Mummy Sleeping Bag — Premium Down Fill, Two Warmth Ratings

Stay warm, dry, and comfortable through cold nights outdoors. This mummy-style sleeping bag is filled with genuine white duck down for an exceptional warmth-to-weight ratio, wrapped in a durable, weather-resistant shell that packs down small enough to disappear in your pack.

Key Features:

Premium Duck Down Fill — 80/20 white duck down traps warmth naturally while staying remarkably light and compressible compared to synthetic fill.
Durable Weather-Resistant Shell — 380T nylon outer with a 300T polyester pongee inner lining stands up to repeated outdoor use while feeling soft against the skin.
High-Quality Zipper — Smooth-gliding, snag-resistant zipper for easy entry and exit, even in the dark.
Adjustable Hood Drawstring — Cinch the hood down to seal in warmth around your head and shoulders on the coldest nights.
Compression Stuff Sack Included — Compresses down to a compact, easy-to-carry bundle with buckled straps for quick packing.
