The Fever Ultra is Yeti's lightest bag at this temperature rating. Using the most premium materials available Yeti have produced a great bag for fast and light adventures.
Fever Ultra is the ultimate choice for an ultra-lightweight sleeping bag. Fever Ultra has a weight of only 280 grams and an extreme temperature of down to minus -2 Celsius. The weight is kept to an absolute minimum by using the lightest down proof fabric available, while insulation is kept at its highest using premium European goose down. A sleeping bag popular among participants in the world's toughest ultra runs.
Nordisk's Fever Ultra Down Sleeping Bag is perfectly suited to fast and light adventures. Weighing in at well under 300g Yeti have still managed to fill this bag with 100g of premium 950+ fill power down. With lightweight, down proof fabrics you still get a soft, comfortable feel and it has an impressive weight to warmth ratio. This bag is obviously best suited to summer conditions, warmer weather and hot sleepers but with a few spare layer on you can get more use out of this bag.
The choice of materials and slim fit result in an impressively small packsize. This is a great sleeping bag for adventure racing, mountain marathons and fast and light adventures in mild conditions.
