Our 4 Season Gloves, Frontier Mittens, and Children's Mittens all have our waterproof membrane in their construction. As a reminder, the leather will show water absorption on the exterior of the glove/mitten, the waterproof membrane protects your hand on the interior of the glove from external moisture.
For a more detailed look at the design / layers of the gloves and mittens, please check out this video. Design is from the beginning until around 0:48.
If you're thinking, "This is true, but I think the waterproof membrane is faulty in my pair..."
Understood! Please reach out to us with pictures of your gloves/mittens and where the moisture is coming in. This will help our team understand how to move forward with a solution.
