Size Small ski gloves and mittens are designed for a hand circumference of 6.5 to 7.5 inches, measured around the widest part of your palm (excluding the thumb). This size fits most women and smaller men, but measuring is the only way to know for sure — don't just guess based on your usual clothing size.
Getting the right fit matters more than you might think. If your gloves are too tight, they restrict blood flow to your fingers, which actually makes your hands colder even with premium insulation. Too loose, and you lose that critical layer of trapped air that keeps you warm. A properly fitting Small should feel snug but not squeezed, with a small gap at the fingertips.
One common mistake: if you plan to wear a liner glove underneath, measure and try on your gloves with that liner in place. Sizing can also vary between brands, so always check the specific size chart rather than assuming consistency.
