These are extremely lightweight and very warm down mittens from Rab at an incredible value.  Designed for high altitude use, polar expeditions, and for emergency use on alpine climbs and extreme cold weather winter adventures of all sorts.  The wide opening cuff makes these mittens extremely easy to get off and on.  Synthetic Stratus™ insulation is incorporated on the sidewall, palm, and inside thumb for added moisture resistance in damp conditions.
