I figured I'd go ahead and compare the Atom SV with it's successor, the Atom AR.
Similarities:
– Coreloft
– Fleece lined pockets
– internal security zip pocket
– Gossamera face fabric
Differences:
– Atom SV uses 100g Coreloft all around
– Atom AR uses 120g Coreloft in the body, 60g in the sleeves, 80g in the hood
– Atom AR has an adjustable "halo" hood toggle that works like the the Cerium Lt and Patagonia puffies, offering better coverage
– Atom SV uses two toggles in the front for hood closure, and one in the back for adjusting 'vertical' tension, pulling the brim up
– Atom SV has fleece fabric in the face area, Atom AR uses a zipper garage but no fleece
I still think the Atom AR is one of the best on the market, but there are a lot of great synthetics out there that compete- although none offer the combination of fit, fabrics and features- IMO.
