The X HOSE® Pro™ is made of super strong Dac-5 fiber webbing, and it's reinforced with a high-grade, drag-resistant Dac-5 polyester outer layer that's specially woven to make it tougher and stronger than ever! Its solid brass fittings and superior strain-relief collar are crush-resistant and the hose never kinks, making your yard and garden work hassle-free! Its thick, specially formulated latex inner layer expands to produce more velocity and higher pressure, so it's even more powerful. It automatically expands and then shrinks back to its original size.
