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.

Providing comfort and value for those discovering a love for the outdoors, the Trail Scout uses premium self-inflating foam for essential comfort at camp. The 1-inch (2.5 cm) thick pad gives users three-season comfort with a 3.1 R-value. The pad compacts small enough to easily fit into your pack when it’s time to hit the trail. The versatile self-inflating pad features the high-performance WingLock valve, which has three times the airflow rate of the classic valve thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the Trail Scout is made in market to ensure quality and minimize environmental impact. The pad includes a compact stuff sack.

How do you inflate and deflate sleeping pads with a WingLock™ Valve?
  • Watch this video for step by step instructions on how to use the WingLock™ Valve
  • To Inflate the WingLock™ Valve:
    • Unroll your sleeping pad and open the valve cap by twisting it counter-clockwise.
    • Use a pump sack or breath to inflate your pad. The one-way valve will prevent air from escaping.
    • Continue inflation until the mattress is fully inflated and close the valve by twisting the valve cap clockwise.
  • To Deflate WingLock™ Valve:
    • Open the wings to open the one-way valve.
    • Open the valve cap by twisting counter-clockwise, allowing air to escape
    • Roll the pad toward the valve end, pushing any remaining air from the pad.
Can I replace my old Therm-a-Rest valve with a new WingLock™ Valve or TwinLock™ Valve?
No. WingLock™ or TwinLock™ Valves cannot be installed on products that originally included a Classic Therm-a-Rest Valve. If you’re not sure which valve you have please refer to the graphic below: Valve Type
What makes the WingLock™ Valve different from Classic Therm-a-Rest Valves?
  • Faster Inflation: Larger valve opening and one-way inflation allows three times faster airflow than our classic valve (with a pressurized air supply the Classic Valve flow rate measures to 2.2 standard cubic feet per minute, where the WingLock Valve flow rate measures to 6.5 standard cubic feet per minute, or a 295% difference).
  • One-Way Inflation: Unique design keeps air from escaping during inflation.
  • Deflation “Wings”: When it’s time to break camp, open the valve and twist the wings to deflate your pad twice as fast as our classic valve.
  • Watch this video to learn more
What makes the TwinLock™ Valve different from Classic Therm-a-rest Valves?
For our larger pads, we developed the TwinLock™ Valve which utilizes two one-way valves: a one-way inflation valve and one-way deflation valve that allows for five times faster deflation than our classic valve. Watch this video to learn more.
How do you inflate and deflate sleeping pads with a TwinLock™ Valve?
  • Watch this video for step by step instructions on how to use the TwinLock™ Valve
  • To Inflate TwinLock™ Valve:
    • Unroll your sleeping pad and open the “IN” valve by twisting it counter-clockwise.
    • Use a pump sack or breath to inflate your pad. The one-way “IN” valve will prevent air from escaping.
    • When the mattress is fully inflated and close the valve by twisting the valve cap clockwise.
  • To Deflate TwinLock™ Valve
    • Open the “OUT” valve by twisting counter-clockwise.
    • The one-way “OUT” valve will keep air from flowing back into the pad.
    • Roll the pad toward the valve end, pushing any remaining air from the pad.
How should I store my sleeping pad?
  • Self-Inflating: We recommend storing the mattress unrolled and fully inflated in a dry place with the valve open. This will ensure the foam self-inflates faster when camping. Storage for a prolonged time in a damp space may cause mildew damage which is not covered by our Limited Lifetime Warranty.
  • NeoAir: We recommend leaving the valve open and storing your mattress rolled tight in a stuff sack to protect it from dirt and sharp objects.
What is the best way to clean my sleeping pad?

Regular cleaning will extend the life of your mattress, especially if you sleep in direct contact with its surface.

Do not put your mattress in the washing machine. Cleaning with a hose or in a bathtub is best. Do not forget to close the valve while washing. For general cleaning, a quick scrubbing with Formula 409®, BioClean All-Purpose Cleaner, or other general household cleaner is best.

For tree sap, spot clean with a cotton rag soaked in rubbing alcohol. This will take some work and sap will likely leave a stain. However, a dusting with talc or baby powder when you are done should eliminate any residual stickiness.

How warm is my sleeping pad and what is the ASTM testing standard?
ASTM F3340-18 is a new testing standard that provides R-value ratings for sleeping pads. While Therm-a-Rest has always used R-value to rate our sleeping pads, this new standardization will allow campers to make “like-for-like” comparisons with our competitors pad. Head to a blog for an in-depth explanation.
What should I do if I think my sleeping pad is losing air?
If you think that your NeoAir or self-inflating sleeping pad are losing air, it’s possible that you have a puncture in your pad. If you want to repair your pad at home, check out this blog post. If you’d like to send your pad to our Seattle repair shop, head over to our warranty page.
How should I inflate my self-inflating pad the first time?
For best performance, inflate your self-inflating pad with air by breath or pump and sack and leave the mattress fully inflated for 2-4 hours before your first use.
How do I inflate my self-inflating pad during winter?
In freezing conditions, avoid breath inflating your self-inflating pad. The moisture from your breath can freeze inside the mattress. The mattress may self-inflate slower in cold weather. Use a pump sack or electric pump if the pad needs additional air.
What is the benefit of stretch knit fabric on my sleeping pad?
For comfort-conscious campers, we use stretch knit fabric for unrivaled support and superior next-to-skin feel. The fabric conforms to your body to provide supple support as you enjoy your nights under the stars.
