Instead of having all of the leg straps permanently sewn to save a few grams, which can result in a nightmare on launch if you are trying to get into it with crampons or boots on, we have chosen light weight aluminum plate buckles with colour coordinated leg straps for easy and safe identification. The padding on the back and inside the legs makes the Oxygen1 the lightweight harness that you can fly comfortably for hours. After all, if the wing is soarable, the harness should be as well!
