sleeping bag systems

The Kelvin Aerolite 30 Sleeping Bag is designed to be an extension of your SITKA clothing system and worn with additional layers for full-season performance. These systems have been independently tested in a lab to offer comfort at 10 and 20 degrees.


*Comfort testing was performed on an insulation ground pad with synthetic booties for the 20-degree system and down booties for the 10-degree system.*
