Cascade Designs, the marketer of brands like Therm-a-Rest, MSR and Sealline, is launching an additional brand named E-Case. The label is dedicated to waterproof protection cases for smartphones, tablet computers and other fragile devices. The Seattle-based company wants to meet the growing demand for waterproof protective equipment to keep high-tech equipment dry. Previously, Cascade already offered some items for water sports marketed under the label Sealline, but the outdoor company considers this business as strong enough to serve it with a specialty brand. E-Case stands for gear which allows to protect and to additionally use portable computers under wet and sandy conditions, including the handling of touch screens and audio functions. The products, which will hit the shops under the new label by spring 2013, will be manufactured in Cascade's own plants in Seattle and Cork, Ireland.
