Alpha Direct Fleece 睡袋內襯

I was skeptical a liner could make that much difference, but this fleece layer genuinely boosts the warmth inside my bag without adding bulk. The fabric is soft against my skin on the first night, and it packs down small enough to stuff into a corner of my backpack.

The interior of my sleeping bag feels noticeably toastier with this liner tucked inside, and the fleece is soft enough that I actually look forward to sliding in after a long hike. It’s lightweight and packs down small, so it doesn’t add bulk to my pack at all.

Tossed it in my bag for a chilly campsite night and the fleece trapped heat way better than the bag alone ever did. It's soft enough that I actually skipped my usual pajama layer, and the extra warmth meant I didn't wake up shivering once.
