Jon wrote a review of Nike Snowboarding 550 Fill Vest - Men's on January 21, 2013
Familiarity: I've used it several times
After searching through the normal Patagonia/Marmot/TNF/etc gang for a decent casual vest, I ended up deciding on this Nike vest among all things.
Sizing: Way Big! I'm 6'3" and 185 and thought the Large would work...WRONG, absolutely HUGE on me. Bought the Medium and it's almost a perfect fit. One of the few vests that actually has some length to it, in fact it would probably fit someone that was 6'5" or so - again, plenty of length.
Dislike: No side pockets. Yes, there are front pockets, but nothing for your hands. Side pockets would have made this good vest absolutely great.
Good Things: Hem drawstring to hold in the heat. Like the two front pockets in addition to a velcro interior pocket. 550 fill down is actually extremely warm, probably because there's a decent amount of fill. On par with my 800-fill down Patagonia Sweater Vest. Collar is not ridiculous looks normal, unlike some vests I've tried on. Finally styling - like it a lot. Looks very similar to the Patagonia Slingshot vest, but since Patagonia had crazy sizing on that line of vests, none of them fit me.
Again, love this vest, just really wished it had hand pockets.
