Zpacks 10f Solo Quilt

Zpacks built the 10f Solo Quilt as a 4-season, cold-capable top quilt around 900 fill power US-standard goose down, treated with a hydrophobic finish and packed into a box-baffle construction with vertical baffle orientation to limit cold spots. At 577g total with 441g of fill, and a -12°C limit temperature (-29°C extreme), it delivers a lot of warmth for the weight, reflected in its low weight-per-degree figure. The 7-denier Ventum ripstop nylon shell and liner keep the packed size to roughly 30x13cm, small enough to disappear inside a frameless pack. Pad attachment loops replace a full zipper, and instead of a stuff sack it ships with a storage sack, plus a separate DCF dry bag for the trail. RDS-certified down and a PFC-free finish tick sustainability boxes without adding weight. The catch is sizing: this listing is the short length, rated to a 167cm max user height, so taller hikers need to check Zpacks' longer options. Overall it targets ultralight thru-hikers and winter-adjacent trips where every gram in the sleep system counts.
