Technologies:

Omni-TECH™: Columbia's multi-layer waterproof and breathable technology. A thin membrane is bonded to the inner face of the fabric: it blocks liquid water and wind while allowing moisture vapor produced by exertion to escape. The result: you stay dry from the outside without overheating.

Omni-HEAT™ Infinity: a grid of thermal reflective dots covering a large area of the lining to maximize retained warmth. The airy structure between the dots facilitates moisture evacuation: warm without overheating.

HeatSeal™: a construction process that bonds the insulation baffles to the fabric rather than sewing them. It helps reduce cold spots with a system of airtight baffles.
