use, will be taking a hammock not sleeping on the ground.
