Herren Merino-Mischung 125 ZoneKnit™ Langarm-Crewe-Thermoshirt

The ZoneKnit panels make such a difference on steep climbs—I stayed surprisingly dry while my buddies were soaked in their old thermal tops. It's light enough to forget you're wearing it, but it's done the job on every chilly morning run so far.

The ZoneKnit panels make a real difference when the pace picks up — I stayed dry on a trail run that would've left me soaked in my old cotton long sleeve. Also surprised how much stretch it has for being so light.

I’ve been reaching for this top on long trail runs because the Cool-Lite fabric keeps me from overheating, yet I don’t feel chilled once I stop moving. The fit is snug without being restrictive, and the lightweight feel is perfect for layering under a shell.
