RefrigiWear Glove Disclaimer RefrigiWear Comfort Ratings for gloves are for guidance only. We calculate ratings based on outershell material, insulation thickness and material as well as glove construction. However, comfort ratings cannot be a guarantee since each individual has a unique metabolism, circulation system, activity level and use for our products. Please take these considerations into account, and if extra warmth or additional moisture management is needed, please consider using one of our glove liners for extra protection.
