Despite its cool and uncomplicated, almost street looks, Arcteryx's Arenite is effectively a technical fleece designed as a cold weather midlayer.
Arcteryx calls this fleece Cobblecomb, which is lofty and soft to the touch, successfully trapping warm air near your skin, while effectively wicking away moisture so that you don't get sweaty on the inside when the intensity increases.
The outside of the material has a more durable and friction-reducing twill face that is designed to more freely, without binding, underneath your outer shell jacket.
This works well, helped no doubt by the fitted cut and narrow arms of the Arenite, which holds your form supportively thanks to its elastane stretchiness.
Features are minimal and subtle, with a tall collar, a full-length front zipper, and two hand pockets on the front. Gusseting under the arms also helps with articulation.
The versatility of the Arenite is that although designed for ultimate warmth under a shell and over base layers, it's easily warm and stylish enough for a top layer on cool summer nights.
