The Merz b. Schwanen THERMAL01 Diamond-Patterned Cotton Thermal is a classic long-sleeve thermal with an authentic vintage-inspired feel. Cut in a classic fit, it can be worn on its own or layered through colder days, bringing a retro look into a modern everyday staple.
Crafted from 365g/qm, or 11oz, diamond-structured thermal jersey in 100% organic cotton, the fabric has been carefully recreated from a true vintage piece for timeless texture and character. A crew neck, sleeve cuffs, triangle inserts under the arms and swan loop label at the hem complete the design with thoughtful Merz b. Schwanen detail. Made in Portugal, it reflects the brand’s focus on comfort, quality and enduring essentials.
