The Liner + Hiker is a perfect sock set for every hiking adventure - from a quick day hike to a multi-day backpacking adventure. The Liner is an ultra-thin base layer designed to wick away sweat from your foot - keeping it dry and comfortable. Since the toes are separated, skin on skin friction is eliminated, helping to prevent blisters. The Hiker is worn over the Liner for increased cushion and protection. The Hiker mirrors the shape of your toes, providing more room and reducing bunching.
