Men's Expedition 1/4 Zip Top

The base layer that works everywhere.

Office heating that can't decide between arctic and sauna. Early morning starts before the sun does anything useful. Full days outside when temps swing 30 degrees. You need a base layer that can handle all of it without forcing you to change halfway through.

The Expedition 1/4-Zip is built with DUAL SURFACE™ Precision Blended Wool - a lofted construction where each side of the fabric does something different. Inner surface pulls moisture away from your skin. Outer surface traps warmth and regulates temperature. This gives you serious insulation that still breathes when you're moving or when the environment changes.

What makes it work:

• Expedition-weight warmth that doesn't overheat
• High-performance wicking keeps you dry through activity changes
• Lofted fabric traps heat without bulk or restriction
• 1/4 zip for instant ventilation control
• Soft enough to wear against skin all day
• Durable through constant use and washing

Wear it as your daily driver in cold offices. Under your shell for dawn patrol. Solo on shoulder-season days. As your insulation base for serious cold missions. It transitions between all of them because the fabric actively manages what your body is doing.
Expedition-weight versatility. One piece, countless uses.
