NOTHING CAN RUIN A FUN DAY ON THE TRAILS LIKE AN UNCOMFORTABLE CONNECTION TO YOUR SADDLE. We designed our new Mens Base Liner Bib Short to be lightweight and comfortable under your baggy shorts, with a chamois that allows you to get rowdy on the trails all day. They are constructed with lightweight, breathable materials and moisture-wicking side panel mesh, and they feature three Expandable Storage Pockets (ESP) so you can carry everything you need without a pack. And since you gotta go when you gotta go, the Mens Base Liner Bib Short features a fly opening.
