Innovation and durability are what Arc'teryx lives by. Every product is made to be resistant and versatile.

Versatile hoody

Atom LT Hoody Features

The Atom LT Hoody is an essential colder weather piece for the active man. The light yet wind resistant taffeta fabric is treated with a DWR finish (durable water repellant) to help repel water from its surface. In addition to providing breathability and warmth thanks to the Coreloft™ insulation, the side panels are made of Polartec® Power Stretch® with Hardface™ technology, regulating the body's temperature during activities. Highly compressible and lightweight, this mid layer can be stored in its own pocket or tucked inside the hood. It takes almost no space and a quick shake is all you need to restore its original loft, every time.

  • Breathable, stretch side panels for enhanced comfort and mobility
  • Full front zip with wind flap
  • Soft brushed-lined collar
  • Stretch-knit cuffs
  • Drop back laminated hem
  • Adjustable hem drawcord
