Our Alpine range is designed for the mountains, whether you're at high altitude in the Alps or in the heart of the Himalayas, on foot or on two wheels. With its excellent warmth-to-weight ratio and compact size, theAlpine 400 is the ideal sleeping bag for springtime mountain adventures. It is stuffed with 400g of 650 cuin duck down, covered on the outside with windproof Pertex® Quantum and on the inside with a recycled nylon lining.

The Alpine sleeping bag is based on an intelligent design that optimizes the performance of down. The trapezoidal divider allows the down to expand fully, eliminating cold spots and optimizing warmth. Herringbone partitioning enhances the stability of the down, which is distributed evenly over the body. What's more, the Alpine sleeping bag's openings have been designed to reduce heat loss, with a 3D down collar that can be tightened to retain heat, and an insulating down flap at the zipper to prevent heat from escaping. Featuring a narrow sarcophagus cut and an angled foot compartment, the Alpine sleeping bag has been designed to reduce bulk and unnecessary weight while ensuring a comfortable night's sleep.

Hand-filled in the UK, tous our down sleeping bags benefit from never having been compressed before use, retaining their warmth and loft.
