Multifunctional Thermonet® Neckwear

After years of tailored R&D, our newest collaboration with BUFF® introduces Bifrost, a multifunctional neckwear piece engineered for substantial warmth with minimal bulk.

Named for the Old Norse bridge between worlds, Bifrost is built for cold, exposed transitions where protection must adapt as conditions shift. Featuring Thermonet® technology, crafted from PrimaLoft® insulating fibres, this technical innovation redefines breathable warmth in a luxuriously soft fabric made from 58% recycled materials.

Lightweight Thermonet® technology is 4x warmer than a regular microfibre helping to keep you warm even in extreme cold. Its fast-drying and sweat-wicking properties help prevent the fabric from freezing and keep your body temperature steady.

A seamless 4-way stretch knit provides optimum freedom of movement and is extremely soft against the skin for all-day comfort however you wear it.

Bifrost is the perfect technical addition for any high-output mountain sports, as well as being adaptable for everyday wear. Bridging conditions when the weather turns and exposure is unavoidable.

"There is a dwelling, by name Himinbjorg, which stands at the end of heaven, where the Bifrost−bridge is united with heaven" - Excerpt from The Prose Edda (13th century, Old Norse ancient literature).
