Product Overview
Purpose
Many thermal garments are designed to keep you warm, but often at the expense of comfort and freedom of movement. Thick seams, unnecessary bulk, and restrictive construction can make them uncomfortable during long hours of wear.
ATOM™ was engineered to deliver dependable warmth while remaining exceptionally comfortable throughout the day. Its 270–290 GSM Performance Fabric, 4-Way Stretch Construction, and Brushed Inner & Outer Surface work together to provide efficient thermal performance without compromising flexibility or everyday comfort.
To further enhance the wearing experience, THM developed Trim-to-Fit Construction using anti-fraying fabric, allowing the neckline, sleeves, body length, and trouser length to be customised without compromising the garment's finish. Whether worn on its own during cool weather or as the foundation of a winter layering system, ATOM™ delivers lightweight warmth, unrestricted movement, and lasting everyday comfort.
