The Trek -1C Down Sleeping Bag by Sea to Summit is for the four-wheeled, adventure-driven travellers after lightweight but lofty comfort!

A Semi Rectangular Fit offers both a roomy and comfortable fit, ideal for car camping and shorter outdoor adventures. The lightweight, water-resistant, 20D recycled polyester shell and lining ensures durability beyond the backyard in various weather conditions and climates. Plus, RDS certified 650+ FILL Power goose down provides both comfort when unpacked and a compact pack down, treated with ULTRA-DRY down water-repellent to protect from moisture on the damper days off the grid.

A 3°C comfort rating and -1°C lower limit has it suitable for cold-weather camping, while the Free Flow Zip system features durable #5 full-length primary, half-length secondary, and footbox zippers, finished with zip plows, sliders, and a down-filled draft tube for easy, snatch-free use. Minimise cold spots thanks to vertical and horizontal chest baffles are present in both the lower-half and base, while box-wall baffles exist throughout the construction of bag. Plus, a fitted front collar draft helps to trap heat, while the hood offers a soft-touch adjustment and generous room for a regular-sized Sea to Summit pillow.
