Main Story. 06. 24.
High in the Dolomites, where stone faces stretch endlessly into the clouds, La Sportiva was started with the mission to bring climbers, runners, and mountain lovers closer to the land they adore. The brand has been forged by generations of bootmakers and mountaineers who never forgot that performance at altitude isn’t about fashion; it’s about trust. Trust in your footing, your layering, and your limits. Which is why Polartec is providing the La Sportiva design team with best-in-class textile technologies ranging from Polartec® Delta™ cooling fabric to the lightweight warmth of Polartec® Power Grid™. Because alongside the innovation that comes from the company’s deep connection to the mountains, are the textiles that keep you warmer, dryer and more comfortable – so that you can go farther.
“We chose Polartec® Delta™ and Polartec® Power Grid™ for their advanced technical performance, their ability to enhance overall comfort, and their proven effectiveness during high-intensity physical activities. These fabrics offer exceptional breathability, moisture management to keep the body dry, and long-lasting durability and comfort, thanks to their engineered resistance to wear and tear. These features are essential for the technical performance of garments designed for intense outdoor activities.”
Giulia Colnaghi – R&D Apparel development Manager.
La Sportiva began as a small mountain workshop in a remote mountain valley, but its impact has extended far beyond its alpine roots. Over the past 90 years, the company, together with the community in which it was founded, has redefined how the world explores altitude. From its first handmade boots in 1928 to crafting gear fit for iconic ascents, La Sportiva represents the climbers, mountaineers, runners, and craftspeople who have helped shape both the gear and the experience of moving through vertical landscapes. It’s a story interwoven with the milestones of modern alpinism and the everyday efforts of those who choose the mountains as their path. Still today, the company’s steadfast commitment to innovation, performance, and respect for the environment brings purpose and precision to every product it produces.
When it comes to high-output pursuits and steep vertical climbs, La Sportiva’s answer to managing heat and sweat without slowing down comes in the form of Polartec® Delta™, a premium evaporative cooling fabric that actively assists the body’s natural thermoregulation process. Featured in the Ridge T-Shirt, Traverse Tank and Beyond Longsleeve shirt, Polartec® Delta™ disperses sweat, boosts airflow, and prevents wet cling, making it perfect for endurance runners, high-altitude hikers, and climbers navigating sun-drenched ridgelines. This same attention to detail is found in the Aequilibrium Thermal Hoody, designed in collaboration with alpine guides to deliver breathable warmth without the weight. Crafted with Polartec® Power Grid™ technical fleece, whose patented grid construction enhances compressibility while reducing overall fabric mass, making it easy to layer, quick to dry, and built for movement.
Like La Sportiva, Polartec has spent decades pushing the limits of technical textiles, and their collaboration is built around solving real-world mountaineering problems. Polartec® Delta™ keeps your skin cooler, even under sun-exposed climbs. Polartec® Power Grid ™ traps heat without adding weight. Add in Polartec® Fresh Face, an odor control treatment made from mint, not metals, and you have gear that works hard without compromising sustainability. After all, when your brand is built in the mountains, protecting them is essential.
