A versatile proposal to keep adding kilometres first thing in the morning, at dusk or during the mid-season months.<\/p>\n<h2>IGNITE, light thermal protection for running in cool temperatures<\/h2>\n<p>The IGNITE long-sleeve T-shirts are made from <strong>Neo-Tec<\/strong>, a <strong>140 g\/m\u00b2<\/strong> technical fabric produced with <strong>100 % recycled polyester<\/strong> yarn.<\/p>\n<p>Its <strong>special weight<\/strong> provides greater durability and extra protection against the cold, while keeping the essential properties of a technical running T-shirt:<\/p>\n<ul data-spread=\"false\">\n<li>Lightness.<\/li>\n<li>Breathability.<\/li>\n<li>Quick drying.<\/li>\n<li>Freedom of movement.<\/li>\n<li>Comfort during long training sessions.<\/li>\n<\/ul>\n<p>The result is a garment especially suited to those days when a short-sleeve T-shirt offers too little protection, but a thicker thermal layer would be too much.<\/p>\n<h3>A unisex pattern designed to move<\/h3>\n<p>The IGNITE collection uses the <strong>unisex pattern<\/strong> with side vents first seen in <a href=\"https:\/\/42krunning.com\/en\/collections\/?col=vortex-winter\" target=\"_blank\" rel=\"noopener\"><strong>VORTEX Winter<\/strong><\/a> and later used in the <a href=\"https:\/\/42krunning.com\/en\/collections\/?col=stellar\" target=\"_blank\" rel=\"noopener\"><strong>STELLAR<\/strong><\/a> collection, both also long-sleeve.<\/p>\n<figure id=\"attachment_89639\" aria-describedby=\"caption-attachment-89639\" style=\"width: 683px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/42krunning.com\/wp-content\/uploads\/2026\/07\/camiseta-hombre-ignite-gray-42k-03-1-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-89639 size-large\" src=\"https:\/\/42krunning.com\/wp-content\/uploads\/2026\/07\/camiseta-hombre-ignite-gray-42k-03-1-683x1024.jpg\" alt=\"\" width=\"683\" height=\"1024\"><\/a><figcaption id=\"caption-attachment-89639\" class=\"wp-caption-text\">IGNITE Grey<\/figcaption><\/figure>\n<p>This design provides a <strong>balanced technical fit<\/strong> and adapts very well to different types of athletes. The side vents favour mobility and help the T-shirt follow the body&#8217;s natural movement while running.<\/p>\n<p>Thanks to its combination of comfort, lightness and protection, IGNITE can be used both in everyday training and in races held in cool temperatures.<\/p>\n<h3>Technology applied to sporting performance<\/h3>\n<p>The IGNITE technical T-shirts incorporate different technologies to improve comfort, moisture management and the durability of the garment.<\/p>\n<h4>Soft-Light: softness to reduce chafing<\/h4>\n<p>The <strong>Soft-Light<\/strong> finish gives a soft, pleasant feel on the skin. This helps reduce friction and discomfort during long training sessions, especially in areas prone to chafing.<\/p>\n<h4>Dry-Tec+: breathability and quick drying<\/h4>\n<p><strong>Dry-Tec+<\/strong> technology helps wick away the moisture generated during exercise. The fabric moves sweat away from the skin, speeds up drying and helps regulate body temperature.<\/p>\n<p>This moisture management is especially important on cool days, when staying in a wet T-shirt can increase the feeling of cold.<\/p>\n<h4>DC4 \u2013 Long Life Run: longer-lasting colour<\/h4>\n<p>The <strong>DC4 \u2013 Long Life Run<\/strong> treatment offers high colour resistance to intensive sporting use and frequent washing.<\/p>\n<p>This way, the collection&#8217;s designs keep their intensity, definition and original appearance for longer.<\/p>\n<figure id=\"attachment_89640\" aria-describedby=\"caption-attachment-89640\" style=\"width: 683px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/42krunning.com\/wp-content\/uploads\/2026\/07\/camiseta-mujer-ignite-blue-42k-01-1-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-89640 size-large\" src=\"https:\/\/42krunning.com\/wp-content\/uploads\/2026\/07\/camiseta-mujer-ignite-blue-42k-01-1-683x1024.jpg\" alt=\"\" width=\"683\" height=\"1024\"><\/a><figcaption id=\"caption-attachment-89640\" class=\"wp-caption-text\">IGNITE Blue<\/figcaption><\/figure>\n<h3>Four designs to find your style<\/h3>\n<p>The <strong><a href=\"https:\/\/42krunning.com\/en\/collections-42k\/ignite\/\" target=\"_blank\" rel=\"noopener\">IGNITE collection<\/a> <\/strong>is made up of four models, each with its own graphic identity: Blue, Grey, White and Green.

