850 fill power is where serious backpacking sleep systems begin. Premium down at the high end of outdoor specifications — warm enough for real cold, packable enough to not dominate your pack, and light enough that you won't resent carrying it.

 

What's Included:

•       850FP down fill — premium high-loft down at the upper tier of fill power specifications

•       Ultra-light shell construction — minimizes total bag weight while protecting the premium fill

•       Adult sizing across 18 variants — comprehensive matrix covering temperature ratings and sizes

•       Full mummy design — anatomical cut for maximum warmth efficiency

 

Perfect For:

Technical backpackers who benchmark fill power when comparing bags. Hikers who have upgraded from synthetic and want a genuine premium down experience. Anyone building a high-spec sleep system.
