>"I did notice a thread the other day for something other than the Neo air.. i think people where buying it on Amazon for like $30-$60?"
Prob. POE Peak Elite AC.
For 3 seasons, I like my 3/4 length Thermarest Prolite. 10.7 oz, R 2.2, low volume deflated. Pretty tough and lifetime warranty. ~$80 full retail. Before that, I used the earlier generation Prolite, which weighed 3 oz more. Pad is about 1" thick, which is comfy enough for me.
Cheaper and lighter is a cut down blue CCF pad (or Ridgerest or Z-rest). Much higher volume, tho. If I remember right, you're trying to get all your gear for 2-3 days in a 22 liter pack, so CCF is prob. out.
For the price, weight and warmth, I'd be interested in trying a full-length Peak Elite one of these days. For me, a Neo-Air is luxury I don't need, no other added benefit over what I have, and money I'd rather spend elsewhere.
My 2 cents, as they say.
