Streamlined and breathable, this wind-resistant core layer disappears when you dont need it and adds a layer of protection when you do.Rab says:Our bestselling multi-activity softshell vest is back, now built with a recycled fabric and offering unbeatable breathability and wind resistance without the bulk of sleeves. The stretchyMatrixfabric allows freedom of movement for tackling tough ascents, while drying quickly and moving moisture from the inside out when youre working up a sweat. Lightweight, packable, and incredibly versatile, this all-mountain vest is at home whether you’re running a windy ridgeline, ski touring, or scaling a rockface.Our VerdictThe Rab Borealis Vest weighs 168g in Medium and uses Rabs Matrix fabric, offering enough wind protection without sacrificing airflow. Its ideal for fast-paced walking, cool starts or breezy summits where a full jacket would be too much. The stretch is excellent, and the slim fit stays put without riding up or feeling restrictive under a pack.Two chest pockets are mesh-lined and sit high enough to stay usable with a hipbelt. The elasticated armholes and hem are low-profile but effective at sealing out gusts. The fabric dries quickly and doesnt feel clammy, even when working hard. Ive appreciated how quiet and supple it is compared to a standard wind jacket. – Reviewed by Ultralight Outdoor GearFeaturesYKK zipped, mesh-lined chest pocketsElasticated armholes for stretch and comfortDual Sided rear hem adjustment with single-handed adjustmentSpecificationsSmall weighs: 161gMedium weighs: 168gLarge weighs: 177gXLarge weighs: 196gFit: SlimCentre back length: (Size M): 71.5cm/28.1inchMaterial & ConstructionMatrix single weave stretch nylon (130gsm) with fluorocarbon-free DWRMain Body: 88% Polyamide (Recycled), 12% Elastane, Pocket Bag: 100% Polyester (Recycled)Help & advice:About RabChoosing a Softshell Jacket
