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. 

Kelvin Aerolite 30 Sleeping Bag Feature/Benefits

  • Synthetic PrimaLoft® Gold Insulation with Cross Core™ technology replicates the warmth and compressibility of down, but with the benefit of warm-when-wet performance
  • Lightweight insulation (35% recycled) is infused with silica aerogel, a nearly weightless material that’s composed of more than 95% air and acts as additional thermal insulation • 20-denier polyester face and backer
  • Durable water repellent finish resists precipitation and prevents face fabric from wetting out
  • ISO 23537, 30-degree F comfort rating; designed to be worn with other layers in your SITKA clothing system for colder conditions
  • Contoured shoulders and hood for a shaped and functional jacket-like fit when active
  • Centre-front two-way zipper
  • Armholes positioned for functional mobility; baffled draft tubes seal in heat
  • Stowed hook at bottom of bag connects to midlength interior loop; shortens the bag for walking 
  • Shaped footbox provides even warmth around your feet
  • Total weight: 1.1kg (38 oz.)

Sitka Gear Size Guide

Buy with confidence, we will happily swap sizes for you.

Sitka sizing is comparable to New Zealand and Australian sizes - so if you wear a large in a work shirt a large in Sitka will generally be the right fit too. 

Order the same size in base and outer layers, the outer layer in the same size is designed to fit over the layers that are likely to be worn underneath it.
