NEMO Riff™ Men's Down Sleeping Bag 30

The NEMO Riff 30 is the warmer counterpart in the Spoon-shaped line, pairing a mummy cut with extra knee room aimed at side sleepers. A 4°C comfort rating and -1°C limit (EN ISO 23537) place it firmly in three-season territory — summer alpine nights and milder spring or fall trips. Filled with 280 g of 800 fill-power hydrophobic, RDS-certified duck down, it weighs 825 g total. Both shell and liner are 100% recycled polyester ripstop with C0 DWR treatment — a water-repellent finish free of the fluorinated chemicals used in older coatings. A three-quarter-length, two-way zipper on the left side allows venting or coupling two bags together, while a draft collar, draft tube, and footbox ventilation help manage warmth on milder nights. An internal pocket holds small items like a headlamp or phone. The Riff 30 packs to 27 × 19 cm, and its roomier cut combined with relatively low weight makes it a solid pick for side sleepers who want to shed weight compared to the colder Riff 15.
