The ASSOS EQUIPE R Bib Shorts S9 is built for training, racing, and even just everyday rides where we need a bit more compression to help us through. Constructed Type. 443 fabric, these bibs are unbeatably breathable, super supportive, and even have a UPF 50 rating to keep our thighs protected from the sun's harmful rays. Plus, the Mono 9 chamois is thermoformed to reduce irritation and delivers just enough cushioning to keep us comfortable on race day.
