The Rab Mens Microlight Alpine Down Jacket is made for days when down warmth matters but pack space still counts. Its recycled 700FP down has a Nikwax hydrophobic finish to support performance in damp conditions, while the Pertex Quantum outer helps block wind without turning the jacket into a bulky outer layer.

Rab zones the baffles rather than using the same construction everywhere. Micro baffles through the body and shoulders keep insulation around the core, while smaller nano baffles under the arms help manage heat when you are moving uphill or wearing the jacket under a shell. The down-filled hood adds coverage when temperatures drop, and internally elasticated cuffs plus the drawcord hem help keep warmth in.

At 466.5g (16.5oz), it stays light enough to pack for changeable mountain weather, with three zipped pockets for small essentials. It is the kind of layer that earns regular use when the forecast shifts and you still want down warmth without unnecessary bulk.
