11mm dyneema slings. 11mm is pretty much the new standard diameter for slings nowadays as they offer a good compromise between weight and durability.
60cm: Big enough to go over your shoulder without being doubled, a handy length for spike runners and extending out of the way protection.
120cm: Fits over most shoulders doubled up. Ideal for most uses from setting up belays, extending runners and using as an abseil sling.
240: A big sling made for setting up belays. Ideal for top roping and group work, etc.
