Nike

Shoulder straps are too narrow and dig in when the vest is heavy so you Can’t take too much out on a run. Anything over 2 hours and this is useless.

I love the vest! The ACG vest sizing was a challenge for me. The S/M sizes were way too small and the L size is too large. Still, the vest is great and perfect for summer. But, I would only pay full price if my body perfectly fit into one of these size ranges. The vest is awesome in design, colors, materials and functionality, for sure! Perfect for hot, humid steamy summer days in metro NYC ! Lots of pockets. The sizing of the vest is tricky. I am an "L" in the chest, but a "M" everywhere else - in this vest cut. I have never had this problem in any other Nike item. If you fit these Nike vest sizes available, then you will love this vest - the materials, design, functionality, colorway are so good! And a vest for running, activities and day-to-day usage is a necessity! Nike engineers are meticulous, and they will get the sizing matter right, I am certain of that! I would give it 5-star - if chest size fit more naturally (as in nearly every other Nike item for me).

As a lightweight running gilet this would be great apart from one major flaw that is the pouches for the hydration flasks. I use soft flasks and they are impossible to secure without them doubling up on themselves so it feels like you’re carrying a water balloon on each side. This is both annoying and very frustrating. Sorry Nike but this lets the product down immensely for me.
