Kirk W wrote a review of ExOfficio Give-N-Go Brief - Men's on June 2, 2014
Familiarity: I've used it several times
Fit: True to size
I own two pairs of these and they are as advertised. They're underwear and they work - what else can you say?
The fabric is kind of mesh-like, resulting in chafing a few times on long, hot days. The heather color material in particular seems to be a little more coarse. I personally prefer the Capilene fabric in Patagonia's briefs as Capilene is a bit softer, but the Ex Officio product does work as advertised! They dry very quickly and tend not to retain stink. I've worn them for 3-4 days straight with good results.
