This breton shirt is made of high quality long-staple cotton as raw material, and is made of relatively excellent 80 counts double-strand strong-twist cotton yarn, which is fully knitted. Strong twist yarn has a refreshing texture similar to linen, but is more comfortable and skin-friendly than linen. At the same time, the yarn with a count of up to 80 makes it feel more soft and straight, with a strong vertical feeling, and its strength and wear resistance are unmatched by ordinary cotton yarn. The cuffs and hem of the clothes are designed to be threaded for a more refined visual effect.
