Rab Women's Microlight Alpine Jacket - Black - UK 12 (M)

For alpine climbers and mountaineers facing cold, changeable conditions, the Rab Women's Microlight Alpine Jacket delivers reliable warmth without excess weight. The black UK 12 (M) jacket uses 700 fill power recycled hydrophobic down, treated with a Nikwax fluorocarbon-free finish, to maintain loft and insulation even in damp environments. The outer is 30D Pertex Quantum ripstop nylon with a DWR coating, while the inner is 20D recycled nylon for next-to-skin comfort. Zoned lightweight micro and nano baffle stitch-through construction optimizes warmth distribution and reduces bulk, making it an ideal midlayer or standalone piece for alpine climbing, mountaineering, hiking, and general outdoor use.
