I bought quite some thongs and g-strings from Cover Male and I'm very satisfied with the product.
The models look like the Joe Snyder collection and the quality of fabric and sewing is the same if not better. The fit is good, some thong models are a little small in the front. If the front was a half inch wider it would have been perfect. But with walking, nobody will notice. The pricing is very interesting, so between $10 and $20. That means 1/2 to 2/3 of Joe Snyders prices.
It is labeled as underwear but it is perfect for the beach too. The only negative is the printing of the labelcontent at the inside of the pouch. It is visible as tiny ridges through the thin fabric. I guess printing is cheaper as they also print a big CM at the outside of the pouch.
