Insulated with duck down and rated to -18°C, this roomy sleeping bag offers less restriction and is suited to 4 season hunts in the Victorian Alps and New Zealand conditions.

Sea To Summit's Trek range offers solid upgrades to previous models focused around increased sizing and flexible fill options. 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.
