Oozing quality, the Sonic’s construction and fit are at Assos level. The large, breathable side panels have more elastic resistance than similar ones on other shorts too. The minimal pad is highly sculpted, with different depths and densities all positioned perfectly for supreme comfort.
The bib section is close fitting and brilliantly formed too, and material is removed where it isn’t needed, creating channels that improve airflow. The light mesh of the bib is also highly breathable. We’ve found it difficult to fault the Xenons – aside from the high price.
