A backpacking-focused reimagination of Exped’s plush camping mat, the MegaMat Ultra ($250) prioritizes comfort and ease of use over low weight and a compact size. With its thick, mattress-like build, soft tricot surface, and vertical sidewalls, it delivers some of the best sleep you can get in the backcountry. It’s too heavy and bulky for long routes, but for short overnights, basecamps, or car camping crossover use, it’ll help you dream easy.

Exped MegaMat Ultra
For this season's top models, see our guide to the Best Backpacking Sleeping Pads.
At 4 inches thick, the Exped MegaMat Ultra is one of the most comfortable backpacking-capable sleeping pads I’ve ever used. The only pad that surpasses it in thickness is the Therm-a-Rest NeoLoft at a head-turning 4.6 inches, but the Ultra holds its own even against that super-luxe model thanks to its plush feel, rectangular shape, and vertical sidewalls. When I slept on it, I snoozed as deeply as I would at home—it’s that comfortable.
The baffles run vertically rather than horizontally, giving the pad a uniform, mattress-like feel while helping prevent pressure points. Combined with the raised sidewalls, the design lets you use the full sleeping surface—there’s no annoying taper or sense that you’re about to roll off the edges, which can happen with some horizontal-baffle pads. The MegaMat Ultra’s tricot polyester top fabric is another highlight: soft, velvety, and notably quiet when shifting positions at night.
I also appreciated how stable and supportive the pad felt. I never bottomed out, even when sleeping on my side, and the surface didn’t feel bouncy or uneven. Despite its weight and bulk, the Exped MegaMat Ultra is a compelling option for short backpacking trips where comfort is the top priority, and I wouldn’t hesitate to bring it along for car camping either.
With an R-value of 4.4, the MegaMat Ultra lands squarely in the middle of the warmth spectrum and works well for most three-season conditions. I slept comfortably in temperatures dipping into the low 30s when pairing the pad with a 15-degree sleeping bag and never felt cold from the ground. For mild shoulder-season trips, that level of insulation is perfectly adequate—but the MegaMat Ultra isn’t built for true cold-weather camping. If you expect sustained freezing temperatures, a pad with an R-value of 5.0 or higher—like the Nemo Tensor All-Season (5.4 R-value, 14.1 oz.)—is a better bet.
Where the MegaMat Ultra falls short is efficiency. At nearly 2 pounds, it sits near the bottom of the warmth-to-weight spectrum and is the heaviest “backpacking” pad we’ve tested at Better Trail so far. That weight alone will give many backpackers pause, especially those trying to keep their packs light for long days on the trail. In other words, the issue isn’t warmth—it’s the tradeoff required to get the MegaMat Ultra’s exceptional comfort. For ounce-counters, this isn’t the pad; for comfort-first campers, it may still be worth it.
For how thick and comfortable it is, the Exped MegaMat Ultra actually packs down smaller than I expected. It’s still bulky compared to most inflatable backpacking pads, but not quite as large as you might guess given it’s inflated size. Rolled up, it measures about 10.6 by 6.3 inches. For comparison, the Nemo Tensor All-Season packs down to about 10 by 4 inches, while the Therm-a-Rest NeoLoft is closer in size at 9.5 by 5.7 inches.
One nice touch is the MegaMat Ultra’s roll-top stuff sack, which makes packing much easier than with many backpacking sleeping pads. The generous opening allows you to get the pad inside without too much careful rolling, and then you can compress it down to a smaller size. Still, the packed size is one of the main reasons the MegaMat Ultra isn’t ideal for longer or more ambitious backpacking trips. Compared to self-inflating pads like the Therm-a-Rest Trail Pro it’s definitely less bulky, but in the world of modern air pads it still lands on the larger side.
For a pad this heavy, the MegaMat Ultra is built with surprisingly thin materials. Its 20-denier polyester top fabric is among the thinnest we’ve seen in this category, and the 30-denier base also falls below the standards of many backpacking pads that use tougher 50- or even 75-denier bottoms. The construction quality itself isn’t poor, but the materials feel underwhelming given the pad’s nearly 2-pound weight—especially compared to much lighter models like the Nemo Tensor Elite or Exped Ultra 5R that use similar fabrics.
