Trek Down Sleeping Bag

If you've ever wished for a less-constrictive sleeping bag that keeps you comfortable in a variety of cool-to-warm conditions, the Trek may become your go-to bag.

The Free-Flow Zip system allows you to open the bag sequentially for ventilation up to the point where it is opened flat as a quilt - you can even secure the snaps around your shoulders, open the footbox zipper and 'wear' the Trek around camp.

650+ fillpower duck down with a non-PFAS Ultra-Dry Down treatment keep you insulated in damper conditions. Slip an Aeros Pillow into the hood and enjoy a great night's sleep - wherever your travels take you.

Customer Reviews (4.4 / 5 · 5 reviews)

Eli S. ★★★★★

I was expecting the usual mummy-bag squeeze, but the roomier cut actually lets me shift

Lucy H. ★★★★★

Wore this on a two-night trip where temps swung from warm to chilly, and the Free-Flow zip let me vent heat without wrestling the whole bag. Down lofts up nicely and packs smaller than my old synthetic.

Harper K. ★★★★★

Slept in this down to about 35 degrees and stayed toasty without feeling like I was zipped into a coffin. The less-constrictive cut means I can actually curl up on my side, which I've never managed in a mummy bag before.
