Hm. Curious, if I were to get that sea to summit comp. bag, what size would I need for this bag?
Also, what do the bx and the S1 mean in the title?
Jason, I believe it means that it is a 1 season bag (S1) and it has a stuff sack but no storage sack. It is shipped in a box instead and thus the BX designation. Someone please correct me if I am mistaken.