That said, in real-world use the MegaMat Ultra actually feels more confidence-inspiring than many ultralight pads with comparable materials. It comes across as sturdier than options like the Therm-a-Rest NeoAir XLite, though that may partly be psychological given its thickness and overall structure. Exped also includes a repair kit, which is a welcome addition at this price point. In the end, the MegaMat Ultra should hold up fine for typical backpacking use, but it’s not a pad I’d want to drag across sharp rock or take into especially rough environments.
User-friendliness is one of the MegaMat Ultra’s strongest traits. It has separate inflate and deflate valves, clearly labeled and easy to operate. While I usually prefer a single-valve design, I didn’t find the dual-valve setup annoying, just different. The included stuff sack also works as a pump sack, allowing you to save your breath and prevent condensation from building up inside the pad.
The Exped MegaMat Ultra also has a welded side handle, which I didn’t think I’d care about—but it made repositioning the pad in a tent noticeably easier. Overall, Exped clearly put thought into making setup and breakdown as painless as possible.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Repair Kit
Repair kits help extend a product’s lifespan by allowing users to quickly fix issues—like sleeping pad punctures or damaged inflation valve seals—rather than replace the item entirely. A green check indicates the product includes a repair kit, while a red X means it does not.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
The Exped MegaMat Ultra comes in three rectangular sizes that reflect its comfort-first design: medium wide (72 x 25.6 in.), long wide (77.6 x 25.6 in.), and long extra wide (77.6 x 30.3 in.). I tested the medium wide version, which felt spacious without being excessive. I typically sleep on standard 20-inch-wide backpacking sleeping pads, but the extra width here was a welcome upgrade—especially combined with the pad’s vertical sidewalls. The rectangular shape also allows you to use the entire sleeping surface without feeling tapered or confined, reinforcing the pad’s mattress-like feel.
Therm-a-Rest NeoLoft ($260): Reigning Comfort Champ
The NeoLoft takes backcountry luxury even further with a 4.6-inch thickness and subtly raised side rails that help cradle your body in the center of the pad. This is the reigning comfort champ in the pad world, and it’s lighter (1 lb. 9 oz.), warmer (4.7 R-value), and significantly more durable than the MegaMat Ultra thanks to its 50-denier top and 75-denier bottom fabrics. While the MegaMat Ultra wins on ease of use, the NeoLoft is the more backpacking-friendly option overall, despite being even more plush. If you want a high degree of comfort without giving up as much performance, the NeoLoft is the better pick. For more, read our review of the NeoLoft.
Nemo Tensor All-Season ($240): Warmer and Lighter
The Tensor All-Season sacrifices some plushness—it’s 3.5 inches thick and doesn’t have raised side walls—but delivers far better thermal efficiency than the MegaMat Ultra. It undercuts the MegaMat Ultra by almost a full pound (the regular wide version weighs 1 lb. 3 oz.) and packs down much smaller, all while boasting a significantly higher R-value of 5.4. That’s good enough for snow camping in moderate winter conditions, and the Tensor is also a touch more durable if you’re sleeping on rough ground instead. The MegaMat Ultra is undeniably more comfortable, but for longer trips or harsher conditions, the Tensor is a smarter, more versatile choice. To learn more, check out our Tensor All-Season review.
A backpacking-friendly spin on Exped’s famously plush camping mat, the MegaMat Ultra doubles down on comfort with a 4-inch thickness, velvety tricot surface, and supportive vertical sidewalls. It delivers some of the best sleep you can get in the backcountry—just be prepared to carry a bit of extra bulk to enjoy it.

We think the Nemo Tensor All-Season is the best all-around backpacking pad on the market. It lies at a near-perfect nexus of weight, cushion, and warmth. However, it’s a bit too heavy for militant ounce-counters.

Comfort-first backpackers who don’t mind carrying extra weight or car-campers who want an easily stowable pad will get along well with the Exped MegaMat Ultra. You’ll be glad you carried on short overnights or group outings when you want to max out your sleep quality rather than your miles. It’s not built for ultralight missions, long-distance trekking, or use outside of prime hiking season, but if your goal is to wake up feeling rested rather than counting ounces, this pad delivers.
