From quick day hikes to lightweight overnights, the Hike+ Light Crew Intersecting Arrows Socks are a go-to for thermal regulation, breathable comfort and moisture management. These half-cushioned socks blend soft merino wool with nylon for durability and a touch of LYCRAA(R) to retain their stretchy, contoured fit. The reinforced heel and toe areas add to the long-term durability, and our seamless toe closure wards off blisters on high-mileage days. We also added an anatomical design, sculpted cushioning, and strategic support and breathe zones to maximize comfort and fit. FABRIC: 56% Merino Wool, 41% Nylon, 3% LYCRAA(R) PRODUCT WEIGHT: Medium = 90 g / 3.17 oz
