Why carry a full-size bag when you are not going to fill it? The Arapaho SL(short-length) is a fully-featured bag from campers on the shorter side. Control your climate with the Arapaho SL's innovative J-zipper, allowing you to unzip for ventilation and keeps the cold out with a thick baffle running the length of the zipper. In order to maximize warmth with minimal weight, the Arapaho SL utilizes a 60/40 insulation split from top to bottom. Combining the generous neck baffle with the form-fitting hood, you will easily snug yourself into a cozy cocoon. To ensure that this bag will last for many years, it comes with both a stuff sack and a mesh storage sack that allows the bag to dry and maintain loft properly while in storage. EN rated for a lower limit of 23F, the Arapaho SL will give you the needed comfort to maintain your temperature throughout Spring, Summer, and Fall.
