Hi. New to the forum. I'm shopping for a sleeping pad to use with my Big Anges Lost Ranger +15 bag (no insulation on the bottom; 20"x72" rectangular pad slides into a sleeve). Looking for something REALLY comfortable and warm for my 60-something-year-old bones for a backpacking trip in the Rockies this summer (a week above 10,000 feet). Weight and small packing size are also major considerations. I've narrowed it down to the Exped SynMat UL 7 and the Big Anges Q-Core SL, which seem rather similar in most respects, with the Exped packing smaller and the BA being warmer. The cost is right up there, but I have a $100 credit with REI to soften the blow, and I've also noticed both pads selling on eBay.
So, which should I choose? Or should I be looking at others?
