“These bibs run quite tight, so I would not trust the sizing calculator recommendation. For me at 169 cm, 61 kg with a lean athletic build, the site told me to go with XS. I went with my regular size S and it worked well. The bibs are a bit snug, especially while putting them on, but the compression is actually an added bonus for the legs. Especially in the quad area, where there is a horizontal seam running through. The cargo pocket is a great bonus for extra storage.”
