Australian Oilskin Golf Ball and Tees is made of Australian oilskin which is weatherproof. The main compartment can fit at least twenty golf balls and the YKK zipper will keep them contained within, instead of bouncing around uncomfortably. The smaller front compartment is zippered as well and can fit a whole lot of tees—though you could wack in your phone or keys instead if you so fancied. The bag also features a sturdy metal clip! Clip it to your belt, golf bag, etc., and you won’t have to worry about your balls being hard to get to.
