Ample rounded jug pockets. One is a deep two full finger pads which could be used in a roof in the intermediate V3 range. The other pocket is slightly shorter at one and a half pads deep.
It can be grabbed using thumb catches right where the two pockets meet. Grabbing it that way will almost feel like it is a ring. Your fingers will end up about 3/4 inch from touching each other.
Consider this jug to ease up any terrain that is less than roof.
