Very positive. Fit snuggly, good elastic so far.
As someone who works for a running apparel company made in the USA, I try and support other made in America companies. I'm happy I chose OrNot for my jersey, bib, and sock purchase. Stoked to have my first high end kit. As your typical string bean athlete, 5'11 & 140, the sizing is true to fit. The Mt. Tam Sock 15' is a great ultralight sock with lots of breathability. Also a plus is that they are bright enough to add that extra pop to force the cars to see that you're on the road.
