Light, versatile synthetically insulated hoody works as a midlayer and standalone. Atom Series: Synthetic insulated midlayers.




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.

Dope Dye


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



Versatile high performance designs for diverse activities and conditions.


Steeped in the alpine, this versatile hoody has warmed climbers, hikers, backcountry skiers and downtown commuters. Worn as a midlayer or standalone, it performs across a range of conditions and output levels. Coreloft™ Compact insulation retains warmth even if wet and has loft retention that withstands years of packing and unpacking. The water resistant Tyono™ 20 face fabric is soft, breathable and durable, stretch side panels improve ventilation and freedom, and the insulated StormHood™ adds warmth.

Size and Fit Tips: The Atoms offer more room in the body than their predecessors, the Atom LTs, for improved comfort, versatility, and freedom of movement.

Fitted Fit - This 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 our first layers. This model's fit has evolved. Before you check out, please make sure to reference our sizing chart to determine your correct size.

As an alternative to synthetic fill insulation, we also offer down fill products, such as the Cerium Hoody.
