Knee/Elbow Pads, Gloves and Apparel
TSG uses different measuring points depending on protector. Bike gloves and clothing use model-specific sizing on product pages. No unrelated hand/body measurements are transferred without a clear current brand master chart.
Safety notice: Torso length is particularly important for back protectors. A protector that is too long or short can shift protective zones. Follow the TSG instructions for the specific product.
