BACKPACA Alpaca Hiker Sock – Lightweight Micro Cushion Crew The BACKPACA Alpaca Hiker Sock is a lightweight, micro-cushion crew sock designed for all-day comfort during active outdoor use. Terry loop construction along the sole provides targeted cushioning and support, while a ribbed knit across the top of the foot and up the calf enhances breathability and moisture wicking. A dense knit structure combined with integrated arch and ankle support bands helps keep the sock securely in place throughout the day, reducing slipping, bunching, and friction on the trail. U.S.-grown alpaca fiber delivers natural temperature regulation in both dry and wet conditions and is naturally antimicrobial, bacteria resistant, and odor resistant. Designed for warmer climates and seasons when a lighter, less bulky sock is preferred, this sock offers dependable performance for long outdoor adventures.
