Description
The Naturehike CW400 Down Ultralight Sleeping Bag is for trekkers who want warmth without weight. It holds about 400 g of white duck down and weighs about 0.9 kg in total, with a comfort rating of 5°C for the 650 fill-power version. The hybrid shape is snug like a mummy bag at the top and roomier at the feet. The shell and lining are 20D 400T nylon, light and water-resistant, with a YKK two-way zip. It measures about 220 × 85 cm and packs to roughly 35 × 18 × 18 cm, much smaller than a synthetic bag. For multi-day treks in the Himalayas, Sahyadri overnights and lightweight bikepacking, the CW400 saves weight and pack space.

Frequently Asked Questions
Is the CW400 warm enough for winter treks?
It is rated 5°C comfort. For sub-zero winter treks, a warmer bag such as the Mujin MJ600 is safer.
Down or synthetic: which should I buy?
Down is lighter and packs smaller; synthetic handles damp better and costs less.
How should I store it?
Store it loosely, not compressed, and dry it fully after each trip.
