My Showers Pass rain pants have a tendency to slip down as I ride. I read reviews saying that happened so I wasn't surprised when it did. Annoying to keep hiking them back up, so after that one ride I ordered these and all was resolved.
I have Showers Pass rain pants and was always pulling up the back for comfort coverage. Adding these suspenders made a good difference in my ride quality and enjoyment. Comfortable yet snug with the adjustable hardware. No binding into the shoulder, but tight enough to keep things in place. Fit as I expected.
These are nice suspenders, if you purchase the roadie pants from this same company they don't seem to stay up wo the suspenders and in fact should be sold with them. Your pants need suspender loops to work with these.
I have both the Shower's Pass Racer's Edge pants and the Commuter rain pants (convertible to rain knickers if what you want is wet socks & feet) Both pants don't ride in the crotch right for me unless they are up against my legs. Which figures, because if you have a lump of fabric down there you are sitting on that lump or it's binding as you try to pedal. The solution is suspenders, they hold your pants up, duh! The only issue is with the attachment point of the suspenders themselves is that they use this floppy D-ring and Velcro strap on the pants to hold them together. The D-ring wants to flip sideways creating this sort of knot of fabric that looks bad but actually everything still holds together.
So if you have any of the Showers Pass pants which take suspenders, and you have your pants in a knot, and pulling them up fixes it, get these suspenders.
