Category: Men's Synthetic Insulated Puffy Jackets & Pants

The new version of the popular all around synthetic insulated vest from Arc'teryx. Made with new synthetic Coreloft™ stretch insulation that still retains the majority of its insulation value when wet. This low-profile vest is very lightweight and is a great layering piece that adds extra core warmth to your clothing systems without impeding the ventilation through your arms. Stretch fleece side panels further breathability and provide a more low-profile fit when worn as a mid-layer underneath your outer storm shell or ski/snowboard shell.

Jacob K. ★★★★★ Oct 21, 2026

Finally a synthetic vest that moves with me instead of riding up when I reach overhead. The Coreloft stretch insulation is noticeably more flexible than my old static puffy, yet it still feels warm even after getting caught in a light drizzle.

Emma ★★★★★ Oct 20, 2026

Swapped out my old fleece for this vest on damp autumn hikes, and the way the Coreloft stretch insulation kept me warm even after a light drizzle was genuinely impressive. It's lighter than I expected but packs a surprising amount of warmth for its weight.

I mostly wear it for chilly morning runs, and the stretch insulation moves with me without any restriction. It packs down small enough to stuff in my bag when the sun comes out.
