"Keeping warm, comfortable, and always perfect service."
"The Arc’teryx Cold WX wool base layer bottoms are amazingly warm. The comfort surpasses any base layer that I have used in the past. The elastic waistband is sturdy and holds the bottoms in place even during extreme activity. A must-have piece of kit when the temps drop."
"Thin enough to be comfortable under regular pants, but do an excellent job of keeping one warm."
"This is my second set. My first set lasted about 8 years. They would have lasted longer if I didn’t dry via a dryer. Very warm. Not the best to wear while very active (rucking) unless it’s really cold. But for semi active use it suits me very well here in the Minnesota woods."
"Amazing"
"Best base layer I’ve used"
"Great baselayer for managing body temperature and moisture! Good quality, durable, and great design and craftsmanship, Arc'teryx is top notch!"
