I didn’t know I was a vest guy

I didn’t know I was a vest guy until I got this vest. I figured if it was cold enough for a jacket I need my arms covered but learned this one lets me vent some of the heat out when I get hot running. I’m warm but not too hot and it has all the storage you’ve come to expect from FlipBelt
