HAND:
Measure around the fullest part of your palm, keeping the tape measure horizontal.
If you’re on the border between sizes then the choice is up to you, for a closer and more athletic cut then go for the smaller size or if you’d like a bit more room then size up. These gloves work best when they're tighter to improve the thermal properties.
The length is given as a measurement from the base of the palm to the tip of the index finger.
The measurements given are designed as a simple guide and should not be used for exact measurements, nor do they provide an assurance of sizes.
