ALPINESTARS 2026 YOUTH FLUID PORTL PANTS RED
Alpinestars 2026 Youth Fluid Portl Pants Red Light Gray Dark Green give young riders a relaxed, sport-fit take on Alpinestars’ race-proven MX construction, sized specifically for kids working their way up in the sport.
The Youth Fluid line borrows key construction ideas from the Supertech, Techstar, and Racer lines and scales them down for riders roughly 5 to 15 years old, delivering the most relaxed fit of the whole 2026 MX lineup. A 600D polyfabric forms the main chassis, with the same material reinforced at the seat and knees for added abrasion resistance in the areas young riders wear out fastest. Extended stretch corduroy panels run through the crotch, knees, back yoke, and inside legs, giving real freedom of movement in the riding position, while a pre-curved leg design helps reduce fatigue and keeps the fit natural through an active stance. An ergonomic 3D pattern construction keeps everything close to the body without restricting movement, and synthetic leather reinforces the inner knee for grip against the bike along with real heat resistance. A ratchet closure system lets the waist be dialed in quickly for a secure, personalized fit, and an internal mesh lining plus zippered fly round out the practical build. Finished in red, light gray, and dark green, this colorway is designed to pair with the matching Youth Fluid Portl jersey for a coordinated look at the track.
