What is the Atom SL Vest?The Atom SL is the lightest weight synthetically insulated gilet from Arcteryx. It's perfectly suited to cold, fast-paced mountain adventures like running and biking but also works well as an extra light layer on chillier summer evenings.
What is it made of?Insulation: The Atom SL Hoody has 40g/m² of Coreloft Compact in the body to maintain core temperature during mid to high output activities. Coreloft is a synthetic insulation that is similar to Primaloft, however, it has been developed by Arc'teryx to be more durable. Not only is it more durable, but the synthetic fibres have also been siliconised to further increase breathability by reducing their ability to hold onto moisture.
Outer Fabric: The outer is a combination of a tough Tyono 20 denier 100% nylon fabric and an air-permeable fabric in the side panels. The main fabric is surprisingly tough despite its low weight, water-resistant, wind-resistant and incredibly packable. The side panels are made from a Bluesign-approved polyester fleece fabric that has an antimicrobial Polygiene treatment to avoid the build-up of nasty smells. These side panels allow warm air to escape, keeping you at a comfortable consistent temperature, they provide stretch for high-aerobic activities and improve the overall fit of the vest.
What are its features?The Atom SL Vest features two zipped hand pockets for essentials, an adjustable hem to seal in warmth and a No Slip Zip which has little speedbumps to prevent it opening during use.
How does it fit?The Atom SL fits into Arc'teryx's 'trim' fit block, meaning it sits more snugly than their 'regular' fit for improved performance. The centre back length measures 72cm in a size medium.
Where does it fit in the layering system?The Atom SL Vest works perfectly as either a warm midlayer or a lightweight outer layer in milder conditions.
