Men's Silk & Cashmere Seamless Crew Neck Thermal Underwear Set

This thermal underwear set features a seamless crew neck design that fits the neckline without constriction or exposure, easily layering under any clothing for invisible warmth without bulk. Infused with cashmere and mulberry silk, the outer layer is delicate and skin-friendly, while the inner layer is fluffy and soft, providing efficient heat retention and skin-nourishing benefits, along with breathability and moisture-wicking to avoid stuffiness in autumn and winter.
The top is a long-sleeve slim-fit style with seamless cutting to reduce friction. The matching pants are made of the same fabric, with a high-elastic waistband that fits the waist and abdomen without tightness, and 360° high elasticity adapts to all body movements. The simple solid-color design is soft and comfortable, ideal for daily warmth, home wear or layering in autumn and winter.
