Cascade Designs is focused on the outdoor industry. Launched by two former Boeing engineers, avid backpackers, they created the world's first self-inflating camping mattress. They called their invention Therm-a-Rest®, and their fledgling company Cascade Designs. Therm-a-Rest quickly became standard equipment for adventures worldwide. But for Cascade Designs it was just the beginning. During the past three decades, the company has grown into a family of brands, offering a wide variety of outdoor products and expanding into new markets. These brands include SealLine®, maker of portable storage products; Platypus®, specializing in flexible bottles and hydration systems; Tracks®, manufacturer of walking staffs and trekking poles; MSR®, a pioneer in innovative backcountry gear; and Varilite, specializing in wheelchair positioning products.
