The Alpinestars AT 8 Merino Underwear Pants are a performance-focused base layer designed for motorcycle riding, outdoor activities, and everyday wear. This black XL/2XL model uses a 250-gram blend of 55% Merino wool and 45% polyester to provide warmth, thermal regulation, breathability, and comfortable moisture management. The 100% Merino wool inner layer offers a soft next-to-skin feel, while the 100% polyester exterior supports fast drying when layered beneath riding gear.
Designed for extended use, the AT 8 base layer helps manage moisture and resist odor during multi-day trips and demanding rides. Full seamless construction reduces bulk and irritation beneath motorcycle pants, while the integrated crotch gusset supports unrestricted movement in the riding position. The ankle-length design provides dependable coverage beneath riding apparel without interfering with boots or other protective equipment.
A 4 cm elastic waistband with signature Alpinestars branding helps provide a secure, comfortable fit, and the functional fly opening adds practical convenience. The sustainable, versatile construction makes these underwear pants suitable as a motorcycle base layer or for casual daily wear. The Alpinestars AT 8 Merino Underwear Pants are supplied in black in size XL/2XL and are identified by manufacturer and vendor part number 4750227-10-X2X.
