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.

Ella ★★★★★ Oct 22, 2026

Finally a midlayer that keeps up with actual output without turning into a sauna the second you start moving uphill. The outer fabric sheds light rain like nothing, and the air permeability means I stopped having to yank my jacket off every five minutes on wet, mild days.

Hannah M. ★★★★★ Oct 21, 2026

I’ve been wearing this as my go-to layer for cold wet hikes, and the breathability is noticeable even when I’m working hard uphill. The slightly stiffer outer fabric handled a few branches without snagging, which surprised me. Perfect balance of warmth and air movement for damp 40-degree days.

Adam H. ★★★★★ Oct 20, 2026

The outer fabric shrugs off drizzle and brush without adding bulk, and the breathability keeps me from overheating on climbs where I'd normally strip layers. It's become my go-to for cool, wet hikes when I want protection without the clamminess.
