Men’s Synthetic Insulated Jackets at Arc’teryx
Synthetic insulation earns its place on days when the weather will not behave: sweat from a climb, a damp ridge, a pack that gets stuffed and re-stuffed. Our men’s synthetic insulated jackets are built around Coreloft, which stays warm in light weather and suits high-output days.
How do the Atom SL, Atom and Atom SV differ in weight and warmth?
The Atom family of synthetic insulated jackets works as a ladder. The Atom SL Hoody puts stretch insulation in the body and none in the sleeves or hood, so it packs small for cold, wet efforts. The Atom Hoody is the all-rounder for chilly forest hikes, the crag and camp. The Atom SV Hoody is the warmest, with thermo-mapped insulation, a StormHood and full-length side panels placed for breathability on climbs. Add a hiking jacket over the top in rain.
Which synthetic insulated jacket suits alpine climbing, trail runs and skiing?
Beyond the Atom, Coreloft turns up in synthetic insulated jackets built for one job. The Nuclei SV Parka is a belay parka for severe alpine conditions with a helmet-compatible StormHood, the Norvan Insulated Hoody is the lightest, most packable synthetically insulated hoody for winter mountain runs, and the Allium is an insulated freeride softshell that works as a midlayer or standalone on the snow. Runners can pair the Norvan with trail running shoes.
How do I layer a men’s synthetic insulated jacket for wet weather?
A synthetic insulated jacket copes with light weather, but steady rain needs a waterproof outer layer. The Atom SV is designed to ride comfortably under one when the sky opens up, and a waterproof hiking jacket does the same job on trail days. When you want insulation and weather protection in one jacket, the Ralle and Beta Insulated pair Coreloft with GORE-TEX, and you can compare them in our waterproof insulated jackets.
Men’s Synthetic Insulated Jacket FAQs
What is Coreloft insulation?
Coreloft is the synthetic insulation used across the Atom, Proton, Beta and Norvan insulated jackets. It stays warm in light weather, and it comes in builds for different jobs: Coreloft Compact in the Proton Hoody for breathability, Coreloft Continuous in the Beta Insulated for cold mountain days, and a mapped build in the Norvan that focuses warmth through the core.
Does a men’s synthetic jacket stay warm when it gets wet?
Coreloft is made for it, which is why a synthetic insulated jacket suits damp days. The Atom Jacket’s insulation stays warm in wet weather, the Atom Vest performs even when wet, and the Atom Hoody keeps its warmth in light weather while still breathing on high-output days. For a long soak, add a layer on top and keep the synthetic jacket underneath.
Do I need a hood on a men’s synthetic jacket?
It depends on what goes over it. The Atom Jacket is the Atom Hoody without the hood, which suits wearing it under a hooded shell jacket. The Atom Hoody and Atom SV Hoody keep your head warm at camp and above the treeline, so they suit cold, exposed days where the insulation is the outer layer.
Should I buy a vest or a men’s synthetic jacket?
A vest keeps your core warm and your arms free, which suits long hikes and climbs where sleeves get hot. The Atom Vest has the warmth of an Atom Hoody with a wider range of motion and a smaller footprint. Wear it over a hiking fleece for cold starts, or choose a sleeved jacket if your arms feel the chill.
