The Microlight Alpine Jacket is a lightweight, narrow baffled down jacket with a weather resistant Pertex outer fabric. 

Rab says:

The Microlight Alpine Jacket is the lightweight down jacket you can take anywhere, designed for use in situations where warmth, weight and packability are prime concerns.

Constructed with Pertex® Quantum outer fabric, the Microlight Alpine is windproof and breathable, using 750 fill power ethically-sourced hydrophobic down to provide exceptional warmth without compromising on weight. Features include an adjustable hood with laminated brim and flexible polymer peak, diverted hood baffle lines for an anatomical fit, and clean finish elasticated cuff construction. Two harness-compatible hand pockets and a chest pocket provide easy access to storage. Highly compressible, the Microlight Alpine Jacket comes with a stuff sack which can be clipped to a harness or backpack.

Inspired by decades of experience in the mountains, the Microlight Alpine is refined, resilient, and iconic: perfect for any adventure.

Rab's Microlight Alpine jacket is one of our best selling down jackets and is now a refined garment with 10 years experience behind it. A mini stitch-through baffle construction and a minimal, uncluttered design make the Microlight Alpine Jacket a perfect layering piece for alpine climbers, or an adaptable stand-alone jacket for day to day use.

The latest incarnation of the Rab Microlight Jacket has some slight tweaks with an improved fit, the pocket openings being placed at a more comfortable angle, improved cuffs and a hood which has a lower profile on the jacket when not in use.
