The Alpinestars AT Merino Bottom are designed for adventure riders and outdoor use in cold, demanding conditions. Built with a dual-face 250g construction, these base layer pants combine a Merino wool lining for natural climate control and next-to-skin comfort with a durable polyester exterior for shape retention, durability, and pill-resistant performance. The advanced fabric blend provides excellent thermal regulation, moisture-wicking performance, and natural odor resistance, making them ideal for long rides and multi-day wear. Full seamless construction with an integrated crotch gusset enhances mobility and eliminates pressure points for greater comfort in the riding position. A 4cm elastic waistband with Alpinestars branding ensures a secure fit, while the functional fly opening and ankle-length design add practicality for everyday layering. Whether under riding gear or worn as part of a cold-weather system, the Alpinestars AT Merino Bottom delivers dependable warmth and comfort.
