4. The G-Form Pro X3 Knee Pads

G-Form Pro X3 Knee Pads Review
The G-Form Pro X3 Knee Pads stand out in the protective gear market for their unique approach to impact absorption. Utilizing their proprietary SmartFlex™ technology, these pads are soft and flexible during normal activity, allowing for comfortable movement and a low profile. However, upon impact, the molecules in the padding instantly harden, dissipating energy before returning to their flexible state.

Unlike traditional hard-shell pads, the Pro X3 molds closely to your body, providing a comfortable, secure fit that doesn’t restrict motion. They are designed to be worn comfortably under clothing for extended periods. While they offer substantial impact protection for direct hits, it’s important to note that they don’t provide the same level of abrasion resistance as hard-shell alternatives, which is a factor to consider depending on your specific activity and the types of falls you anticipate.
What We Like
- Incredible Flexibility & Comfort: The SmartFlex™ padding allows for unrestricted movement and comfortable wear for hours.
- Low Profile Design: They are sleek and can easily fit under most clothing without being bulky.
- Effective Impact Protection: The padding hardens instantly upon impact, absorbing significant energy from direct hits.
- Breathability: The design promotes airflow, helping to keep you cooler during strenuous activity.
- Secure Fit: The compression sleeve design and silicone grippers help the pads stay in place.
What We Don’t Like
- Higher Price Point: G-Form pads are generally more expensive than basic foam or hard-shell alternatives.
- Limited Abrasion Resistance: While great for impact, they don’t offer much protection against sliding on rough surfaces.
- Sizing Can Be Tricky: Some users report needing to try different sizes to get the perfect, non-slip fit.
- Durability for Repeated Severe Falls: While good, repeated high-intensity impacts might compromise the SmartFlex™ material over time compared to hard plastic.
5. The POC VPD Air Knee Pads

The POC VPD Air Knee Pads are designed for riders seeking a balance between protection and comfort, particularly for trail and light enduro riding. These pads utilize POC’s lightweight VPD (Visco-Elastic Polymer Dough) Air material, which is soft and pliable at rest but hardens upon impact. This makes them incredibly comfortable and flexible for pedaling, often feeling barely noticeable during long climbs or flat sections. They offer a minimalist, slip-on design that fits smoothly under riding pants or shorts.
While they don’t offer the heavy-duty protection needed for aggressive downhill riding or bike park laps, they provide ample impact absorption for unexpected spills and crashes on moderate trails. The focus here is on providing discreet, reliable protection that doesn’t hinder movement or cause overheating. If you prioritize comfort, breathability, and freedom of movement for your everyday trail rides, the VPD Air pads are an excellent choice, offering peace of mind without the bulk of traditional knee pads.
Overall, they excel as a lightweight, comfortable option for riders who spend significant time pedaling but still want protection against common trail hazards.
What We Like
- Exceptional Comfort: The flexible VPD Air material conforms to your knee and feels natural, making them comfortable for all-day rides.

