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

Comfort −1.7 °C, limit −7.9 °C. That is late October and November camping in Ontario, and early winter with a good pad and a liner. Not a deep-winter bag.

The rectangular cut gives you room to turn and sleep on your side; the hood closes the heat leak that normally makes envelope bags colder than mummies. It is the bag for people who cannot sleep in a mummy but need real warmth.

Two lengths: M (1.07 kg, Grey) for most adults and L (1.31 kg, Black) for taller sleepers.

Spot-clean as a rule, and use a liner to keep the inside clean. It is not machine washable: wash rarely, with down detergent.

Same 700 g of 650FP down. The SP700 is a mummy: it packs a little smaller (Ø19 × 40 cm) and is rated warmer (comfort −7.3 °C against −1.7 °C) because there is less air to heat. The CW700 trades that for room to move and a hood you can throw back. Side sleepers and restless sleepers: CW700. Colder nights: SP700.
