The TUO Kinetic Merino 250 1/4 Zip Shirt is a cold-weather base layer engineered for outdoor enthusiasts who demand warmth, comfort, and reliable performance in every expedition. Crafted from premium merino wool, it delivers a soft touch, excellent moisture management, and versatile layering for chilly days in the field.

• Fabric weight and construction: Warm 250g interlock fabric provides balanced insulation and structure for base-layer wear.
• Material: Premium 18.5-micron merino wool offers a soft, itch-free feel against the skin.
• Moisture management: Naturally moisture-wicking and antimicrobial to keep you dry and fresh during high-output activities.
• Thermal regulation and breathability: Advanced thermal regulation balances warmth with ongoing breathability as your activity level changes.
• Seam construction: Flatlock seams reduce chafing and deliver comfort under a pack or mid-layers.
• Ventilation and layering: Quarter-zip design lets you dial in temperature and makes layering easy when moving between environments.

The result is a versatile base layer that stays warm when the temperature drops, yet breathes when you're charging uphill. The merino's natural odor resistance helps you feel fresh on multi-day trips, while the flatlock seams and snug fit prevent rubbing during long wear. Pair it under a shell on icy mornings, or use it as a standalone warm layer during shoulder-season excursions—the TUO Kinetic Merino 250 1/4 Zip Shirt adapts with you.
