Underquilts
Jacks R Better invented the hammock underquilt in 2004 — still the warmest, most reliable way to beat the cold air beneath you, with no crushed insulation and no cold spots. Our underquilts hang below your hammock to trap a warm layer of air. The dedicated line uses 850FP down behind our wind-resistant Ion 1.1 shell, with 1000FP down / 10D (0.67 oz/yd²) ultralight multi-function options too. 20° to 0°, hand-sewn in Pennsylvania.
