Down Sleeping Bags

Using high lofting responsibly sourced ULTRA-DRY Down, our down sleeping bags are ultralight, compact, and offer superior warmth. Find the right down sleeping bag for your next adventure.



A favourite among campers and hikers, Sea to Summit’s range of award-winning lightweight down sleeping bags offer the best warmth-to-packability ratio, comfort, and longevity.

Every Sea to Summit down sleeping bag features premium high-lofting, RDS certified ULTRA-DRY Down. This permanent nano-level water-repellent treatment applied to our down protects it from external moisture and condensation from inside the bag. This ensures our sleeping bags are not only lightweight but high performing in both dry and damp conditions.

100% of the down used in our compact sleeping bags and quilts is independently certified to the Responsible Down Standard (RDS). The RDS certifies down against animal welfare requirements and tracks it from the source to the final product. The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is certified to the RDS.


Constructed using high-quality fabrics, each of our lightweight and compact down sleeping bags have been specially engineered and shaped for the designed end use. This means maximum comfort and warmth without sacrificing versatility or packability. Our purposefully constructed sleeping bag baffles keeps the down insulation exactly where you need it, preventing cold spots and ensuring you stay warm during the night.

Whether you’re looking for a technical minimalist ultralight down sleeping bag for fast and light activities, like bikepacking and thru-hiking, where space and weight are a premium, or a down sleeping bag that’s versatile enough for multi-season adventures, explore our range of exceptionally lightweight, warm and compact down sleeping bags now.
