Warmth and weather resistance in a slim, lightweight and very comfortable package - now available in web exclusive colours.

The Rab Microlight Alpine Jacket couples effective down insulation inside with weather-resistant Pertex Microlight outer fabric in a streamlined package that gives you the maximum warmth with minimal weight.

Roomy, zipped pockets give you ample room for essentials, and the whole jacket can be packed away into the supplied stuff sack (in some older versions it stuffs into its own pocket) for easy storage or to make a usable pillow.

Rab's fluorocarbon free Hydrophobic Down  is their usual high quality European down, but treated with a water-repelling coating so it's more water resistant and will maintain its loft. It performs more effectively in damp conditions than untreated down - it absorbs less water, dries faster, retains loft and is fluorocarbon free. Stitch-through baffle construction helps to keep the down in place, preventing cold spots from developing.

Its narrow-baffled construction prevents the down fill from spreading or bunching and gives maximum loft, and the fixed insulated hood (with positionable peak) gives you supreme protection from winter weather.

Clean lines and a slim silhouette mean that the Microlight Alpine works very well as a layering piece under a waterproof shell, for climbing or other alpine pursuits - but it's equally at home if you're lightweight backpacking, or just wearing it day-to-day in cold conditions.

Rab Microlight Alpine Jacket, 22 April 2017
By Nigel (Co Antrim)
As soon as I seen and tried on this coat I wanted it. Very light, warm, comfortable and fits perfectly to the body. It's true what they say in life you get what you pay for. Very impressive.

Rab Microlight Jacket, 17 April 2017
By Flynny (Preston, Lancashire)
I bought this Jacket online after trying one on for size at a local outdoor store. I love it! the jacket is an XL as i am 6'4" with long arms and it fits perfect. I haven't worn it out on a walk nor in the rain but as my go to jacket for wearing with jeans etc. I will use this in a layering system when I do go walking as it fits nicely alongside my other RAB clothing. I would definitely recommend buying

Great Piece, 28 February 2017
By Mike (Plymouth)
Had a few issues with down escaping from my first jacket but was timely replaced by go outdoors even though it was an online order collection. Second jacket seems to be much better, few feathers here and then but you can easily wiggle them back in by pinching either side and moving your fingers.

Warmth to weight ratio, I don't think you can get a better jacket. Pertex microlight lacks a bit of durability but this piece would usually be worn underneath another layer anyway.

Relatively good breathability for a down jacket and relatively good water resistance too. All those moaning that it isn't waterproof, it was never advertised as waterproof.

Gutted that these jackets are now becoming a fashion statement with the youth of today. Rab will soon become the new North Face.

Fantastic coat & fantastic bargain., 02 February 2017
By Clive (Keswick,Cumbria)
I wanted a lightweight, warm jacket for walking and this jacket is perfect. Stylish, comfortable, light and really warm. I decided on the red and am so pleased with it. I'm warm with just a base layer tee shirt on. As our local stockist had no stock I found it on the Go Outdoors site and cheaper. Fantastic coat & fantastic bargain.
