Atom SV Hoody Men's

$220.5 ~~$350~~ In stock

Category: Men's Synthetic Insulated Puffy Jackets & Pants

The best all around synthetic insulated hoody from Arc'teryx and the new replacement for the former popular Atom AR Hoody and Atom Heavyweight Hoody. A top pick for our Seattle Mountaineering Store for use in extreme wet weather when some customers will prefer a synthetic insulation layer. Synthetic Coreloft™ insulation still retains the majority of its insulation value when wet. This jacket is the warmest option in the Atom series from Ar'teryx, and can still be worn as either a midlayer underneath a rain shell or as your outermost layer like a lightweight belay parka.

Natalie ★★★★★ Oct 22, 2026

I’ve been wearing this for a couple weeks in damp 40-degree weather and the synthetic insulation keeps me warm even when it’s misty. The hood fits nicely under a helmet without feeling bulky, which is a huge plus for me.

Nicholas D. ★★★★★ Oct 21, 2026

I’m 5’10”, 170 lbs, got a medium, and the fit is dialed—snug enough to layer under a shell without feeling restricted. The hood’s trim and the insulated collar trap heat perfectly on windy November mornings, and it’s already my go-to for shoulder-season hikes.

Took this out in a heavy downpour and the outer fabric beaded water right off while the synthetic insulation kept me perfectly warm underneath. The stretchy side panels really help with mobility when I’m reaching for overhead holds on the trail.
