I was between sizes and chose to go up a size for the larger pouch, as recommended by the C-IN2 support team. The pouch has enough room but still provides support. They are soft as butter and seem like they will last for years. Extremely comfortable. The style and cut complement the body and make you look fantastic. These are my go-to daily wear. I purchased 28 pairs of both the grey and white briefs, so yeah, I'm addicted.
