The Bircham Waterproof All Weather Ankle Length Sock shrugs off any weather
What Our Gearhead® Experts Are Saying:
"I wore the Bircham Waterproof All Weather Ankle Length Sock through a genuinely soggy trail run and my feet stayed completely dry the whole way. The merino wool interior kept things comfortable without ever feeling clammy, even as I worked up a sweat."
Wet trail conditions have a way of ending a run early once feet get soaked, and the Bircham Waterproof All Weather Ankle Length Sock is built to keep that from happening. An Aquasealz™ waterproof membrane blocks moisture from outside while still releasing internal vapor, so feet stay dry through stream crossings, muddy singletrack, or a sudden downpour.
A merino wool interior adds natural sweat-wicking comfort along with antimicrobial properties that fight odor over long days, while a durable polycolon and nylon outer with 4-way stretch keeps the fit locked in through hiking, biking, or trail running.
