Frequently Asked Questions

What does “seamless” construction actually mean? Seamless underwear is knitted in a single continuous process rather than cut and sewn from panels. This eliminates the raised seam edges that create friction and pressure points during movement — particularly noticeable during running, cycling, or any activity involving repetitive leg motion.

How does milk-silk polyester differ from standard polyester? Milk-silk polyester has a finer, softer texture than standard polyester due to its microfiber construction. It feels smoother against skin, has better moisture-wicking properties, and dries faster — making it more suitable for athletic use than regular polyester blends.

Are the sizes L–4XL true to Western sizing? These follow Asian sizing standards, which typically run 1–2 sizes smaller than US/EU equivalents. If you normally wear a US Large, select XL here. When in doubt, size up for a more comfortable fit.
