Description

Reengineered from the inside out, the new Vortex Half Zip marks the evolution of a TAD essential—now purpose-built as a true expedition base layer capable of thriving across shifting climates, high-output movement, and deep-cold environments. At its core is Polartec® Power Grid™, an advanced bi-component knit engineered to increase warmth, reduce mass, and accelerate moisture transport. This specific weight of Power Grid is exceptionally versatile—warm enough for cold-weather missions yet breathable enough for high exertion—making it the ideal next-to-skin foundation when operating across varied terrain. We reshaped the silhouette into a more form-fitting, body-mapped profile that sits comfortably under shells and midlayers without bunching or bulk. The result: smoother transitions, more efficient heat management, and a base layer that moves with you, not against you.  A higher-profile collar delivers superior neck and head insulation, sealing out drafts and optimizing warmth retention during exposed conditions.  A deeper half-zip length delivers powerful thermal regulation - dump heat fast during high-output climbs or seal in warmth when the winds turn hostile. Dual angled chest pockets are placed for easy access even under shells - perfect for keeping a phone or battery-sensitive gear close to your core when temperatures threaten performance. Integrated into a gusseted construction, the thumbholes lay flat and comfortable when not in use and provide secure wrist anchoring when layering. From alpine traverses to backcountry cold snaps, the Vortex Half Zip is the thermal engine that keeps you ready for whatever the expedition demands. Gear up with the new Vortex. 'Built for those who demand capability.
