QDM-400-Black Pink Down Sleeping Bag 1.61 lb 45-61°F

Ultralight three-season down bag

The QDM-400-Black Pink is a mummy-style sleeping bag built for solo backpackers and hikers who prioritise minimal pack weight. It uses 14.11 oz of 600 fill-power duck down to deliver warmth in a 1.61 lb package rated for comfort between 45 and 61 °F. The tapered cut reduces dead air space while a wide trapezoidal foot box prevents the cramped feeling common in traditional mummy bags. An internal pocket keeps small essentials like a phone or keys within reach.

Tear-resistant nylon shell and liner

Both outer and inner fabrics are 400T nylon chosen for rip resistance and to stop down migration through the weave. A full-length zipper allows the bag to be opened flat or zipped to a matching left-hand unit to create a two-person quilt for couples. The included compression sack shrinks the bag to 10.63 by 5.91 inches, roughly half the volume of a synthetic-fill equivalent, making it simple to stuff into a daypack or strapped to a frame. Users should air the bag for three to four hours after unpacking to restore full loft.

Warmth retention with minimal bulk

The 600 fill-power down traps heat efficiently while staying highly compressible, so the bag remains light without sacrificing insulation at its rated temperatures. The mummy hood and draft tube along the zipper limit convective heat loss on breezy nights. Because the fill is natural down, it breathes well and manages moisture during active use, reducing clamminess compared with synthetic fills. The construction avoids cold spots through consistent baffle distribution, delivering steady warmth from 36 °F limit up to the 61 °F comfort ceiling.
