Klymit Klymaloft Peak XL Review: Fun Idea, Middling Execution
The Klymaloft Peak ($220) attempts to combine the plush comfort of a foam sleeping pad with the compactness and packability of an air mattress. It’s one of the thickest mats on the market, and offers solid durability and insulation. That said, we found that the mostly air-based construction means its cushioning and comfort can’t match that of the self-inflating mats we’ve grown accustomed to in this category. Pair that with a painstaking setup process and a few awkward design choices, and the Klymaloft Peak is lackluster at best.

Klymit Insulated Klymaloft Peak XL
For this season's top models, see our guide to the Best Camping Mattresses.
The Klymit Insulated Klymaloft Peak XL is one of the thickest and most unique pads I’ve used, but its comfort doesn’t quite live up to its impressive profile. The design combines an air mattress base with a foam topper that covers about three-quarters of the sleeping surface. The foam itself feels plush and inviting—similar to a mattress topper you’d find at home—while the uncovered section feels more like a backpacking pad, with a firmer, plasticky finish that’s less comfortable against the skin.
When it comes to thickness, the foam-topped area measures 5 inches, while the exposed portion is about 4.25 inches, making it the thickest mat I’ve ever used. That, combined with a sleeping surface of 78 by 29 inches, puts its dimensions in the same ballpark as premium mats like the Exped MegaMat LXW (77.6 x 30.3 x 4 in.) and Nemo Roamer RXW (80 x 30 x 4 in.). I’m 5-foot-10 and never felt tight on space, though the rounded edges (rather than vertical sidewalls) cut into the usable area a bit.
What’s more middling is the actual comfort. On my back, I had no issues and felt fully supported. Side sleeping was less successful—while I was fully isolated from the ground, my shoulder tended to compress against the firmer air layer, making it harder to get comfortable. You’re not going to get the same consistent, body-conforming support as self-inflating mats like the 4-inch-thick Roamer or the REI Co-op Westward Dreamer, which, while thinner, have a more cohesive, mattress-like feel and still fully isolate you from the ground. Even so, compared to my 2.5-inch-thick REI Co-op Campwell—which I’ve bottomed out on—the Klymit Insulated Klymaloft Peak XL is a clear step up. It’s the most comfortable air mattress I’ve used, but it still falls short of what the best self-inflating options can offer.
With an R-value of 7.0, the Klymaloft Peak delivers solid insulation for most three-season camping, with enough warmth for early winter use as well. It’s not the warmest mat out there—that title belongs to options like the Monstamat King with a 10.5 R-value—but it still matches up with other top-tier camping mattresses like the MondoKing and Roamer.
My testing included a trip to Southern Utah with overnight temps in the high 40s to low 50s and a light breeze, where I stayed comfortably warm throughout the night. I was using the Kelty Eclipse 15 and actually had to keep it partially open to avoid overheating. I saw similar results testing it on my apartment floor, with temps in the 60s and a fan running. Paired with the REI Co-op HunkerDown 20, I again stayed plenty warm without needing to fully zip it up.
That said, while I trust this mat to keep me warm on shoulder-season trips, I’ll still be reaching for a self-inflating option like the Roamer in colder conditions. Even with the same rating, there’s something about the consistent insulation of an all-foam construction that feels more reliable than the Klymaloft Peak’s hybrid design. Realistically, though, unless you’re camping in the dead of winter, it provides more than enough warmth.
The Klymit Insulated Klymaloft Peak XL didn’t make the best first impression in terms of build quality, but it held up better than expected during testing. When I first inflated the mat, only the foam topper felt high-quality—the rest of the air mattress had a slightly budget, plasticky feel. Even the included repair kit (or should I say, the single strip of Tenacious Tape) reinforced my initial impression.
That said, the specs tell a more reassuring story. The thick, 75-denier polyester fabric is right in line with what I’ve seen on many camping mats, and across a couple of nights of use—including one on rocky desert ground in Southern Utah—I didn’t experience any punctures or failures. The single flip valve with a snap-on cap also worked as intended. While it released a bit of air when I overinflated the mat, it stayed leak-free throughout the night.
Still, I trust foam-based self-inflating mats more on rough ground. In my experience, they conform better to uneven surfaces, while air mattresses remain more rigid and prone to damage. As a consolation, if it does deflate, the foam topper still provides some cushioning, which is more than you can say for most air-only mats.
The Klymit Insulated Klymaloft Peak XL is the most cumbersome sleeping pad I’ve used—full stop. Unlike self-inflating camping mats, you have to blow it up from its fully deflated state. And compared to backpacking pads, it’s much larger, which means you need to push a lot more air into it to get it to size. Using my lungs, it took around 35 deep breaths to fill. The inflation sack (which doubles as its stuff sack) does cut down on the effort, but it still requires more time and energy than I’m used to. Luckily, the sack works well—the valve connection is secure, and it’s easy to push air in—but it’s not especially efficient given the mat’s size.
The valve placement doesn’t help matters. It’s located at the bottom of the mat, which means you have to flip it over or reach underneath anytime you want to inflate, deflate, or make adjustments. I understand the design constraint with the foam topper, but I’d much rather have it at the mat’s exposed foot end, where I could access it without as much wrestling. On top of that, the valve cap is surprisingly difficult to snap shut—you have to align it perfectly and really force it into place. It’s noticeably harder to close than the caps on my Roamer or Westward Dreamer.
There are a couple of bright spots. Since it’s air-based, it’s easier to fully deflate than most self-inflating designs. The roll-top bag also has a wide opening, making it fairly manageable to pack away, even if you do need to fold it in half to fit. Overall, though, you’ll want to budget extra time and effort to get this mat ready for bed.
Klymit notes that the Klymaloft Peak can be used as both a backpacking and camping mat, but it ends up landing in an awkward middle ground—especially when it comes to weight and packability. The XL version I have weighs 4 pounds, 6.4 ounces, and packs down to 9 by 16 inches. Considering its full size (78 x 29 x 5 in.), that’s impressively compact—a clear benefit of its mostly air-based construction.
That said, it’s still too heavy and bulky to seriously consider for backpacking. Even the smaller Regular version tips the scales at over 3 pounds and doesn’t pack down particularly small (8 x 12 in.). When lighter and more compact comfort-forward options like the Therm-a-Rest NeoLoft exist at around 2 pounds, it’s hard to justify carrying the Klymaloft Peak into the backcountry. At the same time, there are more comfortable car-camping mattresses of a similar size. My Roamer, for example—while at 76 by 25 by 4 inches is slightly smaller—is also lighter (4 lb.), more compact (14 x 8.5 in.), and offers a noticeable bump in comfort.
At least packing up the Klymaloft Peak itself is relatively easy, requiring just one roll to fully expel the air. And while you do need to fold it in half to fit into its stuff sack, you’re not fighting it the way you would with a fully foam self-inflating mattress. But overall, its weight and packed size land in no-man’s-land for me.

