ALPINESTARS 2026 YOUTH FLUID PORTL PANTS UCLA BLUE
Rounding out the Youth Fluid Portl range with a cool, clean finish, Alpinestars 2026 Youth Fluid Portl Pants Ucla Blue White pair a comfortable sport fit with race-inspired construction sized for young riders.
The Youth Fluid line takes key construction ideas from the Supertech, Techstar, and Racer lines and adapts them for riders roughly 5 to 15 years old, offering the most relaxed, forgiving fit in the entire 2026 MX lineup. A 600D polyfabric main chassis is reinforced with the same material at the seat and knees, adding durability exactly where young riders need it most. Extended stretch corduroy panels through the crotch, knees, back yoke, and inside legs allow real freedom of movement, and a pre-curved leg design helps reduce fatigue during an active riding stance. The ergonomic 3D pattern construction keeps the pant close-fitting without restricting mobility, while synthetic leather reinforces the inner knee for both grip against the bike and heat resistance. A ratchet closure system lets the waist be adjusted quickly for a secure, personalized fit, and an internal mesh lining along with a zippered fly complete the practical build. Finished in UCLA blue and white, this colorway is designed to pair with the matching Youth Fluid Portl jersey for a coordinated look on race day.
