Bad pockets
Like the material, fit, and belt. But those pockets…. Did anybody test them? Put anything in them, phone, keys, etc. , it hangs low enough that it will rub your thigh as you move. I would return the shorts if I could, and only recommend these if you are going to wear spandex or chamois that goes to your knee all the time.

Pretty good
These shorts are comfortable and lightweight but could seriously use some grippers along the back of the waistband. when wearing bibs these shorts are sliding around quite a bit.

taille à revoir
Super short pour le vélo ou même la détente. Mais. . . Il n'y a plus les tailles intermédiaires (31). Du coup le 30 est serré à la taille, le 32 trop loose au bassin. Dommage. . .
