Traditional comfort and value, with an anything but traditional design approach, the Trek Series sleeping bags are what we grab for globe-trotting adventures on a budget.

Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. The 3D side-wall baffle ensures that down can loft to the very edge of the bag, maximising insulation.

Lightweight fabrics reduce weight and packed bulk while the two-way #5 YKK full length side zip and separate foot zip, allows the bag to open out completely and double as a quilt. The foot zip is perfect for extra ventilation or to provide freedom of movement for your feet.

The panelled hood draws in tight when needed or lies flat for use in warmer weather. The oversized zipper draft tube uses anti-snag materials to prevent the zipper catching and the soft-touch 20D lining fabric is highly breathable yet also down proof. Completing the thoughtful design features of this classic down bag, a large internal security pocket is included, perfect for keeping valuables close or batteries warm.
