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 are a key component in achieving 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 a blend of merino wool or polyester fabric for optimal temperature regulation. Merino wool base layers 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 base layer range features base layer tops with long sleeve and short sleeve options in a variety of weights, as well as base layer leggings.
