42K has strengthened its line of custom sports apparel for athletics clubs, sports teams, and groups. The CUSTOM 42K line makes any desired design a reality thanks to the advantages of digital sublimation and post-printing manufacturing.
The CUSTOM 42K line offers an extensive catalog of 100% custom technical garments to meet the needs of sports clubs and teams, as well as groups that want top-quality custom sports apparel.
Any club, team, or group can wear their custom sports apparel with an exclusive design, with complete freedom to choose colors or insert logos, with the option to select seam colors and even individual customizations such as name, number, nickname…
Additionally, for this 100% custom apparel line, different premium fabrics are offered, notably the 100% recycled INFINI_TECH fabric, which is made with polyester yarn obtained entirely from recycling used plastic bottles; the polyester yarn for this fabric is produced from small pellets called ‘granza‘, which is the recycled material into which used plastic bottles are transformed.
Naturally, the INFINI_TECH technical fabric guarantees exceptional lightness and breathability for manufacturing t-shirts designed for running and athletics.

Custom sports apparel with unique and exclusive designs
The demand for custom sports apparel, with unique and exclusive designs, is growing because it allows for more effective visibility for brands and sponsors.
The CUSTOM 42K line of custom sports apparel is designed from scratch, starting from a blank canvas on which our Design team can unleash their creativity or apply any client request. This allows us to bring to life any color, design, gradient, shadow, logo, or graphic motif that can be applied to different parts of the sports garment.

What distinguishes the CUSTOM 42K line is, on one hand, the extensive catalog of technical garments available for men and women; and on the other hand, the infinite possibilities for customization thanks to the advantages of full-color digital sublimation and post-printing manufacturing.
Extensive catalog of 100% custom technical garments
The new CUSTOM 42K catalog of custom sports apparel includes numerous technical garments, for both men and women, that can be fully customized.
Among the garments with a men’s pattern, we find short-sleeve, long-sleeve, tank top, and sleeveless technical t-shirts. Men’s garments are completed with running shorts and short tights. To learn more, visit the men’s pattern garments section.

Women’s pattern garments, in addition to short-sleeve, long-sleeve, and tank tops, also include running tops, short tights, and athletics neck gaiters. To learn more, visit the women’s pattern garments section.

Unisex garments of great utility and versatility are also offered, such as a multisport technical sweatshirt and tracksuit pants. To learn more, visit the unisex pattern garments section.


To meet the demands and needs of sports clubs with children’s categories, an extensive range of sizes is available for most technical garments in the 42K custom sports apparel catalog. The manufacturing possibilities we offer include sizes ranging from 4 years old up to XXL for men and XL for women.

If you have any questions about the different technical garments we offer, you can use the form on our website, and our CUSTOM department will provide detailed information.
Textile sublimation and post-printing manufacturing, innovation for custom sports apparel
Textile sublimation is an innovative digital printing technique on fabric. This technique, which allows for the creation of 100% custom technical garments without color restrictions, ensures the permanence of the design (logos, colors, gradients, emblems…) as the colors are chemically fused with the fabric.

Once the image or computer-designed pattern is transferred, it integrates into the fabric and is absolutely imperceptible to the touch. And in addition to leaving no residue, it does not increase the weight of the fabric and does not alter its breathability. This way, any custom technical garment made with sublimation retains all the softness, lightness, and breathability characteristics of the fabric.
Another advantage of sublimation for custom sports apparel is that it allows the use of the entire garment surface (with other techniques, customization areas are restricted to the chest and back), including sides, sleeves, collar, etc. And as we have already emphasized: without color restrictions.
The CUSTOM 42K Line offers three options for customizing technical garments
There are three different customization options within the CUSTOM 42K line.
- Option 1: Predesigned templates by 42K onto which logos, brands, or emblems sent by the client can be integrated. The colors of these templates can be adapted to the corporate image of each club, team, or group, but the design is unalterable.

- Option 2: Exclusive design by 42K. After the corresponding briefing with the client, the 42K Design team proposes an exclusive and original design for 100% custom sports apparel.



- Option 3: Exclusive design by the client. The 42K Design team provides the client with blank digital patterns of the technical garments so that the client can create the desired design.

Recommendations for maintaining 42K custom sports apparel in good condition
Custom sports apparel, like all other 42K technical garments, requires special care to extend its lifespan. On our blog, you can find an article titled How to wash sports apparel to make it last longer, where we offer a series of tips on how to wash sports apparel to prevent it from losing its technical characteristics of breathability, softness, or color vibrancy.
Following the advice we offer in that article will allow you to keep your custom sports apparel in good condition and prevent it from deteriorating prematurely, especially if you use it regularly. If you follow these care and cleaning recommendations, you will extend its lifespan and reduce the risk of unpleasant odors appearing.
However, if unpleasant odors appear in your custom sports apparel, we offer 3 tricks to eliminate bad odor in sports apparel that can help you get rid of the bad smell that sometimes appears in the technical garments we wear for running or going to the gym.
