The Ksyrium line is Mavic's warmest series of gear, so it stands to reason that the Ksyrium Pro Thermo+ Gloves are the warmest gloves that the company makes. Indeed, they not only resemble full-on ski gloves, but they also share many design features with them. They have a synthetic shell that's laminated to a waterproof, breathable membrane and treated with a water-repellent DWR coating. Mavic opts for the lightweight Primaloft Sport insulation because it's non-bulky and stays warm even when it gets wet.
The classic lobster-claw design keeps your fingers together for extra warmth, and a soft microfiber insert on the thumb provides added breathability and a surface for wiping glasses or skin. A tough Clarino palm adds durability without sacrificing bar feel, and touchscreen-compatible inserts at the fingertips let you snap a quick photo of the conditions to show your riding buddies who sit bad weather out. The long cuff seals up with a hook-and-loop tab to keep heat in and moisture out, and reflective highlights on the fingers help you stand out even when the weather is less than ideal.
