From what I've read on other sites, this particular bag from Marmot was made to be sold at exclusively at Dick's Sporting Goods stores.
I bought the Marmot Aspen 15* Explorer for $80. I haven't used it yet, but will be going to Alaska in August/September. The description says the bag will fit 6', but I am 6'4" and I still fit in the bag, just barely.
I chose the bag because it seemed to be the best quality for the money compared to the other Slumberjack bags that Dick's sells. It came with a nylon stuff sack and when packed is 18" x 8.5" across.
