The Arc'teryx Atom Hoody delivers lightweight, breathable warmth for changing mountain conditions. Built for hiking, climbing, skiing, and everyday cold weather use, it works as a midlayer or standalone piece when temperatures drop and output stays high.

Coreloft™ synthetic insulation traps heat while staying efficient in damp conditions. The outer shell adds wind resistance and light weather protection, keeping comfort consistent during stop-and-go activity in alpine or urban environments.

Stretch fleece side panels improve breathability and mobility during high output movement. The updated fit supports layering without restriction, making it a reliable system piece for year round use.

The StormHood™ design adds insulated coverage with an adjustable structure that maintains visibility and warmth. Multiple zippered pockets secure small essentials during travel or outdoor sessions.

Features

  • Lightweight synthetic insulated hoody for active use
  • Coreloft™ insulation retains warmth in wet conditions
  • Wind resistant outer fabric for added protection
  • Stretch fleece side panels for mobility and breathability
  • Adjustable StormHood™ for coverage and insulation
  • Zippered hand pockets for secure storage

Why it works

The Atom Hoody balances warmth, breathability, and mobility in a single layer. It performs across mixed conditions where insulation alone is not enough and full shells feel excessive.
