These back cinch pockets are the perfect answer for where to put your phone while you ride! They fit securely on your back cinch and open and close with a strong Velcro so you don’t have to mess with a buckle or snap while you’re riding! The XL will fit all phones and may also fit a few other necessities like your keys or sunglasses. Please note that they need a D-ring setup to attach properly, they will not work for cinches that loop through the saddle skirt without a D-ring.
