DMM Prowire 2 Quickdraw. The Prowire is one of the lightest of our current batch of biners. With an quickdraw weight of 80g you can afford to carry a big wall rack and still crank. Setting off on a 40m sport climb or taking a double rack on a sea cliff horror the weight of your gear can make the difference. The Prowire quickdraw comes on 12mm dyneema in lengths between 10 and 30cm.
