Omega Pacific wanted a carabiner that had all the benefits of a wire gate design light, simple, reliable, and strong . . . But, they wanted a shape that could pull some all-mountain duty like rigging biner brake raps, alpine clutches . . . something you could aid on without that scary shifting as you load your aiders.Trouble is, no such carabiner existed - anywhere. So, they built the Doval and introduced an entirely new category of carabiner At 37gm, its a featherweight shave pounds off your rack by trading up and the Ovalized-D frame means you can stack them and reverse the gates just like on ovals and regular Ds. With 25mm of gate clearance, its a perfect clipping carabiner. Its wide rope-bearing surface is a true radius, which means there arent any flat spots in the interior to wreck your ropes. Finally, an all-mountain wire gate. Versatile, Functional, and Affordable.
