Dynamic Discs Grandmas Dirt Bags - Standard D's
About Grandmas Dirt Bags When Adam Searle and Jeremy Rusco saw dirt bags for the first time at an event, Adam said, "I bet Grandma could make these." She hand-sewed 200 for Dynamic Discs over 10 years ago, and she's been making them ever since. If you've used one of these to get a solid grip on your disc, you can thank Grandma for it! Dynamic Discs "dirt bag" contains a mix of rocks that, when rubbed together, create a "dynamic dust" that feels similar to rosin. Features: Super absorbent and easy to carry. Retain their drying ability for longer than other similar products. Unlike other products out there, if these happen to get wet, they will dry out and be usable again in future rounds.
