Past season

The Atom LT is the perfect mid layer for cold days. Made for active women, it offers excellent insulation and breathability, while also being windproof and beading water from its surface. On warmer days, it can be worn by itself.

At Arc'teryx, to challenge what exists and manufacture new ideas is the culture. Passion and curiosity fuel a continual drive to explore, to push the boundaries of what is known, regardless of assumptions.

Mid layer for added warmth

For maximal warmth, the arms and torso are fortified with Coreloft™ insulation, while the side panels and underarms incorporate Polartec® Power Stretch® with Hardface® Technology to increase mobility and breathability.

Atom LT Jacket Features

The Atom LT has a water-resistant and windproof surface that stays breathable. It's insulated, but still lightweight, compressible and compact. The elbows are articulated for a better liberty of movement and the zipper has a wind flap that adds protection against the wind.