This choice makes it possible to integrate recycled materials into a technical garment without compromising the performance that sport demands.<\/p>\n<p>The collection thus combines performance, durability and more responsible production, while keeping the features a running T-shirt needs: lightness, resistance, breathability and easy care.<\/p>\n<h3>When should you wear a long-sleeve technical T-shirt?<\/h3>\n<p>A long-sleeve technical T-shirt is especially useful during the autumn and spring months, as well as on winter days with moderate temperatures.<\/p>\n<p>It is also recommended for:<\/p>\n<ul data-spread=\"false\">\n<li>Early-morning training sessions.<\/li>\n<li>Runs at dusk.<\/li>\n<li>Windy areas or places with frequent temperature changes.<\/li>\n<li>Mountain races with changes in altitude.<\/li>\n<li>Sessions alternating periods of high and low intensity.<\/li>\n<\/ul>\n<p>The extra protection of the sleeves helps preserve thermal comfort, while the breathability of the fabric prevents excessive heat build-up.<\/p>\n<h3>IGNITE: keep running when it gets cooler<\/h3>\n<p>Cool temperatures do not have to become a limitation. The IGNITE collection brings together the features needed to maintain performance and comfort when a short-sleeve T-shirt is no longer enough.<\/p>\n<p>Its 140 g\/m\u00b2 Neo-Tec technical fabric, the 100 % recycled polyester, the unisex pattern with side vents and the Soft-Light, Dry-Tec+ and DC4 \u2013 Long Life Run technologies form a combination designed for athletes who want protection without losing lightness.<\/p>\n<p>Four designs, one philosophy: <strong>keep adding kilometres with comfort, protection and performance<\/strong>.<\/p>\n<p>Discover <a href=\"https:\/\/42krunning.com\/en\/shop\/mens-running-clothing\/mens-long-sleeve-t-shirts\/long-sleeve-running-t-shirt-ignite-blue\/\" target=\"_blank\" rel=\"noopener\"><strong>IGNITE Blue<\/strong><\/a>, <a href=\"https:\/\/42krunning.com\/en\/shop\/mens-running-clothing\/mens-long-sleeve-t-shirts\/long-sleeve-running-t-shirt-ignite-grey\/\" target=\"_blank\" rel=\"noopener\"><strong>IGNITE Grey<\/strong><\/a>, <a href=\"https:\/\/42krunning.com\/en\/shop\/mens-running-clothing\/mens-long-sleeve-t-shirts\/long-sleeve-running-t-shirt-ignite-white\/\" target=\"_blank\" rel=\"noopener\"><strong>IGNITE White<\/strong><\/a> and <a href=\"https:\/\/42krunning.com\/en\/shop\/mens-running-clothing\/mens-long-sleeve-t-shirts\/long-sleeve-running-t-shirt-ignite-green\/\" target=\"_blank\" rel=\"noopener\"><strong>IGNITE Green<\/strong><\/a> and choose the long-sleeve technical T-shirt that best suits the way you run.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When temperatures start to drop, choosing the right kit is key to staying comfortable and performing well during training.
