Bought the Endura Burner shorts for mountain biking on flat, hard pack trails where the riding is rough and bumpy and they worked out great! Construction quality is excellent, they have good padding in the seat area and fit comfortably. Glad I bought these rather than change my seat. Essentially these are baggy mountain bike shorts with built-in padded undershorts underneath. The outer shorts are water repellant and the form-fitting (spandex or lycra?) inner liner/shorts are moisture wicking. Having 3 zippered pockets is great too, very functional along with great style. Love these UK-made shorts, worth every penny.
