Alpinestars AT Merino Wool Baselayer Top Black

• High-grade natural Merino wool construction delivers active thermal regulation across varying ambient temperatures.
• Advanced moisture management pulls sweat away from skin to prevent dampness and chilling during long rides.
• Natural antimicrobial and anti-odor properties help maintain freshness on multi-day touring expeditions.
• Low-profile ergonomic flat-lock stitching eliminates chafing and pressure points beneath motorcycle riding jackets.
• Streamlined collar and tailored cuffs prevent bunching and seal out cold highway wind drafts.

Ride through cold mornings and unpredictable weather transitions with this high-performance technical base layer. Engineered for powersports touring, off-road adventures, and street commuting, this long-sleeve thermal top utilizes premium natural Merino wool fibers to provide exceptional warmth-to-weight performance without unnecessary bulk.

The natural fibers dynamically regulate body temperature by trapping insulating air pockets when it is cold and allowing excess body heat to vent as intensity increases. Moisture-wicking performance draws perspiration away from the skin, keeping you dry and preventing dangerous wind-chill during long highway stints. Ergonomic patterning and low-profile flat-lock seams ensure smooth mobility and prevent hot spots under armored leather or textile riding gear.
