Hmmmm. Strange. I'm 6ft 1in / 195lbs and usually wear a size 34-36 in jeans. I bought the XL because others said they ran small. I'm not sure what they are for. They are definitely not suitable for training. There is no "package". This is pretty close to how I imagine panties. There's no place for anything. Without trying to humbly brag, your genitals just have nowhere to go. Super low cut too. I went to the top during training. This is the most confusing underwear I've ever tried on. If you plan on wearing a mug, change your plans. This is not a sport promotion. These are trendy panties.
