I know Cathe no longer sells Cathe-branded fitness accessories (sad face) but I wonder if anyone knows the brand of gloves used in STS - the kind with the sand weight pouches inside the top of the glove. I have a pair now I use for boxing, but the sand bag on one of the 1# weights has torn and sand is flying everywhere. Plus, those gloves I have an open palm. It looks like the gloves Cathe used in STS had a padded palm, which is preferred for the heavier weight lifting. Any recommendations? Thanks.
