Mega in size, soft comfort and warmth, MegaMat is the ultimate sleeping mat for campers and overlanders who want a premium, reliable, best-in-class sleep experience. With 4 inches of cored foam, MegaMat provides a soft sleep surface ideal for side sleepers. Dial in your exact firmness further by using the included Top-Up Pump to add more air or by opening the valve to purge excess air. What does a "soft" comfort experience mean? MegaMat provides soft, pressure-relieving support that cradles the body. It is the “Goldilocks” comfort experience of the camping mat line and is an ideal choice for both back and side sleepers.

• 4" mattress height: 4" mattress height comprised of high-quality open-cell polyurethane foam keeps sleeper warm & comfortable, providing ample thickness to keep most campers from "bottoming out"
  
• Air-core-channeled foam insulation: Air channels cored out of the foam allow your mat to take in air during self-inflation and purge air again for convenient storage & transport and reduced weight
  
• Welded side handle: A practical welded side handle makes for easier handling and carrying ability; no more awkward mat grappling
  
• Soft, recycled material: No one wants a rough or scratchy mattress; the soft, 100% recycled 4-way stretch tricot polyester surface material cradles the body & provides next-to-skin comfort
  
• 3D construction: 3D vertical sidewall construction maximizes available sleep area & reduces tapering at the edges, similar to your own mattress at home

PRO TIP: It may sound counterintuitive, but if you find that your camping mat is just a little too hard, use the inflate valve to purge excess air. By opening the valve and pressing gently on the one-way flapper, you can release controlled bursts of air to reach the exact firmness you want. If you open the extra-large deflate valve, you may find yourself losing more air than you anticipated and need to top off your mat again.
