Mizuno and Woolmark have come together to unveil its newest base-layer and leggings made from Mizuno’s Breath Thermo performance technology, now combined with Merino wool. Breath Thermo was first developed 30 years ago as a moisture-absorbing and heat-retaining base-layer for winter sports apparel, previously made entirely from synthetic fibres. Since working with Woolmark, Mizuno has elevated the technology with the addition of Merino wool.
Trusted by Ski Team Sweden Alpine, the base-layer and leggings are engineered for extreme conditions and designed for comfort and unrestricted movement for optimum athletic output. Merino wool’s natural performance benefits ensure the garments are temperature regulating, odour resistant and lightweight, offering functionality ideal for athletes training and competing in cold weather.
Lightweight and high-performing, both the base-layer and leggings carry Woolmark’s Wool Blend certification, signifying wool fibre quality and performance, tested against rigorous standards.
- The base-layer is crafted from a fabric blend, uniting Breath Thermo with Merino wool, to generate heat from body moisture while providing Merino wool’s natural insulation, moisture control and odour resistance. Soft and lightweight with excellent stretch, it offers warmth and freedom of movement without weight or bulk.
- The leggings share this innovative fabric blend, keeping muscles warm through heat generation while Merino wool adds breathable insulation, odour resistance and comfort.
Both garments are trusted by Ski Team Sweden Alpine and will be worn as they team compete at the 2026 Winter Olympics.
“Merino wool has always been trusted by elite athletes, and Ski Team Sweden Alpine’s reliance on it says it all. Partnering with Mizuno unites natural performance with cutting-edge innovation, proving how Merino wool continues to lead in next-to-skin layers made to perform under pressure,” says Woolmark Managing Director, John Roberts.
“As a global Sports Performance Brand, Mizuno is proud to not only support the best global athletes with the highest quality products, but also by adding tremendous technological value through collaborations like this one with Woolmark. With the dedicated Merino Wool Breath Thermo base-layers, Mizuno aims to support the Ski Team Sweden Alpine with market-leading products for years to come,” says Mark Kaiway, Mizuno EMEA Head of Sports.
“Mizuno strives to deliver the highest quality. This is reflected both in our collaboration and in their product development such as the Merino Wool Breath Thermo base layer. The drive to perform connects us, which is why I’m very happy to partner with Mizuno,” says Fabian Ax Swartz professional alpine ski racer for Ski Team Sweden.
But you don’t have to be an elite athlete to wear the best performance wear. The Mizuno base-layer and leggings will be available to shop on 12 November 2025 via Mizuno.com.
