The GT Ultraz Winter Booties are constructed with our dual-layer twinDeck textile construction for maximum insulation and weather protection in the harshest winter conditions.

• Featured Fabrics ThermoShell is the primary textile used, applied in two overlapping layers. This 3-layer softshell features a PU-bonded membrane plus a perforated circular knit face - increasing breathability without sacrificing thermal protection. There's also a DWR treatment on the outer layer for one extra level of protection
• Construction/Fit In addition to our dual-layer twinDeck construction, the booties feature a reverse camlock zipper, while our zeroCuff creates the smoothest transition possible between your legs and the fabric, furthering the aerodynamic profile
