Ultralight Merino-blend base layer for high-output activities and warmer days. Made for higher output and warmer days, our lightest base layer bottom is the year-round solution. Made from an ultralight 150gsm fabric, it combines Merino wool – known for temperature regulation and odour control – with super-soft TENCEL fibres and nylon for durability. Betaspun technology combines the fibres into a single ultralight yarn that feels comfortable on your skin, withstands abrasion, and resists pilling.
