DEEP Collection, the new definition of a T-shirt running

by Paco Amoros

En 42K we have been for years betting on textile innovation as a driving force to continue improving our technical garment collections. We listen to ourredpray and heartredNow, we test fabrics, develop patterns and challenge ourselves to surpass ourselves with the launch of each new collection of t-shirts for running.

This is how he was born DEEP, a collection designed to take performance one step further, with details never seen in our catalogue and a design combination, technology y comfort which makes it our most advanced proposal for demanding training and competitions.

DEEP collection, with bidirectional elasticity and laser microperforations

DEEP stands for the determination of 42K to continue running towards the future and setting the pace of technical innovation in the world of runningThis new collection of short-sleeved t-shirts, specially designed for running, represents a leap forward in terms of performance, comfort and design thanks to two technical innovations: a fabric with bidirectional elasticity that ensures a increased range of motion already an area of laser microperforations to guarantee a Excellent breathability.

The DEEP collection has a standard relaxed fit (relaxed fit) offering a excellent anatomical comfort to athletes who push themselves to the limit in their training and competitions.

Elastter, freedom of movement without restrictions

The heart of the DEEP collection is Elastter, the most advanced technical fabric developed to date by 42K. It is a combination of 88% recycled polyester and 12% spandex/Elastane (fiber characterized by its ability to stretch and return to its original shape without deforming), which results in a ultralight material, with excellent adaptability and exceptional technical performance.

DEEP collection with bi-directional stretch — The DEEP collection is made with Elastter fabric, which is characterized by its two-way elasticity.

Elastter offers bidirectional elasticity which allows the fabric to follow the body's natural movement without resistance. This ability to stretch in two directions ensures total freedom in every stride, at every turn of the course, at every change of pace. Whether on a long run or a short, high-intensity series, the fabric effortlessly adapts to the athlete's body, redreducing friction and improving overall comfort.

But if something defines Elastter, besides its flexibility, it is its extraordinary softness to the touchThe fabric feels light and silky against the skin, providing a second-skin feel that makes all the difference during extended sessions. This softness provides comfort and also helps to prevent chafing even in conditions of high humidity or heat.

DEEP T-shirts, thanks to the Elastter fabric, provide a feeling of total freedom, fluidity and lightness, facilitating a more natural and comfortable running technique. If you'd like to learn more about Elastter fabric, here's a detailed article: “Elastter, new premium fabric from 42K".

We affirm, without fear of disappointing any heartredor or corredNow, the DEEP collection offers total freedom of movement, without restrictions, thanks to the combination of the Elastter fabric and the cut relaxed fit.

If you'd like to see each APEX model, you can find them in our online store: APEX collection.

Laser microperforations, innovation to improve breathability

The great technical innovation of the DEEP collection is the microperforation areas made with laser that have been strategically located in the sides of the front of the shirt.

This detail, which represents a qualitative leap in textile manufacturing technology 42K, significantly improves the breathability of DEEP T-shirts. The microperforations increase ventilation capacity right where the body needs it most during the race, promoting thermal regulation and contributing a continuous feeling of freshness.

Thanks to this innovation, the DEEP collection becomes an ideal choice for demanding training in high temperatures and to competitions in the summer months When heat becomes an athlete's enemy. The combination of ultralight, breathable fabric and an additional ventilation system makes these T-shirts indispensable allies for running without limits, even on the hottest days of the year.

A marine-inspired collection

The name DEEP is inspired by the depths of the ocean, its apparent calm, its inner energy, and its extraordinary biodiversity. This connection with the marine universe is reflected in the color palette selected for the three models that make up the collection:

DEEP Dark Blue: Sobriety and elegance with dark blue tones, elegant and intense, evoking the depth of the deepest waters and conveying calm and determination.

DEEP Mint: Visual freshness for those seeking a more vibrant and contemporary design, with aquamarine tones reminiscent of the light that passes through tropical reefs.

DEEP White: a clean and minimalist proposal, inspired by the delicate whiteness of the coraleg.

Each model is available with specific pattern for corredory and corredNow, adapting the adjustments to the body of each type of athlete. The court relaxed fit (relaxed fit), combined with the elasticity of the fabric, ensures a comfortable and technical fit that favors movement without restrictions or discomfort.

Safety on the move: reflective detail on the back

We know that many heartsredpray and heartredSometimes they train early in the day or at dusk, especially in the hottest months of the year to escape high temperatures, when visibility can be limited.

DEEP t-shirts incorporate a small reflective band on the back, which acts as extra visibility element in low-light conditions. This simple but important addition enhances safety without altering the garment's clean, sophisticated design.

Technology at the service of performance

In addition to its latest generation fabric and the incorporation of laser microperforations, DEEP t-shirts have the three most advanced technologies in our catalog To ensure maximum performance during use:

Soft-Light: This technology ensures a soft and delicate touch, avoiding chafing even during long sessions or under adverse weather conditions.
Dry-Tec +: system of fast dry which accelerates the evaporation of sweat and helps maintain Dry Skin and regulated body temperature.
DC4 – Long Life Run: special treatment to guarantee a high color durability, even after multiple washes and intensive use.

A proposal designed for high performance… and much more

DEEP is not only a technically impeccable collection, also represents an aesthetic evolution within the catalogue of 42KThe color palette, sublimated designs, and reflective back panel make each tee stand out in style without sacrificing functionality.

This collection is designed for demanding runners, who are looking for performance without sacrificing comfort or design. But it is also a perfect choice for regular training, medium and long distance tests, or even for functional activities al airand free or in a room where freedom of movement and ventilation are crucial.

Commitment to Sustainability

En 42K We continue to strengthen our commitment to more responsible production. That's why the Elastter fabric used to make the DEEP collection uses 88% recycled polyester, thus contributing to a smaller environmental footprint without sacrificing technical performance. We believe that innovation should not be at odds with environmental commitment, and DEEP is a clear example of this.

“We are especially proud to present the DEEP collection, not only for its technological innovation and design, but because it represents everything we aim to offer as a brand: sustainable garments, with high technical performance and designed to accompany athletes in their most demanding challenges. DEEP is, without a doubt, a step forward for 42K", explains Guillermo Peñalver, manager of 42K.

The commitment to sustainability of 42K It is unequivocal and that is why since 2019 we have been working on the development of fully recycled technical fabrics or with a high percentage of recycling. Infini_Tech It was our first 100% recycled fabric, made with polyester thread obtained from the recycling of plastic bottles and with which different highly successful collections have been created, such as Elements, Ozone, Wave o PangeaWe also have the fabric TriActive, also 100% recycled and with which the collection is made Motion.

DEEP represents a new era for technical t-shirts running en 42K. A collection born from hard work, active listening, and research, and prepared to accompany you where the real effort begins: with every mile left to travel.
