Good fit & ventilation - what's RECCO?
I read the sizing chart and happy I did, I'm 5'10" and the size small fits me perfectly. I typically wear a medium in most brands, but follow the sizing chart that Rocky has online.
What's RECCO? There is a patch on the right sleeve with "Recco" printed on it, I had to look it up - Rocky implants a passive tracker on the arm for the worst case scenario that you can't be found. Apparently, it's trickle down tech from skiing etc., but it's a nice touch, hopefully having it means that I will never need it!
