Woodstock Tip-Up Line is one of the toughest, stealthiest specialty lines around. Its unique round configuration and tightly braided nylon make it exceptionally strong and manageable. During its manufacture, Woodstock Tip-Up Line line is subjected to a 3-step heat-set and waterproofing process to reduce stretch and resist freeze-up once it hits the ice. You won't find a tip-up line that performs better, is more durable, or has more hook-setting power! Tough, yet stealthy Super-tight nylon braid Strong, manageable, low stretch Waterproofed to resist freeze-up
