A super-warm, very comfortable, high performance down-filled sleeping bag.Rab’s Ascent range of sleeping bags are duck down filled performance sleeping bags designed for regular use – the Ascent 900 is the warmest, built for use in colder climates.Made using durable and lightweight Pertex Microlight fabrics, they give you durable build and construction, with very effective warmth for bags of such low weight.The Ascent 900′s roomy semi-rectangular foot area gives you space to move without losing insulation, which is great for those who don’t like the restriction of a mummy shaped bag.The Pertex Microlight* outer shell and inner lining is ultra-light and very densely woven, holding the duck down fill in place without obstructing the bag’s breathability.It comes with two storage sacks – a large storage/carry sack, and a compression stuff sack – giving you the option of compacting the bag down to conserve space in your kit, or keeping it uncompressed for long term storage, to preserve the down.Rab® fluorocarbon free Hydrophobic Down developed in conjunction with Nikwax®Pertex® Microlight inner and outer fabric650FP European Duck DownWide mummy shapeProportionally assigned differential cutInternal YKK 3 coil zipped stash pocketWide foot area for extended comfort3⁄4 length YKK 5 coil main zipLeft and right hand zipped bags will zip togetherAnti snag zipper webbing tapeInternal collar and hood drawcordTrapezoidal baffle chamber designAngled foot boxCompression stuff sack, cotton storage sackWeight: 1530g/54oz (+170g/6oz stuffsack) Hand filled in Derbyshire
