Mountain Laurel Designs produce some very interesting gear. These are Rain Mitts, to go over our merino gloves.
These Rain Mitts weigh in at a miserly 34 grams for the Large and 31 for the Medium.
They are constructed from eVent fabric, which we very much enjoy, and are minimalistic without compromising functionality.
One thing that is truly super-neat, is the one handed wrist pull.
The mitts are not seam sealed, but come with a tube of Seam Grip +WP that you use to complete the seams. I've just done mine after watching the video on the Mountain Laurel Designs website: fiddly, but not difficult.
We're yet to use them on a hike yet… will update when we do.
