X - System Pro Series Fleece Apparel. "X" marks the spot for on - the - hunt comfort and scent control! X-System blocks your scent like nothing else! X-System"s scent-eliminating nanotechnology didn"t come easy... it"s the result of more than 10 years of university research. Nano-Silver fibers (which eliminate more that 250 types of microbes and the odors they cause) are integrated into each garment"s fabric. So X-System gear resists body odor throughout the life of the garment. It won"t wash out and it never has to be regenerated or reactivated like other scent-eliminating technologies. X-System clothing is also highly breathable and keeps your skin clean and healthy, because it actively inhibits bacteria growth. That"s why X-System is a favorite of men and women in the armed forces, who trust X-System gear in the field. Warm? Check. Scent elimination? Bingo. It"s a fact... no other fabric gives you a toasty core in cool weather like X-System! The moisture-wicking comfort of polyester fleece is soft against your skin, even after hours of tracking game. Best of all, the special Nano-Silver antimicrobial technology neutralizes AND prevents odors before they start, working to control scent-producing bacteria. Everything you want and nothing you don"t! A "scent"-illating value: 4-way stretch fabric means movement without restriction; No reactivation or regeneration required.; Machine wash, gentle cycle / tumble dry. Imported; State Size and Color.
