You can purchase Stickyseet breeches here. If you do buy a pair, I’d love to hear what you think!
Update Oct 2016: I have a new pair of burgundy ones (yay more colors!). It seems that the sticky nobs are even more pronounced and stickier now than on the black pair. So a bit of improvement on an already great product. I have had a bit of issues with the black ones starting to sag now, but that’s probably because I’ve been wearing the crap out of them and the fabric isn’t bouncing back as well anymore. I have also managed to almost rip one of the knee patches off (which I need to fix) from pulling my pants up when they start to ride down. These are still my favorite riding tight, even if their durability isn’t maybe as good as I hoped (the stitching)!
