A waterproof membrane makes the SealSkinz Trekking Sock more protective than most hiking socks. You'll appreciate this kind of protection when there's a myriad of muddy puddles between you and your backpacking destination. SealSkinz lined this sock with merino wool for heavyweight thermal regulation, natural odor-resistance, and a long-lasting soft feel. The elasticized ankle and instep provide support and a secure fit.
