Sticky Mats

Hi all,
I’m hoping someone can help with this question. Is there a brand of yoga mat that is especially “sticky,” even with sweaty palms and feet. I’ve been using the gym’s mats, and I find myself sliding in the first minutes. I’ve looked online for mats, but there’s a vast array of them, it seems. Any information you can offer would be greatly appreciated!
Thanks!
