VBL Socks S grey

VBL Socks from Exped are insulated socks for extremely cold conditions - for example when climbing mountains or hiking in winter. The socks are vapor impermeable and are worn over thin or under thick socks. This prevents the shoe insulation from becoming damp with sweat and helps keep the feet warmer. The seam at the heel and toe is designed to reduce chafing and blisters.
