Core Trunks are great!
"I really like the Core Trunks underwear in organic cotton. They are very comfortable and breathable. The length is just right. They look great and I think they’re great quality. These are my new favorites."
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."
