Exped Ultra 6.5R Sleeping Pad

This is where the Ultra 6.5R separates itself. The biggest differentiator is the slightly stretchy 20-denier polyester top — it's noticeable, it lets you sink into the pad, and it feels soft against skin rather than sticky or plasticky, even if you're not wearing much.

The vertical baffles do a lot of work here too. Unlike horizontal baffles, they don't create pressure points, and combined with the stretch in the fabric, pressure relief is excellent — no numb arms, no hot spots. Stability is solid as well: the outer tubes are slightly thicker than the middle ones, which is meant to cradle you toward the center. I don't notice the cradling effect much, but edge support is good regardless.

At 9 cm (3.5 inches) thick, it's not the thickest pad on the market, but I've never bottomed out on it, and I think it's a thickness that works for most people.

One underrated comfort factor: the size range. Rectangular or mummy, regular or wide, short or long — you can genuinely customize this pad to your body and sleep style, and that matters more for comfort than it gets credit for.

The Ultra 6.5R carries an R-value of 6.9 and is advertised as an all-season pad good for temperatures below freezing. The insulation approach is genuinely clever: a layer of synthetic fiber glued to the top of the pad, with reflective film glued beneath it — suspended from the top rather than filling the whole chamber. You don't need insulation throughout the entire pad, just near your body, and this is an efficient way to save weight while staying warm.

In practice, I took it down to about -6°C on frozen ground before feeling heat loss. Some people will be disappointed that a 6.9 R-value doesn't sleep warmer — but R-value is not the be-all-end-all metric it's often treated as. Judged by warmth for its weight, -6°C on a 551-gram pad is genuinely impressive, and it lines up with how Exped actually advertises it. Credit to them for marketing real-world performance instead of leaning on the number.

551 grams measured for the regular wide rectangular version (6 grams over spec), and the mummy regular/wide is advertised at just 425 grams. For a pad with this warmth and comfort, that's excellent — this is a true ultralight pad that doesn't feel like one when you're lying on it.

The pad packs up small and stores easily, and the included inflation bag works well. The valve system is my biggest gripe. You get two separate flat valves — one for inflation, one for deflation. The deflation valve dumps air fast, which is nice at pack-up time. But both valves sit on the bottom of the pad, which makes midnight adjustments a pain: if the temperature drops and pad pressure falls, or you want to soften the pad a touch, you're digging underneath yourself to find the valve.

Two valves also means added weight, complexity, and more points of failure — and valve welds are exactly where I've seen pads fail. A single one-way valve on the top corner of the pad, like other manufacturers use, is simply the better system.

The Ultra 6.5R uses a 20-denier ripstop polyester shell with TPU extruded onto the inside to create the air chamber, and welded baffles separating the air chambers. The construction is simple, with fewer welds than pads that use many small weld points — and long single welds per baffle are exactly what you want, since small welds are where I've seen other brands' pads fail.

Exped had a reputation for weld failures five to ten years ago, but the Ultra line has been around a few years now and seems to have put that behind them. I've had zero issues across multiple Ultra pads, and reviews online back that up. I'd now put this among the more durable ultralight pads on the market.

One of the quietest pads on the market. Despite having reflective film inside, there's no crinkle factor at all, and the soft stretchy polyester has none of the rubbery squeak you get from some pads. Tossing and turning in a tent at 2 a.m., this pad won't wake your tentmates — or you.
