Hello, First of all, thank you for your interest in our product. Our products are made from a premium quality fabric blend of 47% Modal, 47% Cotton, and 6% Elastane. Modal-a natural fiber obtained from beech wood, provides high air permeability, does not cause sweating and quickly removes moisture. Cotton gives its final form to modal. The elastane content gives the product flexibility and freedom of movement. Thanks to this special blend, our product has an extremely soft, light, and comfortable texture. We wish you pleasant shopping.
