The original, 100% waterproof, windproof and breathable Sealskinz ankle length sock is perfect for use in a wide variety of weather conditions.  Wet feet are super uncomfortable and can lead to all sorts of not-so-good things outdoors.  The breathability of the hydrophilic waterproof membrane releases perspiration steam and warm air from inside the sock, creating a high level of comfort even when performing strenuous activities.  Stay cool, dry, and comfortable in these socks in rain or mud, snow, through stream crossings and standing in leaky waders.
