Solution-dyed fabric uses pre-dyed fibers to minimize the water and energy required to color the fabric. This means that color, or pigment, is added to the material producing the completed fabric. Compared to conventional batch-dyeing—the process of dyeing already produced fabric— solution dyeing requires significantly less water and energy, reducing waste and carbon emissions.

Check the floor dimensions of your tent to see if they will accommodate the extra width of a NeoLoft pad. Lengthwise, every NeoLoft size will fit in the typical backpacking tent.

The floor dimensions of most 2-person backpacking tents are typically 50-52 in (127-132 cm) wide by 88-90 in (223-229 cm) long. If your 2-person backpacking tent is 52 in (132 cm) wide, then it will fit two Regular Wides or two Longs, or one of each. If your 2-person backpacking tent is 50 in (127 cm) wide, two of the wider NeoLofts will bulge slightly against the sides, but it will easily fit one Regular Wide or Long and one Regular.

A Regular Wide NeoLoft measures 26 in x 73 in (66 cm x 185 cm), whereas a Regular XLite™ NXT measures 25 in x 72 in (64 cm x 183 cm). The NeoLoft’s 3D construction utilizes a sidewall band that attaches the top and bottom fabric. The sidewalls bulge out a bit when inflated, adding a touch of extra length and width.
No it’s not; we borrowed the ‘Neo’ moniker due to similarities in the internal constructions of the NeoLoft and the NeoAir pads. The NeoAir uses Triangular Core Matrix construction and the NeoLoft has ContourCore Matrix construction.
Optimized for industry-leading warmth-to-weight ratios, Triangular Core Matrix is used inside our lightest, most compact sleeping pads. ContourCore Matrix uses the same thermally efficient design (two stacked layers of triangular chambers that disrupt convective heat loss) but incorporates a more flexible urethane material that allows for a thicker pad and superior contouring support. It’s heavier and less compact but maximizes comfort.
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.
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.
Self-inflating sleeping pads rely on the compressible and rebound-able open cell foam cores to self-inflate. The atmospheric pressure around the pad pushes air into the rebounding open cells when the valve is opened. Check out our blog post for more information.
Generally, it takes 5-15 minutes for any of our self-inflating pads to inflate on their own. That 10-minute variance range is probably due to one of the following factors: core construction, trained compression, elevation and temperature. We find the most significant factor is trained compression (i.e. if your pad is new and has been factory rolled on the shelf for some time or stored rolled up for a few months). Check out our blog post to find out why.
Self-inflation begins when the valve is opened and ends when equilibrium is reached between the atmospheric pressure outside the cells and the air pressure within the cells pushing the other way. In our experience, most users’ comfort level requires more air than the equilibrium level, which is why self-inflating pads don’t inflate “all the way.” Check out our blog post for more information.
  • 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.

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.

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.
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.
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.
  • Yes. Classic Valve Replacement Kits can be purchased here.
  • WingLock™ Valve Replacement Kits can be purchased here
  • If you’re having issues with your TwinLock™ Valve, our warranty & repair team is here to help. Please visit thermarest.com/warranty for more info.
  • If you’re not sure which valve you have please refer to the graphic below:
  • Valve Type
  • 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.
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
  • 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
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.
  • 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.
