Here's what others have to say...



  • Familiarity:I've put it through the wringer
  • Fit:True to size

I, like most everyone, love the Atom jacket. Within seconds of my mother seeing mine, she actually stole it and promptly went online and found that there was a vest as well and ordered that. Being more respectful of personal items I went out and bought my own vest - and have worn it nearly every day since (my husband has to pry it off me to get it into the wash).

It's a great weight and fits close to the body so you have warmth without the "puff factor" (It is Trim fit - so size appropriately!). The stretchy side panels create a nice athletic free moving fit which allows you to wear the vest for high intensity activities or layered over your favorite button down, merino top, etc. at the office.

Pockets are great on the vest but beware the zippers are very slim and not chunky.

Only complaint is that it isn't a little longer in the torso (I'm really long torso'ed so this isn't a fair complaint)
