Meet the brand new Coastrek crew sock, a bold trail essential in our signature purple colourway. Made with ioMerino’s premium merino wool blend, you can expect the superior endurance and comfy softness merino is loved for, as well as natural temperature regulation, breathability and odour resistance to keep you happy on your feeet all day. Overall the socks are 63% merino with 35% polyamide and 2% elastane but the foot of the sock is closer to 80% merino with more poly up top. With extra crew-length coverage for cooler mornings and more rugged trails (and sandy stretches!), these trail socks not only look great but are perfect for training hikes, your Coastrek Event Day and keeping any creepy crawlies at bay!
