The Alto is the ultimate choice for ultralight adventures and a central part of the famous Nordisk 2 kg camp. Crafting this amazing insulation-wonder is possible due to a fantastic combination of premium Crystal Down® and the ultralight 7-denier Next to Nothing® fabric. With a weight of just 120 grams (size S) Alto still offers full functionality in terms of insulation, breatability and packability. Optimal when in need of an extra insulation layer but you require ultra-small pack size and the lowest weight possible. Nothing can match this one on a heat to weight ratio.
