Really good gloves. Took a bit of a risk and ordered small even though having measured my hands medium might have been the way to go. However the gloves are roomy so perhaps they are designed to allow for inners. Not the thickest feeling gloves so no bulky or clumsey. In bitterly cold conditions a pair of inners might be required although I have had them out in cold days without having cold hands. As to their waterproofing ability I haven't been in the right (wrong!) conditions to assess that. But Peral Izumi tend to make good quality products and I expect this to be no different. Also because I ordered the small size the price was great.
