Category: Men's Synthetic Insulated Puffy Jackets & Pants

Air permeable mid layer "active" insulation from Arc'teryx with abrasion and weather resistant outer fabric. A great choice for moderate temperatures when you are expecting a lot of wet weather on your outing. Synthetic Primaloft Gold Active Vent insulation still retains the majority of its insulation value when wet. This synthetic puffy jacket is warmer than the Atom and Atom LT Hoody, and lighter and more breathable than the Atom AR and Atom Heavyweight Hoody. This is the newest revised version of this jacket for Winter '24 with updated insulation and face fabric.

Samuel V. ★★★★★ Oct 21, 2026

Even on a damp, gusty trail run this jacket breathes well without letting the outer fabric wet out. The mid-layer weight is just right for hovering around freezing while moving.

Andrew ★★★★★ Oct 20, 2026

Been wearing this on cool, rainy morning runs and the air permeability is the standout—I stay warm without that clammy, sweaty feeling. The outer fabric shrugs off light drizzle and brush against branches without a scratch. Exactly the mid layer I was looking for.

Thomas ★★★★★ Oct 19, 2026

Took this out for a wet, drizzly hike and the outer fabric shrugged off the rain while the air-permeable insulation kept me from overheating on the climbs. The abrasion resistance is a real plus when brushing past branches. Solid pick for damp, moderate days.
