Climbing slings are extremely important for climbers. Essential for threading rocks, spike and tree placements, as well as setting belays. They are extremely versitile in their use and can be invaluable in extending runners and decreasing the likelyhood of ropes jamming. The choice of Nylon climbing slings or Dyneema climbing slings will be the big question for most climbers:
A nylon climbing sling is cheaper, but heavier. It is also very hard wearing so will last longer and is less prone to wear. Dyneema is half the width yet still maintains the exact same breaking strengths. Dyneema climbing sling is lighter but more expensive. We reccommend a wide selection of different slings, including size and type to make the best of what the rock provides.
Slings come in a variety of sizes, with the most popular being 60cm, 120cm, and 240cm. 30cm slings make for good extendable quickdraws. 60cm sling are the standard short sling that climbers use for spike runners and long extensions. This is an 'over the shoulder' type sling. It is common to carry a couple of these at all times. 120cm sling are often used slung over spikes and around objects such as trees. A 120cm climbing sling will double up over the shoulder. A 240cm climbing sling is very common at the belay and for this reason, it is often a Nylon type instead of Dyneema due to the types of wear they are subjected to being sling over boulders.
It is important to note, slings are cheap, and should be retired at the immediate sign of wear, a climbing sling is so well used that honestly, you can never have enough!
