The Sea to Summit Ember is a backpacking quilt, not a sleeping bag: an open-backed down layer you strap to a sleeping pad. It uses RDS-certified 850+ fill-power goose down with a non-PFAS Ultra-Dry treatment, wrapped in a light 10D nylon shell with a non-PFAS DWR finish. The drawcord footbox closes for cold nights and opens for ventilation when it is warm. Straps attach it to a mat, and the QuiltLock system clips it to a Sea to Summit sleeping bag for extra warmth. It suits weight-conscious campers and hikers who sleep warm and want to shed the weight of a full bag. Against rival quilts it stands out on down quality and its bag-integration system; the trade-off is an open back that drafts in cold weather and thin 10D fabric that needs care.

The Ember Down Quilt is a multi-season quilt with a high warmth-to-weight ratio. It is insulated with RDS-certified, 850+ fillpower goose down treated with non-PFAS Ultra-Dry Down to stay drier in damp conditions. The shell is a light, breathable, recycled 10D nylon with a non-PFAS DWR finish to repel moisture. The 10D nylon liner is made for comfort.
In warm conditions, the quilt is easy to vent. As temperatures drop, the drawcord footbox helps hold in warmth.
Adjustable, removable straps secure the quilt to a sleeping mat or a sleeping bag. The integrated QuiltLock system lets you add it to a Sea to Summit sleeping bag for extra warmth in colder weather.
