    Warm, 4-way stretch fabric
    Reinforced, flat seam construction
    Form fit, ideal under a helmet


    The ideal layering hat. The Heatweave™ thermodynamic fabric keeps your noggin warm. The formfitting construction allows for a perfect fit under a helmet.

    Seirus’ exclusive Heatwave™ lining provides the first dual-stage heating system, both
    reflecting and amplifying heat. The kinetic stage converts emitted energy into increased heat, while the reflective stage reflects radiated heat back for more warmth. The versatility of this material allows it to be used in everything from gloves to socks. Look for the silver lining and increase your heat.
