Whether it’s cold glassing sessions, active time in camp, or even those dreaded midnight nature calls, the Sitka Gear Kelvin Aerolite 30 Sleeping Bag is a multifunctional layer designed to not only to keep you warm, but you keep you comfortable.

Featuring contoured shoulders and hood, functional armholes, and a center-front two-way zipper, you may think for a moment you’ve got on a Sitka Gear Jacket – but when you’re ready for bed after a long day of the elements, this sleeping bag is ready to keep you warm and dry. While similar to traditional down insulation in aesthetic and performance, the PrimaLoft® Gold Insulation with Cross Core™ technology outpaces tradition with warm-when-wet performance. The Sitka Gear Kelvin Aerolite 30 Sleeping Bag means no more freezing, damp nights under the stars – just toasty comfort, even in the wettest conditions!
