The Xenons are made from a Lycra-weight material with an abrasion-resistant inside leg/seat area.
The bib uses only a small mesh panel so in use it’s not as breathable as some but the straps are wide enough to spread the load comfortably. The multi-panel construction makes for a superb anatomic shape and all the seams are flat and well positioned. Gel foam sections in the excellent multi-thickness, highly elastic pad prevent long-ride numbness while reflective trim adds to your visibility. Order with care though: our size large was by far the smallest on test.
