100% 40040-00000 Hydromatic Waterproof Mountain Bike Short Black Size 28

The 100% Hydromatic Short is a waterproof mountain bike short designed to keep riders dry and comfortable during wet-weather trail rides. Featuring a lightweight, aerodynamic fit, this short combines weather protection with athletic performance for serious mountain bikers who refuse to let rain stop their ride.

Advanced Waterproof Construction:

• 2.5-layer mechanical stretch woven fabric with 10K/10K waterproof and breathable laminate
• Fully sealed seams prevent moisture penetration at critical points
• Water-resistant coating minimizes liquid penetration on the surface
• Cordura back saddle panel provides enhanced abrasion resistance for durability

Key Features:

• Boa System dial and lace technology for lightweight, incrementally adjustable waist closure
• Silicone print on inside waistband keeps shorts securely in place during aggressive riding
• Waterproof zippered pockets on thighs keep essentials dry and secure
• Hidden snap closure above fly for a clean, seamless appearance
• Reflective logos enhance visibility in low-light conditions
• Slim, athletic cut reduces flapping and improves aerodynamics

The Hydromatic Short is designed to fit over your favorite chamois or padded liner without adding bulk. The polyester-elastane stretch fabric promotes excellent range of motion while the breathable laminate helps manage perspiration during intense climbs and technical descents. Perfect for early season rides, unexpected rain showers, or consistently wet trail conditions.
