BottlePro was designed for bottles that are approximately 3.5″ to 3.8″ across and have straight-vertical walls. This includes but not limited to: Hydro Flasks (32/40 Ounce) Nalgenes (32/48 Ounce) YETI Rambler Bottles (36 Ounce) Klean Kanteens (32/40 Ounce) And many other large bottles BottlePro does NOT work well with tumbler-style bottles that get smaller towards the bottom. Also is too small for 14oz YETI mugs. IMPORTANT, PLEASE READ! There are thousands of possible cup holder and bottle combinations, and BottlePro will not work for every single situation. If BottlePro doesn’t work well for you, please contact us directly for an easy hassle-free refund.

• Soft-fit foam sleeve included with every order to better fit in-between cup holder sizes securely.
• Slot in the side to accommodate mug handles.
