Because when you’re facing brutal conditions, failure is not an option. This philosophy has earned the trust of elite military units, mountain rescue teams, professional athletes and outdoor enthusiasts alike. It’s also the reason why **Jöttnar relies on Polartec® innovative fabric technologies** to deliver best-in-class gear that is also extremely lightweight and packable. “*Using Polartec® Alpha™ active insulation and its air-exchange technology gives us the ability to build temperature-stabilizing midlayers, such as our Asger lightweight hybrid fleece jacket and hoody, that span a wider effective operating range. To have this within a single garment ultimately means less on-off layering, more comfort, less faff, more speed.*” – cit. Tommy Kelly, Co-Founder of Jöttnar. ![3 Polartec FP JOTTNAR 768x768](https://polartec-polartec.transforms.svdcdn.com/production/img/3-Polartec-FP-JOTTNAR-768x768.jpg?w=450&h=450&auto=compress%2Cformat&fit=crop&dm=1739544013&s=88836fb903b26e9b4a04eb34bf9bff67) ![6 Polartec FP JOTTNAR 768x768]() ![5 Polartec FP JOTTNAR 768x768]() ![4 Polartec FP JOTTNAR 768x768]() ![2 Polartec FP JOTTNAR 768x768]() ![1 Polartec FP JOTTNAR 768x768]() **An Evolution of Excellence** With its roots forged in extreme environments, it’s no surprise that Jöttnar and Polartec share a unique perspective on **reliability**, **durability**, and the demands on clothing subjected to brutal conditions. Like the military background of the brand’s co-founders, [**Polartec® Alpha™** ](https://www.polartec.com/fabrics/insulation/alpha)was developed for the US Special Forces **to effortlessly handle the stop-go conditions** of active combat. Featuring an **active air-exchange system for temperature variations** and stop-start conditions, this **next-to-skin insulation** excels when actively put to work. By adapting to your internal body temperature, [Polartec® Alpha™](https://www.polartec.com/fabrics/insulation/alpha) delivers **consistent warmth and breathability**, releasing excess body heat during adrenaline-fueled activities before saturation and discomfort occur. **Breaking the Mold** Debuting six years ago and returning after its 2023 sell-out with near-perfect reviews, **Jöttnar’s new Asger HS jacket** is now more refined than ever. **Designed for high-output activities**, this technically sophisticated jacket pairs a **windproof**, **water-repellent outer fabric** with [**Polartec® Alpha™**](https://www.polartec.com/fabrics/insulation/alpha) fleece for **unmatched comfort and functionality**. Asger HS is a **versatile**, season-proof jacket that seamlessly transitions between **outerwear** and a **midlayer**, depending on the weather and your needs. Its athletic fit and articulated arms are enhanced by stretch cuffs, harness-compatible pockets, and a handy chest pocket to store your essentials. What’s more, the **unique breathability of Polartec® Alpha™** fleece insulation reduces the need for constant layering adjustments, **making the Asger HS a game-changing essential for adventurers on the move**. **Tested by the Best** Not that anyone needs proof that the Asger hybrid fleece jackets and hoodies are worthy of the hype, but you should know that **all Jöttnar products are battle-tested by Pro Team athletes** and used by specialists **including elite ski patrol and mountain rescue teams**. Just **ask BASE jumper and alpinist Tim Howell**, who says his Asger HS combines “insane breathability with incredible warmth,” making it a non-negotiable cornerstone in his kit. And because **Asger is expressly designed to handle mid-to-high-intensity alpine activities**, this three-season staple delivers unrestrained freedom, comfort and performance without the added bulk. **Not just better – Unstoppable** Forged to tame the UK’s most rugged peaks, Jöttnar is pushing the performance envelope with gear that inspires confidence and exceeds expectations. Its collaboration with Polartec is built on a **shared commitment to innovation and excellence**, letting Jöttnar stand firm in its mission to **enable adventurers to go beyond limits**. So if you’re like us and refuse to compromise on performance or design, you probably call this partnership a perfect match.
