Exped Synmat UL Sleeping Pad Review
A lightweight, inflatable 3 season sleeping pad from Exped, the Synmat UL features synthetic insulation that takes the r-value up to 3.3, with Exped subsequently rating the pad warm down to around 25 degrees Fahrenheit. The Synmat UL is available in 4 sizes: small, medium, and the medium wide and long wide – the latter 2 offering a width of just over 25 inches, compared to the standard 20 inch width of the small, the medium, and most other sleeping pads on the market.
The sleeping pad features separate inflation and deflation valves that lay flat and allow for quick deflation, or easy fine-tuning of the inflation level via a convenient one way valve on the intake, which can slightly be depressed to allow a small level of air to escape. 20D fabrics are utilized and the top features a honeycomb "Gripskin" pattern designed to keep you on the pad at night. The Exped UL will weigh between 15 and 21 ounces depending on size – the Synmat UL MW here is listed at 19.9 ounces, and weighed exactly that on my scale. Also and now included with the mat is an Exped Schnozzel pump bag, that allows you to inflate the sleeping pad quickly and easily without introducing moisture from your breath into the pad. Previously one had to buy the Schnozzel separately for around $40, so the new inclusion is a nice perk. The Schnozzel can also be used as a pack liner or stuff sack. The new Synmat UL is very similar to, and has seemingly replaced the Synmat UL 7 in Exped’s lineup with a color change, addition of the Gripskin coating, and the inclusion of the pump bag. A repair kit is also included.
Synmat UL sizes (length X width in inches) and listed weights:
S 64.2 X 20.5 14.6oz.
M 72 X 20.5 16.8oz.
MW 72 X 25.6 19.9oz.
LW 77.6 x 25.6 21oz.
Testing out the Synmat UL, and in this case the medium wide (MW) version this past summer and fall, the sleeping pad proved to be about what you’d expect: a well-rounded blend of comfort, ease of use, and warmth without weighing you down. The vertical baffles, the outer 2 which are slightly larger, help to keep one centered on the pad and resist edge collapse (resulting in you falling off the side of the sleeping pad). The pad is also 2.8 inches high, so adequate comfort is provided even on bumpy ground and there’s enough height to adjust the pad even for side-sleeping comfort while keeping your hips off the ground. The warmth provided here is great for general 3-season use. I find r-values in this range to be adequate perhaps down to the high 20’s, but if the forecast calls for nightly lows in the mid 20’s or lower I like to add in a thin foam pad to combine with the Synmat for adequate warmth, or the addition of something even warmer such as a RidgeRest SoLite in the winter.
The Gripskin coating on the top of the sleeping pad, which alternates in printed intensity, seems only slightly more tacky than the rest of the fabric itself, and personally I’d prefer any anti-slip treatment on the bottom of the pad if I had to choose a side as any sliding issues I have are usually myself and the sleeping pad together on slippery silnylon tent floors. I’m not sure how much this honeycomb pattern Exped has added to the pad really helps, and a honeycomb design also existed in a more muted, and less aggressive pattern on the UL7, but it certainly doesn’t hurt either. For what it's worth, I haven't had any sliding issues with either this pad or the previous UL7 I've used except again for that occasional pad and myself sliding downhill all together scenario when pitched on less than flat ground. If noise issues are a concern, the Synmat UL is also very quiet. With the included Schnozzel inflation takes no lung power and is achieved in about a minute. The separate deflation valve dumps all air quickly and packed, the Synmat packs compact enough.
The Synmat UL focuses on lightweight comfort with a rectangular shape, and the 2 wide versions of the pad are especially appreciated as a side sleeper, or for back sleepers that find their elbows falling off normal 20 inch wide pads. To save some more weight by moving to a mummy-shaped version with the same 3.3 r-value, check out the Synmat Hyperlite, and if you mainly backpack in warmer locales you can also stay with a rectangular shaped pad and save weight with the Synmat UL LITE, with its 2.5 r-value and less plush 2 inch height. For a warmer and heavier mat, Exped also has their Synmat Winter line.
Overall the Synmat UL continues the mark set by the UL7 of offering comfort and versatility that make this a great all around choice for 3 season conditions in climates where a backpacker will face temperatures down to, or slightly below, the freezing mark. With its rectangular construction more sleeping space is offered up compared to mummy-shaped pads, and comfort is achieved for back or side sleepers both via the construction and the via the warmth the synthetic insulation provides in appropriate temperatures and for 3 season use.
The Synmat UL retails from $150 - $190 depending on size, but you can occasionally find them on sale. Find the sleeping pad here at Backcountry, over at CampSaver.com, as well as here at Amazon.
