I'm a big guy (as in big, not tall though. 5'7") but my hands aren't huge, so I'm thinking large. Will a large set of Evergels fit snug or loosely? Will they fit inside 16 oz Everlast gloves?
What's the best place to order gloves from?
Yes, they should fit pretty snug, I bought a pair myself a pair at size large and I liked them, and yes, they fit nicely inside 16 oz. gloves, which is what I used to hit my heavy bag with. They can serve as an ideal replacement for hand wraps. But now I really just mess with wraps and lighter ounce bag gloves.
Altogether though, I think though the best place to ask questions like this is in the 'Training and Nutrition' forum. Just my opinion.
Regardless, best of luck.
