Fairly large can fit a lot of bottles Not so much to hold my wine, but to hold my wine wine glasses. We strapped it to a pull-up bar and added a few plates and it perfect for rows, tricep exercises, shoulder work, and chest. Happy with my choice Unfortunately, this is not a good product. Just got the PRO rack and am slowly adding on accessories. Very durable, soft, and cushiony. Supporting micro SD card can be great for storing songs. I feel much more organized now. Unfortunately, will not hold larger base wine bottles except on top two open notches.
