RunnersHeart unisex short-sleeve T-shirt
The RunnersHeart technical T-shirt, short-sleeve for men, has an exclusive design produced by digital sublimation so that the fabric fully retains its technical properties of breathability, lightness, softness and fast drying.
The RunnersHeart running T-shirt is made with the premium 100% recycled Infini_Tech fabric. This fabric is made with polyester yarn from recycled plastic bottles and offers maximum breathability and lightness, with the added value of contributing to sustainability. As a curiosity, making one medium-size T-shirt recycles around 20 plastic bottles of 500ml.
It is available in a men’s, a women’s and a kids’ fit to offer the best possible fit for every athlete’s body. Like all 42K technical running T-shirts it has anti-chafe flat seams, as well as the “Soft-Light” anti-chafe treatment.
In addition, this T-shirt has the “Dry Tec +” quick-drying treatment, which helps moisture evacuation. To keep the colours bright and true, the “DC4” colour-fixing treatment is used, which stops them losing vividness with washing and over time.
