RockTape's "Big Daddy" is a first in the kinesiology taping industry - a supersized roll that is 4" wide and 105' long. If you prefer to cut your own applications from rolls of kinesiology tape, you'll love this "widebody" roll that allows for complete customization for every situation.Big Daddy is perfect for larger areas like the thigh and lower back, allowing custom applications without cutting multiple strips. ROCKTAPE is a premium kinesiology tape that features a tighter weave, greater elasticity and stronger adhesive than other kinesiology tapes. A tighter weave means enhanced support for working muscles and joints. Extra elasticity promotes "snap back," helping muscles contract and relax more efficiently. And Rock Tape's stronger adhesive allows it to stay on longer, even under the toughest conditions. This makes it an ideal athletic tape for high performance athletes and those competing in extreme sports.
