Soft, warm and ready for outdoor action, this 1/2-Zip Sweater boasts the power of Agion Active™, a silver-ion antimicrobial treatment. This technology provides industrial-strength odor elimination and reduces odors both on and around the fabric. Agion Active performs for the life of the garment, regenerating with each wash. The 5.5-oz. fabric, crafted of 50/50 merino wool/polyester, offers the perfect blend of softness and warmth. For superior temperature control, the side vents and the front 1/2-zipper allow excess heat to escape. When you feel cold, pull the zipper up and the 10" front mock neck and the rib-knit cuffs seal in the heat. Moisture-wicking, quick-drying fabric maintains a comfortable dryness. UPF rating of 40. Machine washable. Imported. Center back length: 28". Sizes: M-2XL. Colors: Black, Woodchip.
