The Essential Hoody

The men's Atom LT Hoody is an Arc'teryx essential for a reason. It has the thermal capacity for mid layering on wet seasonal hikes around Banff and the standalone warmth for year-round cycling commutes in Vancouver. It's padded with light and compressible Coreloft™ 60 insulation, which provides substantial warmth for its weight. Polartec® Power Stretch® side panels with Hardface® Technology give it the flexible strength and breathability needed for outdoor activities. It's then furnished with a wind-resistant Tyono™ 20 face fabric, which is coated with a water-repellent finish, while still having excellent air permeability.

  • Coreloft™ 60 insulation
  • Polartec® Power Stretch® stretch panels
  • Tyono™ 20 face fabric has DWR finish
  • Trim fit, hip-length
  • Articulated elbows, gusseted underarms

StormHood™ | Wind Flap | Hem

This Atom LT comes with an insulated and rear-drawcord adjustable StormHood™, which has a low profile, is designed to move with your head, and fits over a bike or ski helmet. The full front zipper closes around the chin, has No Slip Zip™ to prevent self-opening, and is backed by a breeze blocking wind flap. The lower laminated hem is drawcord adjustable, helping prevent cold up-drafts. This hoody is also compressible enough to pack into one of its zippered pockets, making it perfect for travelling or outdoor adventures where space is tight.
