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.


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.

How do I clean my Platypus bottle?

Platypus bottles are dishwasher safe. When placing Platypus bottles in a dishwasher, make sure they are fully expanded for optimal cleaning. Note: not all bottles may fit in a dishwasher, especially sizes 2L and greater.

You can also hand wash our bottles using warm or hot soapy water. Using our Reservoir Cleaning Kit helps access tough to reach places.

For deeper cleaning:

  • a. Per liter volume of your bottle, add ¼ Cup of baking soda to ¾ Cup of water and shake for 30 seconds (e.g., for a 2L bottle use ½ Cup of baking soda with 1 ½ Cup water).
  • b. Add ¼ Cup lemon juice per liter, close and shake 10 seconds, and vent by loosening cap away from face.
  • c. Re-seal bottle and repeat shaking and venting three times. Expel as much air as possible, cap bottle, and soak for 20 minutes.
  • d. Dump solution and rinse bottle three times with hot water.

Caution: When adding lemon juice to baking soda, effervescence occurs and will cause pressure to build in a capped Platypus product.

How do I dry my Platypus bottle?
Platypus bottles can be dried by blowing a little air into them to inflate, then letting them stand upright and uncapped until the water evaporates.
Can I put beverages other than water in my Platypus bottle, reservoir, or storage product?
You can put a variety of beverages in your Platypus bottle, reservoir, or storage product. Just make sure you clean it thoroughly after each use to prevent bacteria from growing in it (including any hydration tubes or bite valves). Carbonated beverages are not recommended.
How do I disinfect my Platypus bottle?
To disinfect your Platypus bottle, fill it with a solution of unscented household bleach and water, using a concentration of 2-5 drops per liter of water. Close and swirl for 10 seconds. Leave filled overnight. Dump solution and rinse bottle three times with hot water, then air dry. For a more planet-friendly alternative, use a chlorine-free, hydrogen peroxide-based bleach alternative like Free and Clear™ available from Seventh Generation®.
Can I freeze my Platypus bottle?
Yes. Lay it half-full on its side in freezer with all air purged. Do not over-fill. Water expands as it freezes and this can burst your bottle
The zipper tracks on my water tank are hard to close. Can I make it easier?
Yes. Periodically adding a little Vaseline to the tracks will keep them supple and easy to close. Wipe away any excess Vaseline. In the field, a little lip balm or water can do the trick. When closing the zipper, make sure to firmly pinch along its full length to properly seal it.
How do I ensure my Water Tank’s Big Zip™ closure is properly sealed?
From one end of the Big Zip™ zippered closure to the other, firmly pinch together both sides of the zipper along its full length. You should feel positive tactile feedback as the zipper connects and seals. Once sealed, invert the Water Tank to test the seal—a properly sealed Water Tank will not open in this test.
