Rab Ascent Pro 800 Sleeping Bag

Warm and protective, the Ascent Pro 800 has been designed for the harsh winter conditions of Scotland and Scandinavia. It features a generously wide fit, allowing the weary mountain adventurer to enjoy a restful and comfortable night’s sleep. Insulated with 800g of 650FP duck down, it is an exceptionally warm sleeping bag, offering ample space to wear additional, bulkier layers inside when tackling seriously cold environments.

Equipped with a Pertex® Quantum Pro outer that resists both wind and water, along with hydrophobic duck down insulation, it performs superbly in windy, damp, and condensation-heavy conditions, making it an excellent choice for snow holing or bivouacking on exposed ledges. With the ability to withstand plummeting temperatures, it serves as a superb all-round winter sleeping bag for adventurous souls. Crafted with trapezoid-shaped, boxwall baffles that fit neatly together, the construction encourages the down to fully loft, maximising warmth and minimising cold spots. Hand-filled in the UK, every down sleeping bag benefits from the fact that the down has never been compressed prior to use, thereby preserving its loft and insulating power.

The Ascent Pro features a ¾ length main zip with a down-filled internal baffle and a 3D-shaped neck baffle, both engineered to minimise heat loss. A zipped internal pocket is included, perfect for keeping a headlamp within easy reach during the night, and thanks to the angled foot box, sleepers can enjoy a naturally relaxed sleeping posture. Those travelling with a companion or simply seeking extra room can opt for a left and right zip combination to join two bags together.
