Rated 5 out of 5 by from Great Piece Just got this mid layer and have worn it several times. Very warm, light, packable and nicely made. Seems to just hold heat when you want it. I like the full zipper for easy on and off. Looking forward to many years of service.

Rated 5 out of 5 by from Great ultralight fleece jacket I've been searching for an ultralight yet warm fleece layer for hiking and backpacking. The Rab's Alpha Flash fit me perfectly and performed great on the trail. I'm very happy with this purchase.

Rated 5 out of 5 by from Great alpha fleece, feature rich, great price too Great fleece for active hiking. I wear this with a Smartwool 150 weight base layer and a rab vapor rise on top down to the 20s(f). Very cold alone, I can feel the air move through the garment when I walk around in the house. The panels of elastane synthetic really round out the garnets fit because alpha fleece is very poor at stretching. These do not get in the way of arm pit ventilation. The pull strings are a rubber friction cuff that holds the pull string in place with no mechanism.

Rated 4 out of 5 by from Rab Mens Flash Jacket This is a great lightweight fleece that is perfect for any winter activities. Very breathable and comfortable but also very warm, works great so far

Rated 5 out of 5 by from Perfect mid layer Great mid layer , retains and or reclaims body heat when exercising and exposed to wind and cold temps . The garment keeps you from sweating out and is very comfortable
Date published: 2022-04-13
Rated 5 out of 5 by from Warmth to weight ratio is outstanding This is a superb midweight layer, very lightweight, and deceivingly warm. Meant to be worn under a shell or outer layer because there is no surface fabric on it, just the Polartec Alpha insulation. The plus side of that is, it is a stripped down very light, very breathable, packable midlayer. Just what I was missing for cold weather active outings

Rated 5 out of 5 by from You can never go wrong with Rab Honestly, I didn't know much about the properties of this jacket before purchasing it simply looked fabulous in the pictures. After it arrived I was very happy with comfort and fit. I didn't realize, but it's super light and super thin. It's very versatile and you can wear just alone or over a tee shirt and it's soft to the skin. It has very breathable so has no shell properties, however, used under any light shell it's perfect for a little added warmth. It really is a great extra layer with any jacket combination as it's light, fits well, and very comfortable.

Rated 5 out of 5 by from Toasty Rab Flash Jacket I usually wear women's size small, but since it wasn't available I decided to try men's small instead. Although the jacket has longer sleeves (love) it fits great, it's warm, and perfect for fall weather.

RAB FIT GUIDE
SLIM FIT: Rab Slim Fit garments are designed to be worn closer to the body or over layers such as base-layers and light mid-layers. Close fitting for maximum performance when moving dynamically.

REGULAR FIT: Designed to be versatile, Rab Regular Fit garments are not closely fitted for cross-seasonal use and multi-layering. Garments are contoured with room for movement.

EXPEDITION FIT: Expedition fit garments are designed to be worn in colder conditions and over more layers of clothing than our other fits and as such are oversized slightly to allow for this.
