My pack is weight is low enough now that I am thinking of taking a more comfortable, but heavier sleeping pad with me (please forgive me UL gods!). I have pretty much decided that a full length neoair xlite is the way to go, but am a little bit concerned with durability as I will be going on extended trips using it (months). I will be careful with site selection etc, but to lessen this problem further I figured I would replace my heavy sit pad (2oz) with a very thin full length foam pad such as the granite gear thinlight 1/8" pad (about 2.5oz) or a Lawson Equipment insulite 1/8" (about 2.8oz cut down) to place under it. The advantages of this additional full length pad for me would be:
-protect underside of neoair
-provide a 0.75R rated backup should neoair fail and require patching
-groundsheet if using a tarp
-worry free sit pad/nap pad
-clean space to organise gear on the ground
-extra torso insulation (you never know!)
-backpadding
I would likely rig some sort of very minimal cord or velcro attachment system to keep the pad and neoair together nicely.
My question is does anyone know of some full length alternative to the thin foam pads which would do the same job of protecting the neoair and acting as a sit pad, but be lighter or better in some way? Maybe just an even thinner option. I imagine that a folded up 1/8" pad might be overkill really as a sit pad. Also I would be curious to know if anyone else uses the same setup as I am planning to go with (neoair+thin foam).
