A series of weather‑defying shells, born from Sweden’s unrelenting wet-weather
In Sweden, rain is part of everyday life. With roughly 300 days of precipitation each year, outdoor activity doesn’t stop when weather shifts – it continues. Families hike, bike, and ski year-round, regardless of rain or snow, because moving outside is an integral part of the culture.
“That relationship with the outdoors starts early,” says Sofia Gromark, VP Design & Creative at Peak Performance. “You grow up going outside with your family in all kinds of weather, so performance and comfort aren’t optional – they’re expected.”
This mindset shaped the Treeline series by Peak Performance, a collection created for the everyday adventurers who embrace the outdoors not despite the conditions, but because of them. With a relaxed, contemporary silhouette, Treeline is built for variable conditions rather than extreme terrain. Clean lines and a modern fit allow it to blend naturally into city environments, while technical construction ensures dependable protection when weather and plans shift.
To support different needs and preferences, the Treeline shell is offered in two constructions: HIPE® 2.5L and GORE-TEX 3L. This dual approach reflects Peak Performance’s belief that there is no single solution for how people experience weather, movement, and comfort.
That philosophy is rooted in the brand’s heritage.
Since 1986, Peak Performance has been built on technical outerwear, beginning its long-standing partnership with GORE-TEX just two years later. Alongside this legacy, the brand has continued to innovate with proprietary solutions like HIPE®, developed to deliver breathable, everyday weather protection.
The Treeline HIPE® 2.5L Shell Jacket offers lightweight, breathable protection in a relaxed fit, ideal for daily wear and light outdoor use. The Treeline GORE-TEX 3L Shell Jacket provides enhanced durability and protection, featuring 3-layer GORE-TEX fabric and added safety elements for more demanding conditions.
Together, the Treeline shell system blends heritage, innovation, and versatility – designed for life outdoors, wherever it begins.
