Which fabrics are best for men’s undershirts?
Cotton, MicroModal®, performance fibres or merino wool? The choice of fabric directly affects comfort, temperature regulation and how discreet an undershirt appears under a dress shirt.
Depending on the use—daily business wear, travel or warm temperatures—some fabrics are more suitable than others. Some feel particularly soft on the skin, while others are designed to regulate moisture or remain completely invisible under a dress shirt.
