Our mini saddle bags are a pouch that attaches to your rear cinch billet so your phone, keys, etc can ride with you! Mini saddle bag has dual points of attachment (leather loop and leather tie), so it stays put and won't flap around. You can easily and quickly remove the mini saddle bag to switch saddles (no tools required). Buckle keeps top flap closed securely. Pouch measures 5" wide x 7" tall (not including flap) and expands to about 1-1/2" wide. It will easily fit all iPhone models (Plus and Max included) and similarly sized phones with room to spare so you can throw in your keys or other small item. Please note: your saddle must have a rear cinch billet to attach this bag. Refer to example photo showing one of these bags on a saddle.
