NEMO Kayu™ Men's Down Mummy Sleeping Bag 30

The NEMO Kayu 30 is the lighter, warmer-weather sibling in the Kayu line — comfort rated to 5°C and limit -1°C under EN ISO 23537, making it a typical three-season bag for summer alpine nights and non-winter lowland trekking. Its 290 g of 800 fill-power hydrophobic goose down keeps total weight to just 785 g. Materials match the colder models in the line: 20D nylon ripstop shell with DWR treatment and a 30D nylon taffeta liner. The contoured hood, draft collar, and draft tube carry over from the warmer bags, with the addition of footbox ventilation to dump heat on milder nights. A full-length left-side zipper still allows two bags to be coupled together. It compresses to 27 × 16 cm and comes with both a stuff sack and a storage sack. Given its low weight and small packed size, the Kayu 30 suits lightweight multi-day trips where sub-freezing nights aren't expected.
