Giving back to those giving their all: COVID-19 update

Joining Forces to Support Our Communities

Our Cascade Designs family of brands is truly inspired by the heroic efforts put forth by our communities during this crisis—from the medical responders to the grocery store employees. Resolved to help, we’ve joined forces and refocused our manufacturing muscle to assist with making protective gear. Like so many, we wish to give back to those giving their all.


100,000 Level 1 Surgical Masks

Our Seattle production team quickly shifted gears to sew medical masks in response to the shortage of PPE for health care professionals. On April 30, we met our goal of 100,000 masks! The materials were provided by Kaas Tailored and the masks have been going to 51 Providence Hospitals, as part of their 100 million mask challenge.


Safety Gowns for Firefighters

Firefighters protect our lives; we’re humbled to help protect theirs. Working with King County Emergency Management, we’re using Therm-a-Rest mattress materials to help make protective gowns for local firefighters. The durable material is easily disinfected after each call, making the gowns reusable. It also withstands the harsh environments firefighters face far better than disposable gowns.


Special Discount for Healthcare Workers

To express our immense thanks to the medical professionals working tirelessly to fight COVID-19, we're offering healthcare workers a special discount across all of our brands for the next year. If this includes you, please sign up here. And thank you for all you do!


PackTowl® Cloth Face Masks

Still need to join the mask movement? Grab a PackTowl washable, reusable face mask. Our team began sewing them for our employees, and now we've made them available to everyone. For every $5 mask sold, we're donating $1 to the CDP COVID-19 Response Fund supporting vulnerable populations impacted by the pandemic.

Pick up your face mask here!


As a family of brands, we know how critical it is to help one another. We’re grateful to be part of an incredible community of adventurers—regardless of which uniform you wear to work. From all of us at Therm-a-Rest, MSR, SealLine, Platypus and PackTowl, let's keep doing our part, so we can see each other on the trails once again.

What is the difference between "splashproof," "waterproof," and "submersible"?

SealLine products use three ratings to describe water resistance:

  • Splashproof: Withstands light rain and splashes. Only some of our products fall into this category. Suitable for use where light water resistance is sufficient, such as summer backpacking.
  • Waterproof: Withstands quick submersions and will float if dropped in the water. Most of our bags fall into this category and are suitable for canoe, kayak and rafting use where boats may tip, flip or be swamped.
  • Submersible: Withstands 1 meter of submersion for 30 minutes (IP-67 standard). Suitable for use in extreme and prolonged wet situations.

With such ratings, water resistance depends on the user carefully and properly sealing the closure. For roll-top closures, this means a minimum of three tight, wrinkle-free rolls. For zipper closures, the zipper must be completely and properly closed.

What does the IPX7 rating on E-Case® cases mean?

IP codes are part of the International Electronics Commission’s system for classifying the degree of protection provided by enclosures of electrical equipment. The consumer electronics industry has adopted this standard for classifying protection of consumer products.

E-Case® cases are rated IPX7. This means, when properly sealed, they’ll protect your valuables in one meter of water for up to 30 minutes. We individually test every case to ensure that each one meets this rating.

Which size E-Case® should I get for my smartphone (or electronic device)?

We recommend finding your nearest SealLine dealer and checking in person which size E-Case your device best fits within. We know it’s not always possible to check sizing in person, so we’ve provided each case’s internal dimensions (compartment length and width) on the E-Case product page. In general, if the measurements of the device are at least 3 cm shorter than both the length and width of the internal dimensions of a particular E-case size, the device should fit within that size case as long as the device is not thicker than 10 mm.
