I've been using my Big Agnes system for a few years now with good to great results, BUT. I want better! The BA air mattress takes forever to inflate, is its worst problem, otherwise great packing size and average to good comfort sleeping on it. I've been wondering lately about another "Goose Down" bag for max warmth and a better quick inflating mattress that provides the same warmth as the BA mattress and maybe slightly softer too. I'm getting older and still camp vigorously throughout Winter months too. Anybody like me? I happen to see at REI a few days ago, some thicker self inflating types, but had no time to look and try'em out at the store. I have to go back. Therma Rest and others have always been so "bulky" to pack down to a reasonable size for the bike. Help? Randy"Polarbear"
