I originally ordered these in a Large because like so many other brands of riding apparel, Sugoi tends to run small on me. They seemed to fit OK from the waist up , but they felt too loose from the waist down...and the leg grippers were extremely loose - they didn't even hug my legs! It appeared as if these bib shorts were actually going to run true to size...so I returned the large and got a small.
The small fits just about perfect from the waist down,save for the leg grippers - they are still a bit loose, just not to the point that they don't look like they grip my legs. Fortunately once I'm on the bike and the shorts hike up a bit, the leg grippers work like a charm. So only when I'm not on the bike are the leg grippers a bit loose, and even then it isn't to the point where its visible.
Unfortunately, now that the bottom half fits well, the upper half is quite tight. I wouldn't say that the shoulder straps are uncomfortable, but they are definitely noticeably tight. Fortunately they "disappear" after some time in the saddle. I'm hoping that if they're anything like my Giordana Fusion bib shorts (which fit quite tightly initially) they'll stretch out ever so slightly after a few uses, making them more comfortable.
The seam stitching is excellent because, despite the tightness of the upper half, the seams never dug into my shoulders or caused any skin irritation over yesterday's 96-mile ride. That said, a softer fabric would make the tightness of the upper half more bearable. The chamois is also superb. Advertised as Sugoi's top tier chamois, it certainly performed as such. My sit bones were comfortable for the entire 96-mile ride. My only complaint would be some numbness in the perineal region, perhaps maybe because there's too much padding down the center...but that's just a personal preference. Some folks are going to like the chamois more than me, and some will like it less than me, simply due to different body types/physiologies.
I gave this product 4 out of 5 stars for a few reasons:
1) The leg grippers don't fit as well as they could.
2) The fabric of the upper half could be softer to make up for the tightness.
3) The upper half doesn't seem to be proportional to the lower half (the upper half of the Large fit me while the lower half was way too loose, whereas the upper half of the Small is quite tight even though the lower half fits well), so I'm reluctant to assign a product fit to my review.
4) While the chamois give great support to my sit bones, it leaves something to be desired in the perineal region.
PS - two things the review doesn't ask for is my chest or waist size, which are 36" and 30" respectively.
