This singlet is made from a variation of our lightest fabric to date, a 140 gsm single jersey, pre-washed to keep the shape after wearing and to maximize comfort. The body fabric is highly breathable and soft, tested and enhanced to prevent chafing during runs. The cut is specifically made to minimize fabric and stitches, while maintaining a classic look, that will look great during runs in any circumstance. On both sides, 3 cm slits have been added for optimum movement and ventilation during workouts. Composition Fabric: 100% TENCEL™ Lyocell. Sewing threads: 100% TENCEL™ Lyocell. Prints: Water based ink transfers. Dyes: Bluesign® certified. Wash Instructions Wash at 30 degrees. Don’t tumble dry. Don’t use bleach. Iron with medium heat. Wash with the same colors. Fabrics from natural origin can shrink a little bit after washing them, which we have taken into account with our sizing. Sizing This singlet has a regular fit. If you usually have size M with your singlets, you should also pick size M with this one. If you prefer a tighter fit, pick one size smaller. Our model is 190 cm / 6'3" and is wearing size L.
