Klim Sidewinder Wool Long Sleeve Shirt

The KLIM Sidewinder Wool Long Sleeve Shirt is a midweight performance long-sleeve built around Merino wool, designed to provide breathable warmth, moisture management, and natural odor resistance — ideal as a layering piece or comfortable stand-alone shirt for cool weather and outdoor activities.

🧵 Materials & Construction

• Blend: Midweight Merino wool (about 17.5 micron), polyester, and nylon — combining the natural comfort and thermoregulation of wool with the moisture-wicking of polyester and the durability of nylon.

• Fabric weight: ~220 g/m² (6.5 oz/sq yd) textile, giving it more substance than lightweight base layers while staying breathable and comfortable.

• Dual-layered fabric enhances airflow and comfort.

👔 Design Features

• Henley-style opening — a classic neckline that’s easy to wear under jackets or casual on its own.

• Engineered stretch for a greater range of motion during activity.

• Flat seams and offset shoulders reduce bulk under layers and help minimize seam chafing over long periods of wear.

• Regular fit — comfortable, not overly tight, suitable for layering.

🌡️ Performance Benefits

• Thermoregulation: The Merino wool blend helps keep you warm when it’s cool and comfortable as activity increases.

• Odor resistance: Natural wool fibers resist odor buildup, so the shirt stays fresher longer during extended use.

• Moisture management: Polyester and wool combination helps wick sweat away from skin, aiding comfort on the trail, ride, or travel.
