Mesh should be waterproof. There's simply no getting around it, if you want consistency out of your pocket then weather can't be a factor. STX's Weather Weave construction features independent strands of nylon intertwined and treated with a weatherproof coating, this keeps the fibers dry, extends the life of the pocket, and keeps your pocket more consistent throughout its use. Oh, and did we mention this mesh is 50% lighter than their regular dry mesh?!
