I mostly carry my switchback, I had an ultralight inflatable, but it didn't hold up. I have an ancient 3/4 therma-rest guidelite that I carry some times in the summer, but it's half a pound heavier than my switchback. Mostly I just try to hike hard enough that I'm tired enough to sleep where ever. I agree with the poster who mentioned shelters, the switchback is way better on the ground than a shelter floor.

We use Thermarests or their equivalent from like REI. ¾ sized ones to save some bulk.

I use my full length R4 self-inflating pad all year long. For sub-freezing temps I add a 3/4 length R3.2. I use a 20oz "emergency blanket" (tarp with mylar side) as a ground sheet for bivouac, tent footprint, and emergency shelter.

When I was younger I got a 3/4 length therma rest sleeping pad for a backpacking trip to save on weight. It worked it was fine for the trip, I'm really short anyway and didn't notice. 12 years later I used it again and let my bf use the full body one because he had never gone real camping before. Oh man, I can sleep through a lot and pretty easily. That was the most uncomfortable I've been in years sleeping on the ground. Get one. You'll regret it.

I'll hype my Thermarest self inflating pad. I think it's 3/4". It was expensive when I got it, but I've used it many times over 30 years and it's still working well. It could be more comfortable. But I carry it on a pack. It's worlds better than not having it.

I've had a self inflating Thermarest for about 30 years. I never camp without it and it still works great. Some years ago I had a canvas cover made for it. It's a disguise for when I go Civil War reenacting, and offers a layer of protection against brogans.

The Thermarest self inflating is rubbish. Just some thin foam that helps to expand and suck air into the pad. But you still need to inflate it further. My exped mat is filled in a minute with the pump sack.

I use Thermarest pads, have for years, I store them deflated and rolled up, the self inflating feature works fine for me but it takes a little time, just unroll them as soon as you get to the campsite and leave the valve open until you’re ready to sleep, it may need a little topping up by blowing but not much

I've used a Thermarest self-inflating pad as my main bed for almost 3 years now and it's still going strong - the key is to get a quality one and occasionaly rotate it to distribute wear, plus putting it on some kind of platform rather than directly on floor helps prevent moisture issues that can degrade the matterial over time.

These are self-inflating pads - just open the valve and they'll mostly inflate on thier own, then you only need a few breaths to top it off!
