The Arcteryx Atom Hoody is a lightweight insulation piece for the active user providing insulation while ensuring mobility with a good level of breathability. Depending on the conditions, this versatile jacket can be used as either a super warm mid layer or an outer layer and for a range of activities.

The jacket uses Coreloft Compact 60 insulation, a lightweight synthetic insulation that is very compressible and light but expands very quickly when unpacked. Coreloft Compact 60 retains its ability to loft much better after repeated compression, extending the overall lifespan of the jacket. The outer is a lightweight and soft Tyono 20 fabric that has good air permeability and a DWR treatment on the face providing water repellency and wind resistance. The side panels in the body are Performance stretch fleece which provide this jacket with exceptional breathability and mobility, but if it gets really cold or you slow down it will be these areas where you will feel the cold first.
