These are the ones I have. The palms are just a layer of fabric with silicone grip on them. I mostly wear them to keep my calluses from getting too bad and for a little extra confidence on the TRX.

I've also found that wearing a silicone ring instead of my wedding and engagement rings so I don't have the paranoia of "OMG where are my rings?!" and they get in the way less than my metal rings.
