Reactor 刷毛睡袋內襯 (近乎全新)

Took this on a shoulder-season trip where temps dipped near freezing, and the grid-pattern weave held warmth way better than my old basic liner. The hollow-core fibers feel surprisingly light for how much heat they trap, and the used condition was honestly flawless.

The grid pattern of the Thermolite Pro fibres actually traps heat noticeably better than my old flat liner, and it packs down small enough to stuff into the bottom of my bag without adding bulk. Woke up warm on a 40-degree night where I'd usually be shivering.

The grid-pattern weave actually makes a noticeable difference—I stayed toasty on a 30°F night without the bulk of a second bag. It packs down small enough to shove into the foot of my pack, and the hollow-core fibers feel genuinely warm against the skin.
