Save your money, avoid C-in2, buy something well-made

Uncomfortable! Poor quality! Bad Customer Service! Nice box/advertising!I purchased 3 of these (different colors), never having owned this brand. I purchased from another online retailer, not Amazon. One had a tag that read "Medium" which didn't match the size on the box or the size ordered, which was "Large". Upon calling the online retailer all of their stock in the color "gray" was the same situation. Returned it and received a replacement pair, size "Large", which was significantly bigger than either of the other 2 pair which were supposed to be size "Large". I called C-in2 to express my dissatisfaction with the initial stock mix-up of all gray pair, received no response.Lastly, the "sling" advertised, sounds better in theory than it is. After a couple of minutes the sling gets uncomfortable, feels like a paper cut.
