    Comfort, versatility, and value all in one bag! The Sea To Summit Trek Tkll -8°c Sleeping Bag provides traditional comfort at an affordable price, with an anything-but-traditional design approach. 

    The vertical baffles over the chest section ensure the down insulation cannot escape or shift outside of the bag while you're asleep, creating cold spots during the night. 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 length side zip and separate foot zip allow the bag to open out completely and double as a quilt. The foot zip is great for extra ventilation or to give your feet extra movement. 

    The 3D side-wall baffle ensures that down can loft to the very edge of the bag, maximizing insulation, while the paneled 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, while the soft-touch 20D lining fabric is highly breathable yet also down proof. 

    The Trek™ Series sleeping bags are the go-to bag for globe-trotting adventurers on a budget! 


    Completing the thoughtful design features of this classic down bag, Sea to Summit have included a large internal security pocket, perfect for keeping valuables.
