UL waterproof mittens from RaidLight, a French trail running brand. Brand new, unused. I think it's a rare item. These are over-mittens like those from Yamato Michi, Yamatabi, and OMM. Unlike those, these have seam sealing for waterproofing. Originally designed to meet specific race regulations, these are ultra-lightweight waterproof/breathable over-mittens. They are perfect for all outdoor activities, can be carried in an emergency, and used instantly. In mountain activities, they provide warmth for your hands in case of sudden changes in weather, such as rain or cold temperatures. Over-mittens are less bulky and incredibly light, making them much more versatile for runners as a waterproof layer for their hands. Furthermore, you can wear inner gloves for insulation and warmth depending on the conditions. Whether it's a windy day or a sudden thunderstorm, over-mittens will protect your hands, making them the perfect ultra-lightweight mittens for running in the rain. - Weight: 10g/one hand - Water resistance: ResponsivMP +® membrane on the palm: 15K.
