Sea to Summit Trek Down Sleeping Bag -9°C

Experience spacious comfort and superior warmth with the Sea to Summit Trek Down Sleeping Bag (-9°C)—designed for campers and travellers who want more room to move without sacrificing insulation. With its semi-rectangular fit, this bag provides a less-constrictive sleeping experience, perfect for those who prefer a bit more space while sleeping under the stars.

Featuring RDS-certified, 650+ fill-power duck down insulation, the Ultra-Dry Down treatment keeps the insulation drier in damp conditions, maintaining loft and warmth in unpredictable weather. The recycled 20D polyester shell with a non-PFAS DWR finish helps block wind and moisture, while the soft polyester liner delivers next-to-skin comfort for a great night's sleep.

The Free-Flow Zip System provides versatile temperature control, allowing you to open the bag in stages for ventilation, or completely flatten it into a quilt for warm nights. You can even secure the snaps around your shoulders, unzip the footbox, and wear it around camp like an insulated wrap—a game-changer for cold mornings.

With a tapered rectangular shape and a max user height of 185cm, the Sea to Summit Trek Down Sleeping Bag (-9°C) is perfect for cold-weather camping, backpacking, and extended travel. Zip up, stay warm, and sleep in comfort—wherever adventure takes you!