- Protection Coverage: Focuses mainly on the knee cap, less side or upper/lower shin protection.
Buying guide
Material and Durability
The choice of materials significantly impacts both the performance and lifespan of the product. Common materials include various fabrics like nylon or polyester, mesh, and natural materials like leather. Each offers different properties. For example, leather is renowned for its excellent abrasion resistance and traditional durability, though it can be less breathable and heavier than synthetics. Modern synthetic fabrics often offer a balance of durability, lighter weight, and improved breathability, sometimes incorporating advanced weaving or coating technologies. Mesh panels are frequently used to enhance ventilation but may reduce the overall protective capability in those areas. The product’s construction, such as reinforced stitching and the quality of zippers or closures, also plays a crucial role in its durability. A well-constructed item using high-quality materials will withstand repeated use and environmental exposure better, representing a smarter long-term investment. Consider how the materials will hold up under the specific conditions and stresses of your intended activity. **Choose materials that offer longevity and performance suitable for the intended activity.** Durable materials mean the product will last longer, saving you money and hassle in the future, while appropriate performance characteristics ensure it functions effectively.
Fit and Comfort
A proper fit is paramount for both performance and safety. An ill-fitting product can be restrictive, uncomfortable, and even compromise its protective function. It can lead to distractions, reduce dexterity or range of motion, and cause discomforts like chafing, blisters, or pressure points during extended use. Look for products that offer an anatomical shape or allow for customization to fit your body contours. Comfort features such as soft linings, padded areas (e.g., around joints or high-impact zones), and flexible panels that allow natural movement are important. Adjustable elements like straps, laces, buckles, or hook-and-loop fasteners enable you to fine-tune the fit for security and comfort. If possible, try the product on and simulate movements relevant to your activity. Pay attention to how it feels during motion and while stationary. Read reviews regarding sizing accuracy and comfort experienced by other users. **A secure and comfortable fit is crucial for performance, safety, and prolonged wear.** It allows you to focus on your activity without discomfort and ensures the product stays in place to provide its intended protection.
Protection Level
The primary purpose of many gear items is protection, and the level required varies dramatically depending on the activity’s risks. Assess the potential hazards you face – are they impacts, abrasions, punctures, twists, or environmental exposures? Products offer protection through various means: impact absorption (padding, foam, specialized inserts), abrasion resistance (tough outer materials), structural support (rigid panels, stays, braces), and coverage of vulnerable areas. Check if the product meets any relevant safety standards or certifications specific to its category or your activity (e.g., CE certifications for protective gear in sports or occupational settings). Understand what specific areas the product is designed to protect and the type of protection offered. Over-speccing on protection might add unnecessary bulk, weight, or reduce flexibility or breathability, which could hinder performance. Conversely, under-speccing could leave you vulnerable. Find the right balance based on a realistic assessment of risk. **Assess the required level of protection based on the activity’s risks.** Ensure the product provides adequate defense against the specific hazards you are likely to encounter.
Breathability
Breathability is crucial for managing body temperature and moisture, especially during strenuous activities or in warm conditions. Products with poor breathability can trap heat and sweat, leading to overheating, discomfort, reduced performance, and potentially skin irritation or chafing. Materials with inherent breathable properties, such as certain synthetic weaves, mesh panels, or perforated leather, allow air to circulate and moisture vapor to escape. Design features like ventilation channels or strategically placed vents also contribute to airflow. While there can sometimes be a trade-off between maximum protection (which might require solid, less porous materials) and breathability, many modern products incorporate technologies to balance these factors effectively. Look for descriptions or features that highlight ventilation and moisture management. Good breathability keeps you cooler and drier, enhancing comfort and allowing you to sustain your effort longer. **Good breathability prevents overheating and discomfort during strenuous activities.** It is a key factor in maintaining comfort and performance during prolonged or intense use.
Ease of Use
Consider how simple and convenient the product is to use in practice. This includes how easy it is to put on and take off, the simplicity and security of any adjustment mechanisms (straps, buckles, laces), and how straightforward it is to clean and maintain. Gear that is difficult to don, adjust, or remove can be frustrating, particularly in situations where speed or dexterity is needed. Complicated cleaning procedures can deter regular maintenance, potentially reducing the product’s lifespan or hygiene. Think about how the product integrates with other gear you might use. Can you easily operate equipment while wearing it (e.g., touch screens with gloves)? Are adjustments intuitive and secure, staying put during activity? Does the material lend itself to simple wiping, washing, or air drying? Products designed with user convenience in mind save time and effort, making them more practical for regular use. **Opt for products that are simple and convenient to use and maintain.** This ensures you are more likely to use the product consistently and can keep it in good condition.
Price and Value
Price is always a consideration, but it’s important to distinguish between initial cost and overall value. The price of products can vary widely based on factors like brand reputation, materials used, complexity of design, and the level of protection or features offered. While it might be tempting to choose the cheapest option, it’s crucial to consider the product’s durability and how well it meets your needs. A low-cost item that wears out quickly or doesn’t provide adequate comfort or protection might end up costing you more in the long run through replacements or compromised safety. Conversely, the most expensive product isn’t always necessary if a less costly alternative provides sufficient performance and features for your specific activity. Evaluate the quality of materials, construction, features, and expected lifespan relative to the price. Read reviews to understand real-world performance and durability. Think of the product as an investment in your activity enjoyment, performance, and safety. **Evaluate the product’s features, durability, and performance against its cost.** Look for the best combination of quality, functionality, and price that fits within your budget and meets your specific requirements.
