The boxer is made of knit mulberry silk. Very comfortable and very well fitted. You almost don't feel it thought out a day of wearing. Knitted silk fabric is more lightweight, breathable, soft, and comfortable, super better for lingerie, boxers, brief, etc.
4 Sizes, please check on the size guide( These are Asia sizes). If you are not sure about the size, please message me before ordering, we're glad to help.
