Y By Nordisk 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 minimising weight, 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 also 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 305 grams, the Fever Ultra delivers an optimised warmth-to-weight ratio essential for adventure races, climbing trips, and ultra-marathon running.
