Kitsbow Releases New & Updated Polartec® Alpha® Collection

Alpha Jacket & Vest Leverage High-Performance Fabric to Materialize Active Insulation.

PETALUMA, Calif. (Nov. 1, 2018) After officially announcing a long-term partnership with Polartec earlier this year, Kitsbow is excited to announce that the new Alpha Vest and updated Alpha Jacket made with Polartec® Alpha®––the active insulation technology that regulates core body temperatures throughout the widest range of conditions and activity levels––are now available for purchase.

Originally developed for the U.S. Special Forces as first breathable insulation technology, Polartec® Alpha® eliminates the need of shedding or adding layers during both dynamic and static activities.

“Collaborating with Polartec on these styles was a no-brainer,” said Zander Nosler, Founder and CEO of Kitsbow. “The Alpha technology does a superior job at balancing airflow, insulation, and moisture transport, which is exactly what riders need to stay comfortable and warm, whether they’re on a grueling bikepacking trip or commuting to work and hitting up happy hour after. There’s nothing else like it.”  

We love the attention to both technical detail and style that Kitsbow provides to riders,” said Gary Smith, CEO of Polartec. “As a cyclist myself, I’m delighted to see their continued embrace of our Polartec Alpha insulation technology which enables the greatest comfort and design flexibility in insulated garments.”

Kitsbow has updated its existing Alpha Snap Jacket and added a new performance-oriented Alpha Vest to the line, both engineered with Polartec® Alpha® 80g hydrophobic insulation on the front of the torso and a lighter Polartec® Alpha® 60-g insulation on the back (and in the sleeves of the jacket). This combination of insulation, lining and DWR shell are designed to work in unison to manage breathability and body temperature, keeping you dry and comfortable in all conditions.

The new Alpha Jacket has also been refined and improved with new colors and is a fresh continuation of its previous distinctive style. MSRP: $350

Leveraging the successful style and features of the Alpha Jacket, the new Alpha Vest is the faster and lighter sibling, serving as an insulative layer that you can wear on its own or under a wind shell, with as little bulk as possible. MSRP: $250
