Excellent product overall: fit and design are on point. They provide support where you need it and they’re just so comfortable.

Not perfect, but pretty close

I've been on a quest for a few months to identify the boxer briefs that will refresh my entire drawer. But before ordering a doz+ pairs form anyone I've been ordering one at a time trying them. For me, thus far, these are the winners. The fit is great. Very comfortable. The fabric is not too heavy or warm. The "pouch" works and you really don't have to put the boys in, they just sorta end up in the pouch. That said this pouch is not as supportive as say the pouch by "All Citizens". But you have to 'put' you boys in that one.

The parts that are not 100% perfect -
- Pouch could be a little more supportive (like All Citizens... but not all Citizens, thats too much)
- Legs could stay in place better... not sure how to do this and maintain the current comfort level but thats my pipe dream.
- Waist bad folds... granted if I was not such a fat fux I'm sure it would not be a problem... I guess I cold just loose 20lbs.

Best I've found thus far... I like more than All Citizens, Mack Weldon, Nike, Adidas...

Partner likes them

His cotton pants deteriorate so quickly. Synthetic Rapha pants have kept their shape, colour and integrity - no longer sold. (He'd also said synthetics were more comfortable to cycle in). He said Crossfly were, "Very good." Like other reviewers here I will buy more in the future. He has a 37" waist and liked the medium. I bought one large - just in case - he "didn't pay too much attention to it" so they were tolerable, no need to return. He wears them under cycling tights, commutes 8-9 miles each way, continuing to wear them under work trousers all day, under loose trackies at home.
