Provides extra warmth

by Hackman, from Hong Kong Updated on May 18, 2019

The liner provides extra warmth and it's quite comfortable. It's a bit pricy indeed, that's why a star less. If you want to keep your pack small but you would also like to have extra warmth incase your sleeping bag is not warm enough, this liner is a good option.

Ehh ...

by Dave, Updated on March 13, 2022

Ive used this multiple times in varying temperatures and I honestly feel that for whatever reason I stay warmer just using my bag than having this liner. Iv had others use it was well and the max I would say it adds is maybe 5deg to a bag. I pretty much just use it as a liner to keep my bag clean. Expensive for that ... Id look elsewhere if you're looking to add warmth to a bag...

Warm, comfortable, a must have!

by Jeremy L., Verified Owner from OR, United States Updated on December 29, 2020

This liner is warm, comfortable, soft, and has plenty of space for free movement while camping. It is a must have for campers, especially if you're struggling to stay warm in the sleeping bag you already own.
