Wash the T-shirt at a maximum temperature of 30°C (86°F). For best results, we recommend washing it inside out with similar colours.
The T-shirt is made from a soft and comfortable blend of: 48% Cotton 48% Modal 4% Elastane The cotton and modal provide a soft, breathable feel, while the elastane adds stretch and helps the T-shirt retain its shape.
We recommend allowing it to air dry to help maintain its shape and softness.
Yes. You can iron the T-shirt at a low temperature (maximum 110°C / 230°F).
Our discreet sweat patches are specially designed to absorb and trap sweat before it reaches the outside of your shirt. The multi-layer construction holds moisture in the underarm area and helps it evaporate gradually, keeping your outer clothing looking dry and helping to prevent visible sweat stains. The patches are built directly into the underarm area, so they stay comfortable and discreet while you wear them.
