Perfect for long, multipitch routes, the CAMP Mach Express Dyneema Double Length Quickdraw has it all. A superlight 8 mm Dyneema sling connects the incredibly light Nano 23 carabiner to the superlight, full size Photon Wire. The Nano 23 is great for slings and chains, and the Photon Wire makes for easy clipping. 10 mm x 60 cm Dyneema runner. Thin Dyneema slings are a great choice for alpine draws. Not only are they light, but they do not absorb water. They wont get soggy in wet conditions or freeze up.
