Army
The ARMY technical T-shirt collection takes its inspiration from military camouflage patterns and offers a powerful, competitive identity for running through a contemporary, technical design.
Made with Dynair fabric (100% recycled polyester), it offers an optimal combination of lightness, breathability and durability. This very light fabric favours ventilation and the rapid evacuation of sweat, helping to keep the body dry both in intense training and in competition.
The print is produced by digital sublimation on the back, shoulders and sleeves, which guarantees the design is fully integrated into the fabric without adding weight or stiffness to the garment. The result is a very light (100 gsm) technical T-shirt, resistant to wear and with an aesthetic full of character.
Available in five colour combinations:
- ARMY Snow
- ARMY Desert Sand
- ARMY Black/Tan
- ARMY Viper Green
- ARMY Navy Blue
The ARMY collection incorporates a specific pattern for men and women, guaranteeing an adapted fit that favours freedom of movement and comfort while running.
ARMY T-shirts have flat invisible seams (with no ridges or bulk), which brings benefits to running garments, especially in middle- and long-distance training and competition. Flat seams minimise the risk of chafing (irritation in sensitive areas is avoided) and ensure greater comfort while running.
