Fever Ultra Ultralight Down Sleeping Bag

About the Y by Nordisk Fever Ultra

Formerly known as Yeti, after 15 years of close collaboration and joint ownership, Yeti and Nordisk have joined forces to become one united brand under Y by Nordisk. As the main part of the Yeti logo for years, the red Y is an established symbol of exceptional quality, animal welfare, and heritage of Yeti, the Down Specialist. Rest assured, your Y by Nordisk sleeping bag will continue to deliver the same standard of care and attention to detail, giving you the ultimate in performance.

When it comes to keeping weight to a minimum, the Fever Ultra down sleeping bag sets the bar. Part of the Y by Nordisk Addiction range, the Fever Ultra caters to those demanding the lightest, most technical equipment for high-mileage activities.

The Fever Ultra is crafted from Next To Nothing fabric. This super-light material uses an ultra-fine thread with a robust dense weave, delivering a breathable and water-resistant ripstop shell that regulates temperature and repels moisture.

Crystal Down 900+ fill insulation gives you the finest and most voluminous European goose down for comfort and warmth, with a stitched-through construction to keep it from shifting. Crystal Down offers a high level of insulation, with a compressible design that results in a compact pack size of just 18 x 11 cm. Crystal Down adheres to EDFA (European Down & Feather Association) ethical sourcing standards, to ensure each bird's welfare at every stage of production and supply.

The Fever Ultra features a flat hood adjustment, while loops let you hang the bag for airing after use. This compact sleeping bag also includes a compression sack for travel and a larger storage sack to avoid unnecessary down compression when not in use.

The Y by Nordisk Fever Ultra is the go-to warm-weather sleeping bag for fast-and-light outdoor adventures. With a packed weight of just 245 grams, the Fever Ultra delivers an optimised warmth-to-weight ratio essential for adventure races, climbing trips, and ultra-marathon running.
