Welded seams (Radio Frequency (RF) Welding)
Using high frequencies, two tissue parts are connected to each other at the molecular level. This robust and reliable as well as waterproof method is much better and more durable than sewn and glued seams. An RF seam is up to twice as strong as conventional seams that are only sewn and glued over. This results in an uncompromisingly protective and longer lasting seam.
