The CanDo balls have a non-slip surface that is ribbed for extra security. The balls may be "under" inflated to give a soft, mushy feel or fully inflated for a firm, bouncy feel.
Available in various color-coded sizes and 3 styles: standard balls have a 300 lb capacity, ABS Extra Thick have a 450 lb - 600 lb capacity range, and Super-Duty Super Thick balls have a 600 lb capacity.
