Ruby F. ★★★★★

Slept in this liner inside my 20-degree bag and woke up genuinely warm instead of shivering like usual. The Thermolite fabric feels silky against my skin, not clammy, which I didn't expect from a liner. Packs down smaller than my old fleece one too.

Jason ★★★★★

Took this on a 35°F night and the ceramic-infused fabric actually made a noticeable difference, I stayed warm without my bag feeling clammy. It packs down to about the size of a grapefruit too, so it barely took up room in my pack.

Eva C. ★★★★★

I was skeptical about how much a liner could actually add, but this one made a real difference on a 30-degree night. The Thermolite Pro fabric feels almost silky against my skin, and I didn't wake up clammy like I usually do.
