T-shirt X-Bionic INYT00S19M Round neckline Short sleeve Elastane 7% Polyamide 90% Polypropylene 3% (Men, Adult)

X-Bionic INYT00S19M is a men's functional T-shirt with a round neckline and short sleeves, made from a technical blend of 90% polyamide, 7% elastane and 3% polypropylene. Designed as a form-fitting base layer, the shirt provides stretch, durability and moisture-management properties for sports and active outdoor use. The garment is part of the X-BIONIC® INVENT® 4.0 LIGHT collection and incorporates the patented 3D Bionic Sphere® System to help regulate body climate during exercise, enabling faster drying and improved thermal comfort in warmer conditions.

Advantages

The fabric composition ensures a close fit with good elasticity and shape retention while polypropylene and polyamide fibres support rapid moisture transport and quick drying. The integrated 3D Bionic Sphere® System provides targeted ventilation and intelligent thermoregulation to reduce overheating during intense activity. The lightweight, thin structure minimizes bulk when worn as a base layer under other sports garments and supports unrestricted movement during running, cycling, trekking and gym training.

Suitable for

• Endurance running and interval training in warm to moderate temperatures
• Cycling and indoor spinning sessions
• Hiking, trekking and fast-paced outdoor activities
• Gym workouts and cross-training as a technical base layer

How to use

Wear the T-shirt directly against the skin as a technical base layer to maximise moisture transport and thermoregulation. Use it for high-intensity training or prolonged activity in warm conditions to benefit from the 3D Bionic Sphere® System’s cooling function. Combine the shirt with outer layers as required for insulation or weather protection; remove outer layers during intense efforts to allow the fabric to manage sweat and body heat effectively.

Usage recommendations

For optimal performance, select a size that provides a close fit without restricting movement and follow garment care instructions on the label. Machine wash at recommended temperature, avoid fabric softeners that reduce moisture-wicking, and dry flat or tumble dry low to preserve fabric elasticity and the functional structure.
