Factor 1 Plus Mens Short Sleeve Base Layer Top is engineered for performance, whether you're out on the hills, on active duty, or simply braving the British weather. Made in the UK using Sub Zero’s super soft hydrophilic polyamide yarns, it efficiently wicks away sweat, regulates body temperature, and resists odours — making it an essential addition to your kit bag.
This close-fitting, non-compressive base layer is lightweight, fast-drying, and kind to your skin, thanks to flat-lock seams and a soft inner face that prevents irritation. Wear it as your next-to-skin layer in warm or cool conditions — it won’t let you down.
