I got the 34" belt. I wear a 31 waist in the 501s and 511s, and the belt fits perfect on the middle notch. When riding my bike I loosen the belt a notch and can fit my U-lock under it in a similar style to the 511 Commuters. The belt doesn't have a logo or any brand marking that shows while wearing it.

Have had the belt for a week, and while the overall construction seems ok, there is this unbearably strong smell of cheap leather that permeates everything around it. It’s actually not the smell of leather itself per se but rather the chemicals they may have treated it with. It made me nauseous after wearing it for 1 day breathing it all day at my desk (yes its that strong!). The smell also carried over onto the jeans; the odor now has taken over the entire walk in bedroom closet.
