Rab Alpine 400 Down Sleeping Bag

An ultralight and compact down sleeping bag designed for ultimate comfort during spring and summer.

Ultralight backpackers and space-saving campers will love the Alpine 400 by Rab. Made from durable materials and hand-filled in the UK with 400 grams of responsibly sourced duck down, the sleeping bag provides all the warmth and comfort you need during spring and summer expeditions.

A Trapezoid boxwall baffle construction maximises the down’s ability to loft while reducing cold spots for comfortable warmth throughout. It uses a narrow mummy-shaped fit and angled footbox to ensure the pack size remains as light and compact as possible.

When storing at home, use the provided cotton sack which will prevent the down from remaining tightly compressed for long periods and extend the performance of the sleeping bag.
