STELLAR: a collection made with 100% recycled fabric<\/strong><\/h2>\nThe starting point for the STELLAR collection is its Neo-Tec fabric<\/strong>, made from 100% recycled polyester. Sustainability is one of 42K\u2019s strategic pillars, and more and more collections incorporate fabrics that focus on recycling and the lowest possible environmental impact. <\/p>\n![\"Stellar:](\"https:\/\/42krunning.com\/wp-content\/uploads\/2025\/10\/camiseta-running-manga-larga-stellar-42k-00008.jpg\")
<\/a>STELLAR Antares<\/figcaption><\/figure>\nBut choosing the fabric isn\u2019t only about sustainability\u2014it\u2019s also technical. Neo-Tec stands out for its soft feel against the skin<\/strong> and its special 140 g\/m\u00b2 weight<\/strong>, making it an ideal fabric for long-sleeve tops or winter running tops. This higher weight adds extra durability and, at the same time, more warmth\u2014making the difference on training days when temperatures are lower at dawn or as evening falls. <\/p>\nA collection inspired by the stars<\/strong><\/h3>\nThe STELLAR collection<\/a> is inspired by four great stars<\/strong> in our sky: Naos, Vega, Antares <\/strong>and Alpha Orionis<\/strong>. The universe has served as an aesthetic and conceptual guide for the development of these designs. <\/p>\nAs a tribute, each top features on one sleeve the star\u2019s name, its astronomical coordinates, and a depiction of the constellation it belongs to<\/strong>. A detail that gives each garment its own identity and strengthens the bond between the runner and that infinite universe that opens above their head on every night training session or outdoor run. <\/p>\nThe result is four exclusive models<\/strong>, with bold, original colour combinations that convey strength, energy, and movement.<\/p>\n![\"STELLAR:](\"https:\/\/42krunning.com\/wp-content\/uploads\/2025\/10\/camiseta-running-manga-larga-stellar-42k-00029.jpg\")
<\/a>STELLAR Vega<\/figcaption><\/figure>\nThe four STELLAR models: Naos, Vega, Antares, and Alpha Orionis<\/strong><\/h3>\nEach star inspires a unique design within the collection.<\/p>\n
\n- Naos<\/strong><\/a>: petrol blue and vivid orange.
\nNaos is one of the hottest stars known, and its design pays tribute to that extreme temperature. Petrol blue<\/strong> dominates the overall look, contrasted with a vivid orange<\/strong> that conveys energy and vitality. Perfect for those looking for an eye-catching top that still feels balanced. <\/li>\n- Vega<\/strong><\/a>: black and neon blue.
\nElegance and modernity in one design. Deep black<\/strong> sets the base of the top, while the neon-blue details<\/strong> evoke Vega\u2019s brightness, one of the most brilliant stars in the night sky. Ideal for runners looking for a understated style with personality. <\/li>\n- Antares<\/strong><\/a>: burgundy and fiery oranges.
\nInspired by the reddish hue of this supergiant, Antares combines an intense burgundy<\/strong> with fiery orange accents<\/strong>, creating a vibrant, warm effect. A piece full of character that reflects the passion of those who put all their energy into every training session. <\/li>\n- Alpha Orionis<\/strong><\/a>: purple with violets, pinks, and oranges.
\nAlso known as Betelgeuse, Alpha Orionis is the most famous red supergiant in the Orion constellation. Its top combines dark purple<\/strong> with a palette of violets, pinks, and oranges<\/strong> that adds rich colour and originality. A highly visual, artistic piece for those who want to stand out. <\/li>\n<\/ul>\nUnisex fit and versatility<\/strong><\/h4>\nThe STELLAR collection uses the unisex pattern<\/strong> that debuted with the VORTEX Winter<\/a>. This pattern includes side vents<\/strong>, designed to improve range of motion and aid ventilation. Its ergonomic design adapts comfortably to both men and women, offering a standard fit<\/strong> that ensures the perfect balance between comfort and performance<\/strong>. <\/p>\n![\"STELLAR:](\"https:\/\/42krunning.com\/wp-content\/uploads\/2025\/10\/camiseta-running-manga-larga-stellar-42k-00011.jpg\")
<\/a>STELLAR Naos<\/figcaption><\/figure>\nThese are technical tops designed mainly for running<\/strong> and trail running<\/strong>, but their versatility also makes them an excellent option for trekking, Nordic walking<\/strong>, or a wide range of outdoor activities<\/strong> where you need to maintain a balanced body temperature and have a lightweight, breathable, durable garment.<\/p>\nTechnologies that make the difference<\/strong><\/h4>\nIn addition to Neo-Tec fabric, STELLAR tops incorporate three exclusive technologies that ensure performance even under intensive use:<\/p>\n
\n- DC4-Long Life Run<\/strong>: ensures colours keep their original intensity, even after multiple washes and long training sessions in the sun.<\/li>\n
- DRY-TEC+<\/strong>: promotes quick drying, keeping the skin as dry as possible even during high-intensity efforts.<\/li>\n
- SOFT-LIGHT<\/strong>: adds extra softness to the fabric, preventing chafing and discomfort during movement.<\/li>\n<\/ul>\n
Thanks to these technologies, the STELLAR collection becomes a reliable ally for those who train several times a week and want a garment that combines durability, comfort, and aesthetics.<\/p>\n![\"\"](\"https:\/\/42krunning.com\/wp-content\/uploads\/2025\/10\/camiseta-running-manga-larga-stellar-42k-00038.jpg\")
