If you work out with kettlebells, free weights, bar balls, dumbbells, pull down ropes or even medicine balls, you most likely use workout gloves. Over the years I have tried many different brands, but I have been lucky to get more than 2 or 3 months from any that I have tried.
Bionic brand gloves give a very nice grip when they are new, but they are relatively thin and in my experience, break down a little too easily.
My new favorite are weightlifting gloves made by GoFit, called GoFit DTAC.
I got these at Buy.com for about $22 (including shipping) and I have been using them for just over 2 months. I am very impressed with both the grip and the durability. I put a lot of stress on my gloves, using them for kettlebells, weight bench training, rope pulldowns and even pushups. So far these are the best gloves I have every used.
The gloves come with an exercise CD that is fairly generic but if you are looking for durable, functional workout gloves, give the GoFit DTAC gloves a try.
