The Rab Microlight Alpine is a slim fitting incredibly light and protective down jacket, making it the perfect mid or outer layer for those demanding exceptional levels of warmth, but who also want to carry a jacket with little weight and is small to pack. This is a great piece of kit for the Adventure racer, mountain walker or the lightweight alpinist.
The outer is made of Pertex Microlight fabric which is a very lightweight fabric that is highly breathable and windproof. This combination enables the Microlight Alpine Jacket to be used as either a midlayer or an outer layer depending on the conditions. The 750 Fill Power (US) European goose down is held closely in place by stitched through narrow baffles, ensuring enduring warmth for the wearer.
The shape of the jacket is designed to allow unrestricted movement. The down filled hood will keep your head warm and has a wired peak whilst the elasticated cuffs and hem drawcord keep spindrift out. Please remember that this is a lightweight down jacket for active use, if you require greater insulation then consider a heavier jacket.
Hydrophobic down is used to provide better performance in damp conditions. This is achieved by washing in a Nikwax coating in the early stages of production. This down is NOT waterproof, but will retain its loft for longer if it gets damp, and will dry faster.

This lightweight down jacket from Rab has been in my bag all winter and has been part of my system of keeping comfortable in cold and semi-cold conditions.
I would normally change between carrying a full on down jacket for ice climbing or when temperatures are really low, then switch to something lighter later in the winter or on mild days. With the Microlight Alpine jacket I have not needed to do this as it is small and packs into the chest pocket to stow in the bag at all times, and for the remarkable weight and packability it delivers a lot of warmth. I use one size up so that it can be pulled over the top of my mid layers and shell jacket, but I have found it is also comfortable under the shell. Beware sharp objects though - as lightweight means that if it even glimpses a sharp ice axe there will be feathers all over the mountain!
