G Form Size Guide

G Form is the industry leader in innovative protective sportswear, engineered specifically for athletes who demand the highest level of impact protection without sacrificing mobility. Our sizing philosophy is rooted in precision; because our gear is designed to absorb energy and dissipate force, the fit must be exact. A properly fitted G Form product stays in place during high-intensity movement, ensuring that the protective padding remains over the vital impact zones. Whether you are preparing for mountain biking, motocross, or contact sports, our sizing guides are designed to help you find a fit that is snug enough for security but flexible enough for peak performance. We cater to a global community of athletes, providing comprehensive conversion data to ensure that whether you are shopping from the UK, US, or EU, your gear arrives with the perfect anatomical alignment.

How to Measure

To ensure your G Form protection performs optimally, please follow these detailed measurement instructions. Accurate measurements are the most critical step in preventing the need for returns and ensuring your safety during athletic activity.

  1. Prepare Your Tools: Use a flexible, non-stretchable measuring tape. Avoid using metal construction tapes or stiff ribbons, as they cannot accurately contour to the curves of the body.
  2. Maintain a Natural Posture: Stand in a relaxed, upright position. Do not puff out your chest, arch your back, or hold your breath, as this will result in an incorrectly sized garment.
  3. Chest Measurement: Wrap the tape around the fullest part of your chest. Ensure the tape is level all the way around your back and remains parallel to the floor.
  4. 'Biceps and Limb Measurement: For protective sleeves and braces, measure around the widest part of the limb. Ensure the tape is snug but not compressing the skin.
  5. Thigh Measurement: For leg protection, measure around the fullest part of your upper thigh. This is essential for ensuring that padding does not slip during movement.
  6. Waist Measurement: Locate your natural waistline, which is the narrowest part of your torso, typically situated just above the navel.
  7. Hips Measurement: Wrap the tape around the widest part of your hips and buttocks to ensure proper fit for lower-body protection.
  8. Consistency Check: Perform each measurement at least twice to ensure the numbers are consistent.

Product-Specific Guidance

When selecting G Form protective gear, it is vital to consider the specific sport and the type of impact you expect to encounter. For impact-resistant sleeves (such as elbow or knee pads), the fit must be compressive enough to prevent the padding from migrating during high-velocity movement. If the sleeve is too loose, the impact protection may not align with the bone or joint during a crash. For torso protection, such as chest or back protectors, ensure the circumference of your ribcage and chest is measured accurately to allow for full lung expansion while maintaining the structural integrity of the padding placement.

Sizing Tips

  • Measure in the Evening: For all athletic gear, especially footwear, take your measurements in the evening. Feet and limbs tend to swell slightly after a day of physical activity, and measuring then ensures you do not purchase gear that becomes too restrictive.
  • The Two-Finger Rule: When fitting compression-based protection like sleeves, you should be able to fit two fingers comfortably under the edge of the cuff. If you cannot, the item is likely too small and may restrict circulation.
  • Avoid Muscle Tension: Always take your measurements while in a relaxed, neutral state. Tensing your muscles during measurement can lead to an undersized purchase that will be uncomfortable during actual use.
  • Prioritise Padding Alignment: If you find yourself between two sizes, choose the size that ensures the padding sits directly over the anatomical impact zone of your body. Safety takes precedence over a loose fit.
  • Consider the Sport Intensity: For high-impact disciplines like motocross, a slightly more compressive fit is recommended to ensure the gear remains stable through heavy vibrations and sudden jolts.
  • Check Product Reviews: Always consult customer feedback regarding specific G Form models. Some items may have a more "athletic" or "slim" fit compared to our standard protective gear.
