I have to confess, when I first started populating my wall, slopers weren't my first choice. Jugs, jugs, jugs!!!. But after some time, I realized that climbing on a wall full of jugs got boring really quick. Slopers added that needed challenge. This set of slopers is awesome. They're very large and I regularly grab these with both hands and I have big hands. They all have varying degrees of "slope" so they can be rotated to adjust the difficulty. I have 3 of them on a vertical surface and 2 on about a 20 degree overhang. The texture is grippy but not so rough that it damages finger tips. They're approximately 6"-7" at the base and stand 2"-3" off the wall.
