Good quality as usual. The

"Good quality as usual. The fabric is comfortable and pleasantly soft. The fit is also good, and the elastic band doesn't dig in. I recomend: If you are between sizes, it is advisable to choose the larger size. The colors are a little more subtle than they appear in the pictures. But I like it. I've bought underwear from Organic Basics several times before and I think this line is one of the best. I'll definitely buy it again."
