Love this vest!

  • Gender: Male
  • Familiarity: I've used it several times

This is a perfect vest, sized just right for either midlayering or over a shirt. Note that the size runs on the snug side. I have a 43" chest, and got the large. I would call the fit "snug", but would probably be "compression" if it was an inch smaller. Love the athletic cut and the reflective stripes on the front.

Great layering piece

  • Gender: Male
  • Familiarity: I've used it several times

The vest is one my "goto's" from now on. It layers very well, not bulky, and also does well as a stand alone when it warms up. I purchased an XL 6'1" ~ 205 - fits great.
