Note: XLC overshoes are in European sizes.
If you’ve found a nice pair of gloves but don´t know your glove size, you can measure one of the gloves you own and use the result to find your glove size in the sizing chart below.
You can also measure the circumference of your hand, as illustrated.
Make sure you always measure your dominant hand, and if you’re between sizes, it’s advisable to choose the larger of the two sizes.

Use a measuring tape to measure the circumference of your hand as illustrated, by wrapping the tape measure around your palm below the knuckles.
Always measure your dominant hand. If you’re inbetween sizes, it’s best to pick the larger size!
Measure the circumference of your head to determine your helmet size (as illustrated).
If you’re between sizes, choose a XLC cycling helmet in the larger size to make sure your helmet fits.
Most XLC bicycle helmets and XLC children’s bicycle helmets are equipped with a turning mechanism, so you can tighten the helmet to fit you.
