A collection pursuing a high-quality wardrobe, designed by Artistic Director Christophe Lemaire and his design team, in collaboration with the Paris R&D center, which gathers information on fashion and new materials from around the world. - Uses HEATTECH with heat generation, heat retention, antibacterial, stretch, and moisture-wicking functions. - The outer is made of cotton, and the back thread uses HEATTECH functional yarn, creating a texture that doesn't look like an inner layer. - A long-sleeved HEATTECH T-shirt that can be worn not only as an inner layer but also as an outer layer. - Inspired by vintage military underwear. - Design points include a wide crew neck design with a high neckline and slightly longer ribbed cuffs.
