All weld lines are not created equal, but they look about the same. For an untrained eye it´s hard to compare the quality and strength of a TPU weld line.
There is no magic recipe to get our quality. It´s years of testing and tweaking mould designs, TPU-qualities and thicknesses and being without comprise when the price tag hits our development.
It´s expensive to buy quality gear, but it´s more expensive to buy stuff you have to cancel after a couple of years with little ruff use. Even more expensive if all your electronics get´s flooded due to bad craftmanship or comprised welding.
Our weld standard and bond strength is more than 2 times as strong as the industri standard. Our bags get dropped from helicopters, shot out of submarine tubes and dragged to the top of our highest mountains.