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.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
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.
Dometic Highrise 10 ($200): A Pad That Knows Itself
Unlike the Klymaloft Peak, the Dometic Highrise 10 knows its lane. Firmly a car camping mat, it weighs over three pounds more (7 lb. 7 oz.) than the Klymaloft Peak and doesn’t pack down nearly as small (30 x 16 x 9 in.). But with the added heft comes clear improvements. Its 9.0 R-value outclasses the Klymaloft Peak’s 7.0, and despite a 1.1-inch drop in thickness, it’ll still prevent you from feeling the ground while delivering a more plush, bed-like sleeping experience. And though you may have to wrestle more with the Highrise 10 to fully deflate it, it requires much less effort to inflate. Plus, the valves on the headwall are far easier to access and use than the Klymaloft Peak’s flip valve on its underside. For maximum car-camping comfort (and $20 in savings), the Highrise 10 is an easy recommendation. For more, read our review of the Highrise 10.
Nemo Flyer Cloud LW ($200): A Better Hybrid Mat
The Nemo Flyer Cloud LW is another mat that splits the difference between car camping and backpacking, but opts for a fully foam-based, self-inflating design. Its 76 by 25 by 3-inch dimensions don’t offer as spacious or lofty a sleeping surface, and its 20-denier polyester fabric requires more care, but the tradeoff is a mat that’s both smaller (8.5 x 12 in.) and lighter (2 lb. 11 oz.), making it a more viable backpacking option. As for comfort, the Flyer Cloud is firmer than the Klymaloft Peak’s foam topper, though it’s easier to make micro-adjustments to its inflation level, as its valve is located on the mat’s surface instead of its base. Ultimately, if you prioritize space, the Klymaloft Peak has the edge, but the Flyer Cloud is the better (though still not great) hybrid backpacking and camping mat. For more, read our Nemo Flyer Cloud review.
This somewhat unconventional mat pairs a sturdy air-mattress base with a foam topper for added comfort and support. Unfortunately, it’s plagued by an identity crisis—it’s too bulky for backpacking but not a comfort leader—and features a few questionable design choices, including a laborious setup process.

Portability is the name of the game with the Flyer Cloud, boasting an impressively compact packed size for a self-inflating camping mat. As for the rest of its features—including comfort, durability, and warmth—one word sums it up best: mediocre.

Is the Klymaloft Peak for You?
The Klymit Insulated Klymaloft Peak XL makes the most sense for campers who want a thick, warm mat that packs down relatively small for what you’re getting. It’s not the best choice if comfort or ease of use are your top priorities—there are better, more cohesive options that are easier to set up and sleep on. But if you like the idea of a spacious pad that keeps you well off the ground without taking up too much room in your car, it’s a compelling middle-ground option.
