XL ski knee pads are designed for a knee circumference of approximately 44-48 cm, measured around the center of your kneecap with your leg slightly bent. This size is typically meant for very large adults or anyone with broader knees and thighs who finds a large size too snug.
Getting the right size is critical for protection. A pad that's too loose can slide out of position during a fall—exactly when you need it most. An XL pad that fits properly will stay anchored over your kneecap instead of migrating down your leg.
To find your size, wrap a soft measuring tape around your knee at the kneecap center with your leg slightly bent. If you're between L and XL, size up if you prefer comfort or want room for base layers underneath, or go with L for a more secure, locked-in feel. Always check the brand's specific size chart, since measurements vary between manufacturers.
