Cypher Sling

Dyneema is significantly lighter and thinner than nylon, making it ideal for alpine climbing or long multi-pitch routes where weight and rack bulk are critical. It also absorbs less water, which prevents the sling from freezing stiff in cold, wet conditions.

Yes, these slings are CE EN566 certified and feature a breaking strength of 22 kN, which meets the standard safety requirements for climbing anchors and protection extension.

The 8mm diameter is quite slim, which is great for packing, but it can be slightly harder to grip than wider nylon webbing. Most climbers find them perfectly manageable for alpine draws and anchor building, though they may feel different if you are accustomed to thicker, wider slings.

While they are strong enough to hold the forces generated in top-roping, Dyneema has a very low melting point and poor heat resistance compared to nylon. If you are setting up a top-rope anchor that will see significant movement or friction, nylon is generally the safer, more durable choice.

Keep them away from sharp edges and excessive UV exposure, which can degrade the material over time. Inspect the stitching and webbing before every use for signs of abrasion, fuzzing, or discoloration, and retire the sling immediately if you notice any significant wear.
