Having a well-considered layering system is essential to a comfortable and safe experience when undertaking mountain activities in cold weather. Our range of men's base layers will help form that key next to skin layer as part of this.

Baselayers are just that, they're the base layer of your layering system and are designed to be worn close to the skin, trapping warm air against the body. Rab® base layers are typically constructed from merino wool and polyester fabric for optimal temperature regulation. Merino wool baselayers are highly breathable, insulating, lightweight, soft (when compared to other wools) and naturally antibacterial. With options for all environments and outdoor situations, the Rab® men's baselayer range features base layer shirts with long sleeve and short sleeve options in a variety of weights, as well as men's base layer pants.
