Merino Convict Canyon Half Zip

The Convict Canyon Half Zip targets hikers, ski tourers, and climbers seeking an active midlayer that can handle sweat without smelling terrible after two days. Built with a merino wool and synthetic blend, it addresses the traditional shortcomings of both materials. Pure merino often sags and stays damp when worked hard, while pure synthetic fleeces harbor stink and lack natural thermoregulation. Blending the two yields a balanced fabric with internal lofting that traps warmth when stationary yet breathes freely on the move.

On trail, the piece behaves much like a technical grid fleece with superior odor control. The deep half-zip front works effectively to vent core heat on sustained climbs, saving you from having to strip down completely in freezing air. Because the face fabric is porous to maximize moisture transfer, biting winds cut right through it; you will need a shell or windshirt ready the moment you stop or reach an exposed ridge. Durability is decent for a merino blend, though high-abrasion areas can pill over time if continually rubbed by heavy pack straps or rough harness gear.

It packs down compactly into an overnight kit and fits smoothly under both minimalist wind shells and hefty down parkas without bunching. Compared to synthetic staples like the Patagonia R1, it trades a fraction of pure tear resistance and drying speed for significantly better multi-day odor management and a softer hand feel. For cold-weather users who dislike the synthetic clamminess of standard grid fleeces, this layer strikes a practical, hard-to-beat middle ground.
