The FlashDry fabric actually works — I finished a humid 5-miler and these were dry before I even got to my car. The 7-inch length hits right above the knee without riding up, which is exactly what I wanted.
Took these out for a 10-mile trail run and the FlashDry fabric actually kept me dry even on the humid climbs. The 7" inseam hits right above the knee, no riding up or chafing. Easily my go-to shorts now.
