Sitka Kelvin Aerolite 30 Sleeping Bag - Sub-Alpine

This bag never sleeps. A wearable sleeping bag for multi-use warmth.

After years of designing clothing systems that protect in extreme conditions, Sitka Gear turned their attention to the sleeping bag as your final layer of mobile warmth. Viewed as an extension of your clothing system, the Kelvin Aerolite 30 Sleeping Bag does a lot more than sleep. Its multifunctional design keeps you warm well after sunrise. After all, why should your sleeping bag only work for you at night? 

The Kelvin Aerolite 30 Sleeping Bag is a multifunctional layer for active time in camp, cold glassing sessions or dreaded midnight nature calls. Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the aesthetics and performance of down insulation, but with warm-when-wet performance. Featuring a 30-degree F (-1 degree C) warmth rating, it’s designed to be an extension of your SITKA clothing systems for full-season performance, even in the wettest conditions. Jacket-like features include zippered, functional armholes; contoured shoulders and hood, and a centre-front two-way zipper.
