Zpacks 20F Classic.
900-fill down in a 15 oz quilt from the makers of the Duplex Pro tent. Ultra-minimal construction for gram-conscious thru-hikers.
The Verdict.
Gavler Meta-Score
“The gram-counter's endgame quilt. 15 oz at 20°F is unmatched. Requires experience and technique to use effectively — not a starter quilt. The right pick for experienced UL thru-hikers.”
