How to Choose the Correct Glove Fit

Choosing the correct glove fit is essential to your safety and comfort.

• The glove must be loose enough to shake off your hand in one motion, in the event of saturation with cryogenic fluid
• Too tight a fit leads to thermal loss
• Tempshield’s gloves are sized appropriately to take quick removal into account - order your true size
• If your length and width sizes do not match, order your width size - the cuff will cover any additional length needed 

Sizing Guide

• For your hand length, measure from the fold of your wrist to the tip of your middle finger.
• For your hand width, make a fist with your dominant hand and measure the circumference below your knuckles. Do not include your thumb.
