Our take on the Sea to Summit Ember EB3 Quilt

The Ember EB3 is an ultralight down quilt rated to 45°F, built for backpackers who want warmth without a full sleeping bag. It uses 850+ fill-power RDS goose down in a 10D nylon shell with a non-PFC DWR finish, and weighs about 423 g in Regular. A drawcord footbox, removable straps and the QuiltLock system let you vent it on mild nights or seal it down when temperatures drop. Reviewers call it accurately rated, highly compressible and draft-free in the high 30s, though it is a quilt, not a bag, so it depends on a pad and straps to work well.

Pros

  • Straps and QuiltLock keep it attached to a pad or bag
  • Shell and liner fabrics feel light and packable
Cons

  • Straps take some fiddling to dial in
  • Not a standalone bag for cold sleepers
