The Classic Hike Zero Cushion Liner Crew goes back to our original construction but adds in recycled Nylon for strength and durability while reducing environmental impact. This liner has an elasticized arch brace so your foot will enjoy a secure fit, and it will give you a flat knit toe seam for additional comfort. When you're ready for your next hike, be sure to grab a pair of these responsibly sourced Merino wool socks to make the most of each mile on the trail.

• 59% Merino Wool, 8% Nylon, 30% Recycled Nylon, 2% Elastane, 1% Polyester *Specific percentage of recycled Nylon will vary as SMARTWOOL transitions to 100% recycled Nylon in future seasons.
