We invented the first c-sling 8 years ago, every year we make new versions with different fit and more features. We wanted our Hunkyjunk c-sling to fit the Huj style ideals: CLUTCH is pure hunkyjunk. It has thicker walls for more support, the super soft material grips all the way around: more andldquo;push it up and outandrdquo;andmdash;most importantly a bigger bulge! CLUTCH is more cushion everywhereandmdash;it surrounds in rubbery thick supportandmdash;the best feature is thicker rubber around the base of the shaft that plumps up the shaftandmdash;it has a andldquo;donutandrdquo; of silicone blend around the ballsack that feels really good. CLUTCH just feels really good, put it on and be Huj! Our plus+silicone TPR/silicone blend: silicone for a smooth and warm feel, TPR for amazing stretch and strength. Phthalate free. Dimensions: Width: 2 in. Height: 2.75 in. Depth: 2.25 in. Main Hole Circumference: 4.25 in. Shaft Hole Circumference: 3.75 in. Ball Hole Circumference: 3.5 in.
