How does the Atom SV differ from the Atom LT and Atom AR?

The SV is the warmest of the three, with more insulation for frigid, exposed conditions. The LT is a lighter, more breathable midlayer, and the AR sits between them. Choose the SV when warmth matters more than packability.

Is the Atom SV warm enough on its own in winter?

It is built for frigid hikes and above-treeline cold, and Arc'teryx positions it as hefty protection on its own. In wet or windy storms it is meant to go under a hardshell.

Does the synthetic insulation still work when wet?

Yes. Coreloft synthetic insulation keeps you warm even when it gets damp, which is the main advantage over down in wet cold.

Can I wear it under a hardshell?

Yes. The updated streamlined fit is designed to ride comfortably under a shell when the weather turns.

No. The Tyono 30 face fabric is wind-resistant and has a PFAS-free DWR finish that sheds light moisture, but it is not a waterproof shell.

What is the StormHood?

It is Arc'teryx's insulated hood, designed to seal in heat and stay put in wind. It adds head warmth without a separate hat.
