Fiber vest of the brand Arc'teryx designed to protect us in cold weather conditions.
The Atom LT vest is light, warm, breathable and with a perfect pattern to allow mobility in any mountain sport, being highly recommended for activities that involve a lot of arm movement such as climbing, climbing on ice, snowshoeing and ski touring or in other mainly aerobic situations. Can be used as a mid layer in severe cold conditions. Comparatively, its insulation is comparable to that of a medium thickness fleece vest but with a significantly lower weight and a much higher compactness.
Perfect for use as an insulating layer since its Coreloft™ Compact 60 provides adequate warmth and necessary breathability. Coreloft™ it is a uniform material (it is not woven by warp and weft threads) formed by a mixture of multidenier silicone polyester fibers of various sizes, both in length and thickness; the shortest fibers are those that allow excellent thermal comfort by allowing air to be trapped in them and the continuous fibers give consistency to the whole and allow a good recovery of the garment after being subjected to compression. In fact, the Coreloft™ it has been subjected to a process to compact it by 50% without reducing its thermal capacities in the same proportion; in the case of the Atom LT vest, the amount of padding is 60 grams per square meter of fiber. Being a hydrophobic material, it continues to keep you warm even when wet, making it an excellent material to use in humid conditions such as fog, storms or in case of excessive sweating if we have to increase our pace at a certain moment.
The outer fabric Tyono™ 20 consists of a material made up of 100% elastic Ripstop Nylon of only 20 deniers, so we find ourselves before a fabric that is as resistant and durable as it is light. It has been given a finish with DWR (Durable Water Repellent) treatment that provides water repellency. In addition, it incorporates side panels made of elastic fleece fabric, a material composed mainly of polyester (94%) but with a good proportion of elastane (6%) to increase mobility and breathability. The result is a highly adaptable fabric that breathes and disperses moisture with a very pleasant touch.
Adjustable and technical cut of the garment to adhere well to the movement of the body during the activity and to be able to use it without discomfort with other elements such as a third layer jacket, backpack or harness without forming uncomfortable wrinkles. The bottoms of the vest are laminated and are adjustable with two elastic straps and the back hem is slightly longer to allow the body to flex without exposing the lower back.
Mid-rise collar features fleece insulation and lining. It combines well with other clothes.
Light vest with great compression capacity, the result is a warm garment weighing only 240 grams and compactable in a very small size.
Full front zipper No Slip Zip™ with custom TPU straps and chin guard. Two outside pockets with hidden zipper and one inside pocket with zipper.
Soluble dyed lining. Materials compatible with the Bluesign® criteria.
