As a decades-long gym rat, the only weightlifting outfits I wear are Everlast. Period. Full stop. Forget the obscenely expensive designer duds. I have invested a few grand in Everlast. And they last seemingly forever. I buy mine at Sears and Kmart. Best selection and prices.
I have boxing gloves from here as well as a punching bag. Everlast is really made to last, I also have a few pairs of yoga pants from them that I've had for a good minute still in great condition.
Those are good products because they are still made since 1910 a year to now. Also, they are to add apparel too.
