A unique liner sock from Bridgedale with Isolfil® thermal fibre knit against the skin which traps warm air, keeping feet warm and dry.  These liners work best when worn under other technical socks in cold mountain conditions.

• Lycra® for a great fit, preventing sock movement which can cause blisters
• Isolfil® knit against the skin for maximum heat retention
• Reinforced heel and toe for durability
• Flat toe seams
