This vest is such a great item! I have worn it to work for some added warmth in my chilly office, but i have also used it to add warmth on a cold day out on the slopes or for showshoeing. It is fashionable yet functional. I usually wear a medium in Patagonia products and a medium fits perfectly with this item. It is slim fit, but that enables you to use it for layering. The vest fits well over a mid-weight base layer, with a jacket over top.
This vest is true to size, slimming, and super warm. The perfect layer for camping and living in! Highly recommend. I got the green/teal color which is better/brighter than I expected. Haha, I love this vest.
I might be completely biased because I'm obsessed with everything I've bought from Patagonia. I wear this vest at least three times a week from Fall to Spring. I love that it's lightweight but also keeps you warm. The fleece is super soft and durable. I'm a big fan of this vest. I'd wear it from hiking to going to a wedding just because it's that wonderful. I cannot recommend this vest highly enough.
