Parsec™ 0F/-18C Down Sleeping Bag

The 900-fill down is incredibly warm for its weight—I actually slept comfortably in 0°F weather without any extra layers. The bag compresses small enough to fit in my pack with room to spare.

I've never owned a bag this light that actually holds heat — the 900-fill down is no joke, and I stayed toasty through a night that dipped well below freezing. Packs down small enough to strap on the outside of my pack without throwing off my balance.

Took this down to about 15F on a backpacking trip and stayed toasty in just a base layer. The 900-fill down really does pack down small, which my shoulders appreciated on the hike in.
