Feather uses a close S–XL fit and generally fits smaller than many standard North American winter gloves. Measure the circumference and length of both hands and use the larger measurements when selecting a size.
If your circumference and hand length indicate different sizes, or you are near the upper end of a size range, use the larger size as your starting point.
Feather can be worn beneath a roomy outer glove, but its 2.3mm construction is thicker than a dedicated 0.5mm liner. The outer glove must leave enough room for Feather, your fingers and the wrist battery area without restricting movement.
Use the Arcfomor glove size guide and calculator before ordering.
