Multiflex and Tigerflex are both made in the USA with identical flexibility and appearance. The difference is that Multiflex has a full EPDM rubber layer on the inside, creating a smooth surface. Visually, if you look inside a Multiflex hose you will see all black, whereas when you examine the inside of a Tigerflex hose you will see the plastic helix. Because of this EPDM rubber layer on the inside of the Multiflex hose, they are slightly heavier but tend to last longer than their Tigerflex counterpart. Lastly, Multiflex is only available in black and green while Tigerflex has a range of available colors.
