Auxiliary rope made of 100% polyamide. This material is highly resistant and durable while being lightweight and flexible, making it easier to knot and transport the rope. The sheath of this auxiliary rope is made using our endurance braiding technology, which involves grouping the strands one by one to create a smoother, more compact, and uniform surface, providing increased resistance to wear from abrasion and extending the lifespan of the auxiliary rope. Additionally, this braiding effectively blocks the penetration of dust and small dirt particles that contribute to greater wear on the rope. Versatile and highly resistant to abrasion and dirt, it is ideal for a wide range of outdoor activities. Technical specifications: diameter: 4 mm strength: 3.3 Kn weight g m: 9.3 G.
