The XKG Merino Bottom is the perfect next to skin base layer bottom for when temperatures begin to drop. 19.5 Microns and 260 Gram knit makes these bottoms lightweight, but the small, tightly sewn fibers of merino wool keep you warm in colder conditions. With a high heat to weight ratio, you can rely on comfortably hiking without the fear of over-sweating. We added a full-length zipper on each leg for easy removal when out in the field. Each leg is only three quarter length to stop just short at the top of your boot for easier removal. Never take your boots off again when the temps begin to rise. Simply pull down your outer layer, zip off merinos, pull pants back up, and keep hunting.
