Designed to handle subtle climate shifts, the Atom SL is specifically created to hit the zone where insulation is required, but is also suited for milder conditions.
Balancing air permeability with wind resistance, the shell material allows airflow during active periods, but helps cut the chill during static moments. The Coreloft™ Compact insulation is highly compressible, insulates if wet, and delivers its superior performance for very little weight.
The trim fit minimizes bulk and layers easily, and the insulation is placed only where it’s most needed, in the core, to reduce weight and bulk without sacrificing appropriate thermal performance.
The Atom SL is an efficient mid-layer in cool conditions and a great standalone in milder conditions.
