Customers praised the vest's warmth, slimming fit, and quality construction with "silent warmth" and functional pockets. However, sizing runs significantly small—many shoppers recommend sizing up as even XL customers struggled to zip it. Those who ordered their correct size found it "fitted" and restrictive for layering.
Very nice vest. It is fitted so if you want something roomy size up.

Love it!!!
Looks and feels amazing in person!! Love the pockets and how slimming it is while holding warmth at the same time. I’m usually an XS in women’s tops and I like how XS feels for a snug fit so I can still run without it moving all over the place!

Silent Warmth
Love it! Fits perfectly. You don’t even realize you have it on. By that I mean it doesn’t get in the way. I’ve already worn it for three 5K races.

Too small
I ordered and returned this immediately. It looks well made and high quality but way too small. I ordered a medium. I usually wear a medium or a small. I was able to zip it up but could barely move. And could not fit anything under it. I was afraid to try a large, I wasn't sure even that would fit.

Runs SMALL!
Got this today and holding it in my hands it looks/feels great. Love all the pockets, and the thicker vs thinner areas to try and prevent overheating. But I put it on and it's so small I can't even zip it up! I'm an XL in women's tops in most brands, so I ordered an XL vest, but this does not fit like other XL things. It might possibly have zipped if I stretched it to the max, but I don't fancy feeling like a sausage casing about to burst when I go for a run so it's getting sent back.
