OMM Dyno Shorts Men'sDescription Running shorts are among the hardest bits of kit to get right and its certainly difficult to find a pair that works for you. We think the all new Dyno manages it. Removing bulky stitch lines, shaping the fabric panels and liner to create a comfortable and supportive short without extra weight or excess fabric has been a long standing challenge but here they are. The all new bonded construction of the Dyno Short provides unrivalled comfort.
