Product details

Summer weather is warm, until it isn’t. So compact and light, there is no reason to leave it behind, our lightest Atom is there for you when the temperature drops. Strategically placed at the chest and back, the Coreloft™ insulation is efficient, light, and compressible. The Tyono™ 20 outer balances airflow with wind resistance and has a DWR finish to repel moisture. Stretch fleece side panels ventilate and an uninsulated hood adds coverage and buttons out of the way when not in use.



Our trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over first layers or under outer layers.


Atom: Versatile synthetic insulated mid layers with a high degree of weather resistance.

Synthetic Insulation: Man-made insulation with quick dry times, durability and retains warmth when damp.

Multi Use: Versatile high performance designs for diverse activities and conditions.

Dope Dye: Adding pigment at the polymer level which saves water, reduces C02 emissions and increases fabric colourfastness.
