Hammock Underquilts & Bivy Bags

Hammock Underquilts & Bivy Bags

This collection brings together hammock underquilts and bivy bags for lightweight camping, hammock systems, bushcraft and overnight trips. Underquilts insulate the underside of a hammock, while bivy bags add a compact protective outer layer around a sleeping setup.

Choose by sleep setup

• Hammock underquilts: designed to hang below a hammock and reduce heat loss from underneath. The range includes both down and synthetic models.
• Bivy bags: compact protection for minimalist overnight setups, emergency use or an additional layer around a sleeping system.
• Weight and insulation: compare fill type, total weight and manufacturer-stated temperature information on each product page, as construction and intended conditions vary by model.

For a complete hammock setup, browse hammocks. For a conventional trekking or camping sleep system, see our sleeping bags.
