A raging tempest can discourage the uninitiated from venturing onto the frozen slopes that many of us call home, and the Tempest Thermal Neck Tube provides excellent fleece insulation due to its Polartec® Microfleece lining. An excellent choice for those that often find themselves cold, the Polartec® Microfleece™ Lining provides excellent low-profile thermal warmth. Repreve® Recycled Fiber is used throughout, from the lining to the PFC-Free ECO-DWR outer shell, making this mask one of the most sustainable fleece-lined neck tubes available today.
