The Conundrum -10 950 is Enlightened Equipment's warmest quilt built on the hybrid platform: a sewn-closed footbox paired with a 3/4-length side zipper that lets it close into a sleeping-bag-like shape rather than staying fully open like a standard top quilt. It uses 950 fill-power goose down — RDS certified — at 676 g of fill for a 955 g total weight, and carries a -10°F (-23°C) rating aimed squarely at winter expedition use.
Compared to lower fill-power alternatives, the 950-fill down here reaches a higher warmth-to-weight ratio, meaning less down mass is needed to hit the same temperature target — one reason this version comes in noticeably lighter than an 850-fill quilt at the same rating. A draft collar and draft tube add sealed protection around the zipper and shoulder area, addressing the main heat-loss weak point of any quilt with an opening.
This listing is cut in EE's Regular size, rated to a 183 cm maximum user height, so it will not suit taller sleepers. A stuff sack and storage sack are both included.
