Black Diamond Spark Mitts vs Hestra Army Leather Gore-Tex Mitt

Not at all waterproof. Warm, comfortable, NOT waterproof. Take incredibly long time to dry, even on a forced air, heated boot dryer. If you use these, you will need a pair of spare mitts to use while this pair dries

These have endured about 6 days of snowboarding so far, and they’re amazing! I am one of those people whose world ends when my hands or feet get too cold. These have kept mine toasty from -1 windchill up to spring-like temps. I measured according to Hestra’s instruction for sizing before ordering and purchased the recommended size. My mitts are quite roomy and a size smaller may have been a better fit for wearing with no liner, but they aren’t so oversized that it makes any difference in function
