A warm four-season down sleeping bag, the Rab Ascent 900 Regular has you ready for winter camping and general mountain use. The generous mummy shape and wide footbox enable a relaxed sleeping posture, with enough room to wear extra layers when temperatures drop.
Consciously made, the Ascent 900 features a recycled Pertex Quantum outer, recycled nylon lining, and 900g of 650 fill responsibly sourced hydrophobic duck down. The trapezoid box wall baffles stack together, letting the insulation loft while minimising cold spots. An ergonomic hood plus baffles around the neck and along the ¾ length zip help seal in the heat. Extra features include an internal pocket that can fit a phone or head torch, a stuff sack, and a storage bag.

FOUR Season
Four season sleeping bags are suitable for use during the coldest months of the year. Their premium materials will keep you comfortable in low temperatures and harsh conditions.
DOWN
Ounce for ounce, nothing insulates as effectively as down. Down-filled bags are very light, warm, and compressible. When cared for correctly, they will last for many years. The negative? Down is susceptible to moisture; when wet, its insulating capabilities will significantly drop. That is why some sleeping bags feature down with a hydrophobic treatment - it helps the down perform better and dry faster if it does get damp. Down is measured in fill power; it represents how much loft the down has. The higher the fill power, the better the warmth-to-weight ratio will be.
