The 42K CUSTOM LINE T-shirt in Regular fabric lets you create fully customised designs, with no creative limits.
Thanks to digital sublimation and post-printing manufacture, every area of the garment —front, back, sleeves and neck— can be customised with any combination of colours, gradients, logos, text or graphic motifs.
This customisation system integrates the design directly into the fabric without altering its technical properties, keeping the T-shirt's softness, breathability and comfort intact.
The garment is made with Neo-Tec 100% recycled fabric, developed from polyester yarn obtained by recycling used plastic bottles.
Its 140 g/m² weight provides an excellent balance between comfort, technical performance and resistance, offering greater durability even under intensive use.
A 100% recycled fabric that combines high sports performance with the added value of contributing to more sustainable production.
More features:
- Adult and children's sizing.
- Extra-large sizes (3XL, 4XL, 5XL) available only in the men's pattern.
- Flat seams and printed anti-chafing label.
- Set-in sleeve.
- Ergonomic front pattern with longer back rear panel.
There are 3 customisation options for these sports T-shirts:

- Exclusive design created by the customer.
Warning:
Using backpacks, hydration vests, gym bags, waist belts or race number belts and any other accessory over the T-shirt may wear out or damage the fabric because of the abrasion and friction they cause. The fabrics of our T-shirts offer extraordinary performance thanks to their breathability, lightness and softness. Our fabrics receive state-of-the-art treatments to guarantee quick drying, softness to avoid irritation and colour fastness. Our commitment as a brand is to guarantee technical garments of the highest quality and performance for running and other sports where there is no risk of snagging, pulling, tearing, friction or abrasion.
