The Essential Vest

The men's Atom LT vest has become a seasonal layering essential. It provides the warmth needed for cool and dry commutes and layers effortlessly under a shell on wet alpine day-hikes. Arc'teryx built it with a durable and wind-resistant face fabric, which is coated with a DWR finish, yet still provides excellent air permeability. It's padded with 60g of Coreloft™ insulation, which is light, compressible, and makes this vest extremely warm for its weight. Polartec® Power Stretch® side panels with Hardface® Technology provide the stretchy strength and breathability needed for high-intensity activities.

  • Tyono™ 20 face fabric with DWR finish
  • Coreloft™ 60 insulation
  • Polartec® Power Stretch® stretch panels

Trim Fit | Wind Flap | Drawcord Hem

The men's Atom LT vest comes in a trim fit to a hip-length, for a shorter, slimming cut that's articulated for mobility and layering ease. The full front zipper closes the insulated collar, glides smoothly, and is backed by a breeze blocking wind flap. The lower hem is laminated and drawcord adjustable, helping prevent cold up-drafts. This vest can also be compressed into one of its pockets, making it perfect for air travel, backpack adventures, and daily commutes to the office.
