Naturehike Cicada Wing CW700 Down Envelope Sleeping Bag - With Hood (2026)

The Cicada Wing CW700 is a hooded envelope-shaped down bag rated to a −1.7 °C comfort temperature — a three-season bag with more room to move than a mummy cut, available in two lengths.

Envelope cut with a hood

• The rectangular shape gives you room to shift position, which is the main reason people who sleep badly in mummy bags switch to this shape.
• The hood closes the biggest heat leak an envelope bag normally has, so you keep most of the comfort without giving up the warmth.
• 650FP down, 700 g of fill: comfort −1.7 °C, limit −7.9 °C, extreme −26.2 °C. Extreme is a survival figure, not a sleeping figure.

Weight and packing

• 1.31 kg, packing to Ø20 × 42 cm in M or 22 × 42 cm in L.

Care

• Not machine washable — hand wash only.
• Down loses loft if it's stored compressed, so keep it loose between trips rather than in the stuff sack.
