Sea To Summit Trek II Down -8° Sleeping Bag Long Blue Denim Navy

Traditional comfort and value, with an anything but traditional design approach, the Sea To Summit Trek Series sleeping bags are what to 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.

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 3D side-wall baffle ensures that down can loft to the very edge of the bag, maximising insulation, while 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.
