絲質混紡睡袋內襯

I was skeptical about the infrared yarn thing, but this liner genuinely feels warmer than my old cotton one. The silk blend is soft against my skin and it packs down to almost nothing in my pack.

Bought this for a cold-weather trip and the Thermolite Pro yarns really do add noticeable warmth without making me sweat. It packs down to the size of a soda can, which sold me since my pack was already stuffed.

Stayed surprisingly warm in this thing even on a 40-degree night, which I didn't expect from a liner. The silk blend feels soft against my skin instead of that clammy nylon feel, and the Thermolite yarns really do seem to add a few degrees of warmth. Packs down tiny too, which sold me.
