The Ion2 is the largest diameter rope in the fusion range. It's unique design is manufactured by first twisting multiple colored fibers into a single sheath-strand and then braiding the sheath to create the speckled pattern. It's diameter is a great size for intermediate climbers looking to match a lightweight rope with performance while knowing that the diameter isn't TOO thin for a beginner belayer.

“The ION2... Is great!!! It could be the best rope Sterling has made so far. I have been climbing non-stop with it since you gave me and I let everyone use and it is still in great shape. It might be slightly less dynamic than the Nano, but it works great... Cheers.” -- Nicolas Favresse
