Should I trust this pad for sleeping on wooden planks in AT shelters for months on end? I need comfort, insulation and weight-saving, but packed in a durable shell, is this it?

I agree, one should never go out with an inflatable pad without a repair kit. That is simply asking for trouble. however, no need to bring the entire kit, but instead, just take the items that you need in the repair kit and it will hardly weigh a thing. That said, if you are going to be out for months on end (or really even for a single night) I would imagine that you have a shelter of some sort, and maybe a ground sheet to go with it? The Gossamer Gear Polycro ground sheets can be cut down to weigh less than an oz and still be a little bigger than the size of your pad. Just simply use your ground sheet inside the shelter under the pad. Also, it is always good practice to treat any air pad as just that. Before laying it down, check the area for sharp objects. I understand that sometimes accidents happen, but a quick rub over with the hand should tell you something about the spot. Good luck!

Good points, Wee. Thanks for the advice.

I have a neo-air and love it for comfort. If you're going to be out for months on end, you're taking a risk by only bringing this pad - there's always a chance the inflatables will puncture. That said, I'd probably still use it (the good night's sleep is worth it for my temperamental back) and just be careful to put some sort of barrier between it and any wood planks that might have splinters. I have two 45# pups who do walk over these in the tent - their nails have never punctured one yet…so that's all I’m basing my comment on. You're def going to find people falling on both sides of this issue. Perhaps just consider bringing a tiny repair kit if you'll have time and the ability to find and fix punctures along the way.
