These Mitts from Elite Sports (https://www.elitesports.com/) are a very decent set of hand mitts for the price. They are very economical at $29.99 and seem to be well put together. They come in White, Black and Red and are a good size for both your hand and for striking. 

The super light-weight feel gives you a more natural set up while you are working with someone, your hands and arms do not get tired quickly. The light weight nature makes these great for packing in your backpack and taking along to the gym with you. These mitts are constructed out of PU leather, while not being real, this stuff seems to last a long time, and help keep the costs of production down considerably. I have other sets of mitts that are real leather and while they do last a very long time, they are quite heavy after a long session. 

After a few rounds of use, I would recommend these to anyone looking to add a few sets of mitts to your gym or just as your own personal set to carry around with you.
