Featuring strategically placed 3D-molded silicone armor and additional foam padding, they offer substantial protection without hindering movement. They are also lightweight, comfortable, and stay securely in place, minimizing chafing on long rides.
While they might not excel in any single category as much as specialized pads, the Airflex Pro offers a remarkable combination of features. Riders seeking a do-it-all knee pad that performs well across different riding styles will find the Leatt Airflex Pro an excellent choice.

Offering a step up in protection from minimalist pads without the bulk of downhill models, the Airflex Hybrid is perfect for casual riders and those who enjoy long trail rides. They are low-profile, comfortable, and allow for unrestricted pedaling, making them feel barely there on the bike.
However, riders frequently tackling very rough terrain or bike parks might find the protection level insufficient.

Analysis and Test Results
Years of testing across diverse terrains inform our analysis of each knee pad model. We carefully evaluate performance against our scoring metrics to guide you in finding the best option for your riding style and budget. Detailed test results for each metric are discussed below.
What’s the Best Value?
While price isn’t a primary factor in our product ratings, we recognize the importance of value. Higher price often correlates with enhanced quality and performance, as seen with the POC Joint VPD System pads, which offer exceptional comfort at a premium price. The Fox Racing Launch D3O stands out as a strong value, delivering excellent performance at a mid-range price point. The Leatt Airflex Pro is another excellent value, providing well-rounded performance at a competitive price.
Protection
Protection is paramount for mountain bike knee pads, especially for new riders or those pushing their limits on challenging terrain. While experienced riders may opt for lighter-duty models, protection remains a crucial factor, accounting for 30% of our overall score.
Our protection assessment involves extensive wear and detailed evaluation of armor quality, thickness, and placement, rather than simulated crash testing. We analyze the technical features and design of each pad’s protective elements.
The 7iDP Project Knee excels in protection, featuring a long, durable knit sleeve and thick, flexible main armor with a hard plastic outer patch for sliding protection. Secondary padding around the main armor enhances protection against off-center impacts. While prioritizing protection, these pads sacrifice some breathability and pedal-friendliness but offer superior knee safety.

The 100% Surpass is another highly protective option, featuring a hard-plastic armor plate with auxiliary padding and foam above the kneecap for handlebar impact protection. Plastic or rubber coatings on most armor parts enhance durability against rips and tears. The Troy Lee Designs Triad also offers top-tier protection but sacrifices pedal-friendliness.
100% Surpass knee pads with plastic and rubberized armor for enhanced durability and protection against tears
The 100% Surpass knee pads feature plastic or rubberized armor coatings for superior durability and tear resistance.
Despite slightly less protection than the 100% Surpass and 7IDP Project Knee, the Fox Racing Launch Pro D3O provides excellent downhill protection with a superior fit and comfort. D3O padding and a removable hardshell cap offer a great balance of impact absorption and durability. The Launch Pro D3O is our top pick for bike park and downhill riding due to its blend of protection and comfort.

The Troy Lee Designs Raid Knee Guard and Fox Racing Launch D3O offer the next level of protection, providing very impressive impact resistance in sleeker designs. Soft, impact-hardening padding and auxiliary padding around the main armor offer robust protection, suitable for bike parks and shuttle laps, though with slightly less coverage than the top-tier protectors. The IXS Carve Evo+ and Endura MT500 Hard Shell Knee Pads also provide comparable protection levels.

The Leatt Airflex Pro delivers impressive protection for its versatility, offering significant impact resistance in a well-rounded package. The POC Oseus VPD Knee is another solid choice for aggressive trail riding, offering robust protection, though with slightly more bulk than the Airflex Pro.
For riders seeking sleek, pedal-friendly pads with enhanced protection, the Leatt Airflex Hybrid offers more protection than ultra-light options while remaining low-profile. Minimalist pads like the Fox Racing Enduro Knee Sleeve prioritize pedal-friendliness and comfort over maximum protection, suitable for less aggressive riding.

Fit and Comfort
Comfort and fit are essential for knee pads, influencing how often and how long you’ll wear them. Even highly protective pads are ineffective if uncomfortable. Our comfort assessment involves extensive wear during rides, daily activities, and prolonged periods to identify any discomfort or fit issues.
Standout performers in fit and comfort include the Fox Racing Launch D3O and Launch D3O Pro, offering a dialed, plush, and articulated fit. The D3O padding feels exceptionally comfortable throughout the pedal stroke, with a precise and consistent fit free of pressure points. The POC Joint VPD System also excels in comfort, prioritizing a pillowy feel with all-fabric construction to minimize irritation.
The Leatt Airflex Hybrid offers an extremely precise fit, with comfortable materials and a well-executed design that eliminates pinch points. The Fox Racing Enduro Knee Sleeve is another exceptionally comfortable option, prioritizing comfort over maximum protection with its soft, simple armor and conforming sleeve.

Pedal Friendliness
Pedal-friendliness is crucial for riders who value efficiency on climbs and varied terrain. While maximum protection is essential for some, pedal-friendliness can be a priority for others. Our pedal-friendliness assessment involves extensive pedaling on climbs, sprints, and casual rides to evaluate each pad’s impact on pedaling motion and comfort over time.
Minimalist knee pads like the Fox Racing Enduro Knee Sleeve and Troy Lee Designs Speed Knee Sleeve score highest in pedal-friendliness, feeling almost unnoticeable while pedaling. The Leatt Airflex Hybrid provides a good balance of pedal-friendliness and enhanced protection, suitable for riders wanting more protection without sacrificing pedaling efficiency.
The POC Joint VPD System Knee offers reasonable pedal-friendliness with mid-duty protection, providing a balance for riders who pedal and descend.

Ventilation and Breathability
Ventilation is crucial for comfort, especially in warm climates or during intense riding. Hot, clammy knee pads can detract from the riding experience. Our ventilation assessment focuses on airflow and breathability in various riding conditions.
Lightweight, minimalist pads like the Troy Lee Designs Speed Knee Sleeve, Fox Racing Enduro Knee Sleeve, and Alpinestars Paragon Plus offer the best ventilation due to their minimal material and soft foam construction. Airflow is maximized through these pads, although they are still not entirely “cool.”

Durability
Durability is an important factor, ensuring your knee pads withstand crashes and repeated use. While durability accounts for 10% of our score, it impacts long-term value. Our durability assessment involves evaluating construction, materials, and design, based on extensive riding and crash experience, though not intentional crash testing.
The 100% Surpass stands out in durability, featuring plastic or rubber-armored padding for maximum resistance to rips and tears in crashes. The Fox Racing Launch D3O Pro enhances durability with a hardshell knee cap, protecting a high-impact area. The 7iDP Project Knee is built for durability with burly knit construction and a hard plastic armor plate, designed to withstand demanding riding conditions. The Endura MT500 Hard Shell Knee Pads and IXS Carve Evo+ are also rugged, featuring thick materials and robust construction.
