Technical Specs & Key Details
Shopping Guide & Treatment Levels Explained: Please use the dropdown menus above to select your preferred rope color and length, then choose your treatment profile based on your climbing environment:
- Dry-Core: Maxim’s standard protective treatment where only the internal core fibers are treated to prevent moisture and dirt from rotting the rope from the inside out. Perfect for standard outdoor cragging and dry conditions.
- 2x-DRY: Maxim’s premium protective treatment where both the inner core and the outer braided sheath are fully coated. This creates a 100% waterproof barrier that prevents water absorption and freezing during ice climbing and alpine storms.
