I never thought ventilation meant ventilation holes at the top and bottom! If you want to clean your mouthguard or retainers and use them on the go these are perfect. They are inexpensive and relatively durable. I bought them for my grandson to keep his servants in the water during the day :(. So they are not suitable for my purpose.
