Kinking is the everyday annoyance with cheaper prusik cord — it fights you when dressing a hitch and wears unevenly over time. Boa's torque-balanced 16-plait construction was engineered specifically to eliminate that, so the sling sits smoothly and dresses cleanly hitch after hitch, which matters more over a season of daily use than any single strength figure on a spec sheet. Certified Protection Explained CE EN 566 is the European standard for slings used in mountaineering and climbing, confirming the Boa Sling's strength and construction meet certified safety requirements for professional prusik and friction-hitch use.

All Boa Slings are factory CNC sewn into closed loops, providing consistent strength and CE-certified performance. Do the slings have serial numbers? Yes, each sling is individually serial numbered to support inspection records and regulatory compliance. Is there an eco-friendly option? Yes, Blue Ocean Boa versions use recycled yarn while maintaining the same core performance benefits.
