Prevail Mid-Weight 14" OTC Alpaca Sock

Reinforced midweight comfort and over-the-calf coverage for tall boots, long shifts, hunting, hiking, and hard-wearing days outside.

$40~$13 / year based on 3 years of wear

Prevail 14" OTC is our reinforced midweight over-the-calf sock built for tall boots, long shifts, hunting, hiking, and demanding outdoor wear. Balanced cushion adds comfort without the bulk of a heavyweight sock, while reinforced heel and toe zones help it hold up through boot friction, rough terrain, and repeated use.
