I'm going through my sleep system and trying to get lighter and more efficient. I'm trying to get set for a low of around 20 degrees, but I'll rarely see temps below thirty in my area. The Nemo Vector insulated pad is light for the large size, has its own air pump, and is rated around my desired temp range. I've also read that it's quieter than the NeoAir Xtherm right now it's on clearance in a few stores for under $100. I don't want to buy junk, but $100 is around what I have to spend. I've read good things about Nemo, and like the idea of having both a pump and a valve I can blow the pad up by mouth. The large size is around 20 oz, which is fine if this pad will get me down to 20-25 degrees without too much misery. I'm using a Sierra designs 20 degree Backcountry quilt and have a patrol bag and sleeping bag liners I can supplement with if necessary. 90% of my backpacking is above forty degrees at night. Does anyone have any thoughts or suggestions? I'm thinking I'll be in decent shape but wanted to check and see if there were any horror stories about this pad first. My wife and I haven't had great luck with Klymit so wanted to try something else. Thanks for your insight.
