Rab Women's Alpine 400 Down Sleeping Bag (-5C)

The Alpine range is designed for mountain adventures, whether navigating the heights of the Alps or the depths of the Himalayas, on foot or by bike. Delivering an excellent warmth-to-weight ratio with a streamlined, low-bulk design, the Alpine 400 is perfect for springtime expeditions. It is insulated with 400g of 650FP duck down and encased in a wind-resistant Pertex® Quantum outer, complemented by a recycled nylon lining for a sustainable yet durable finish.

Crafted to enhance down insulation, the Alpine sleeping bag incorporates an intelligent construction. Trapezoidal boxwall baffles allow the down to loft fully, preventing cold spots and ensuring maximum warmth. The chevron baffle design further stabilises the down, evenly distributing insulation across the entire body. Thoughtfully designed to minimise heat loss, the bag features a 3D-shaped down collar that can be cinched snugly for enhanced thermal efficiency, along with a down-filled baffle along the zip to retain warmth.

Each Alpine sleeping bag is meticulously hand-filled in the UK, ensuring the down has never been compressed before use, preserving its loft and insulating properties. Designed with a narrow mummy fit, a women’s-specific shape, and an angled footbox, it minimises excess bulk while maintaining optimal comfort for a restful night’s sleep.
