Thanks...I'll keep that in mind in case I order some! I have bike shorts from XS to M, so I am never quite sure which size to get. The mediums are Performance Ultras from a few years back, and I definitely could have gotten a small...the chamois is not too large, but I do have some puckering on the back seams. Still, they ran really small. The XS are PIs, and the Smalls are Terry. Sizing...what a pain!
