Rab Cirrus Flex Jacket
This lightweight synthetic duvet is a versatile insulating layer that's well suited to the UK's damp climate, says Charlie Low
Amongst the warmest full function belay jackets on earth the Citadel uses the finest synthetic insulation available, Primaloft One. Impervious to moisture it keeps going in the face of saturating semi-frozen icefalls and the differentiated fill ensures maximum warmth with mobility for seconding crux pitches. With 200g in the body and 170g in the arms and hood the Citadel is fully twice as warm as our legendary performer, the Fitzroy. Designed to throw over all your other layers it is sized large but the proven EXL elasticated lining eliminates cold spots and maximises thermal efficiency however minimal your clothing system.
Drilite Loft II is the perfect fabric for this application being super light and quick drying and yet having an impressive 1.5m hydrostatic head. Breathable enough for efficient drying of internal layers but weatherproof enough for the worst winter weather. Our legendary grown on helmet compatible hood provides a reassuring refuge from the horrors outside and a wired peak maintains vision of a battling leader in deteriorating conditions.
Chunky moulded zips are easy to operate even with large gloves on and four large pockets provide secure storage for topos, abseil cord and energy gels on the biggest lines. A large internal mesh pocket keeps vital fluids from freezing as well as warming dry gloves as the crux looms above.
Designed for hard, committing climbing in the toughest environments on earth this may just be the king of cold weather belay jackets. From four hour Scottish mixed pitches to one day sprints on the Moonflower Buttress the Citadel is refined equipment you can rely on.
