Therm-a-Rest® ProLite™ Plus 06089

UPDATED FOR 2015- ALL-SEASON SELF-INFLATING COMFORT- NOW WITH EVEN LESS WEIGHT AND BULK

The ProLite Plus mattress combines outstanding all-season warmth with the convenience of self-inflation. An upgrade to our exclusive Atmos™ Foam reduces weight and boosts compressibility. In addition, patent-pending diagonal-cut foam delivers more warmth than the more common vertical channels, making it the ideal choice for ski touring, cold weather expeditions and winter camping. Stuff sack included.

• Lighter: Atmos™ Foam reduces weight by nearly 10%.
• Four-Season Warmth: Thick, patent-pending diagonal-cut foam offers efficient year-round comfort.
• Ultra-Compact: Atmos Foam boosts compressibility for easy packing.
• Self-Inflating: Expanding foam core self-inflates; top off with just a few breaths for personalized firmness.

Atmos™ Foam

Our exclusive Atmos™ foam provides outstanding loft while also maximizing compressibility and minimizing weight. The secret is in the manufacturing process. Foam is typically produced in open containers where chemicals and "foaming" agents are mixed. This causes a reaction in which air bubbles get captured in the material as it changes from a liquid into a foam. 

Atmos™ foam goes through this same process but in an atmospherically-controlled chamber, in nearly weightless conditions, netting two key benefits. First, this allows the foam to rise unhindered by the weight of the liquid itself, resulting in a much higher and uniform distribution of air cells, absent of dense areas that can add weight and compromise performance. Second, 100% of the gases resulting from the reaction can be captured and filtered before it is released back into the atmosphere, making this the cleanest foaming process in the world. More comfort for you, less harm to the environment for everyone, and it's manufactured in the USA. We think that's pretty great.
