"I have bad discs in my neck and back, and can still side sleep on an Exped. ... They are a gamechanger for me."
"They are the best mattress for camping I have ever used. ... Even weighing 230lbs, side sleeper, I would have a tough time touching the ground through the mattress."
"I have a exped also and its more comfortable than my normal mattress."

"I recently slept on my Exped, straight on the ground (but in a tent) at 15⁰f and had no issues with the cold."
"It’s super comfortable, I don’t get any cold spots at my arms or feet."
"They are not phony in the sense that the insulation ratings are way off. ... I camped in freezing temps for the last 5 years and am very toasty on every trip."

"I've used my Exped for 500miles. I've never had a problem with it. ... Personally, I would only buy Exped or Big Agnes sleeping pads because they're the only ones I've never seen leak."

"the exped still makes noise ... the noise caused by the sleeping bag sliding around on the pad ... I turn over nonstop all night long and am insanely sensitive to noise."

"it is bulkier and heavier for the same warmth rating."
"The Exped is definitely a bulky mattress style, though."

"Over time, the Exped began to leak ... As best I can tell, the rubber lining inside the fabric begins to slowly degrade and develop pinhole leaks. ... You never hear leaking air. You just wake up in the morning with your hip touching the ground (I’m a side sleeper)."
"Mind you, my Exped mat has never been the same since I camped in a prickle patch."
"Expeds CAN leak"

"on Exped pads, DO NOT simply pull the flap to open the valve. BE SURE to hold the part of the valve that is permanently attached to the pad fabric separately so that the forces of opening the flap do not tear the valve out of the fabric."

My exped 9cm is fantastic. I have the long wide synthetic one. They also make a down one
r/bikepacking • comfortable sleeping pad for a large person - 188cm tall, 52cm wide shoulders, move around a lot at night ->My exped is a piece of magic.
r/bicycletouring • Sleeping pad recommendations ->I have a exped 9 cm thick pad. Mine is the synpad, it is a bit larger than the down equivalent when folded up, but it is really super comfortable, and with a great R rating
r/bikepacking • Overwhelmed sleeping pad purchase ->My exped is really comfortable and warm
r/bikepacking • Recommendations for sleeping pad ->I've used it for about 80 days over several trips. It's a very robust build.
r/bikepacking • Recommendations for sleeping pad ->My Exped LW9 is a dream
r/bikepacking • Durable thick and wide sleeping mat? ->What country are you in? It may have a different name. I'm in Australia. There are two. Exped downmat XP 9 LW Exped synmat 9 LW I have the synmat. If l was backpacking l would have got the down one. I have no idea what XP means, but LW is long wide. Good luck
r/bikepacking • Durable thick and wide sleeping mat? ->My Exped SynMat 9 Deluxe air pad is still going strong 15 years later. Yes, it's worth it.
r/CampingandHiking • Is an expensive sleeping pad worth it? My pool float beat the cheap ones. ->Most will tell you “you need an underquilt”… but if you prefer the little extra structure/support from a pad, like me, then a pad will do JUST FINE! I have an under quilt, but prefer and pretty exclusively use an inflatable pad. I think what works best is a mummy shape with rounded corners and tapered foot end. I use an older exped synmat LW (long wide) mummy shape pad, basically same as current exped 3R pads. It fits great in my hammock (hammock gear circadian). It’s super comfortable, I don’t get any cold spots at my arms or feet. Would also work great if I ever needed to ground camp. .. you don’t “need” and under quilt, if you have a pad that works well with your setup.
r/Hammocks • Any good hammock, sleeping pads like the Klymit hammock V. ->I really like my Exped Synmat 9. It’s not produced anymore but they have a lot of other models.
r/motocamping • What‘s the comfiest (ultralight) camping mat for dual sporting? ->Exped all the way. Love my green whatever name it is, it's insulated, so it's nice in cold months and works good in summer months.
r/motocamping • Sleeping pads? ->I have an Exped Synmat and it's quite comfortable. It's more "air mattress" than my Thermarest Prolite Plus but more comfortable. So much so I'm insisting my wife use my Synmat mattress instead of her existing Thermarest on our next trip. I can handle the lesser one (I hope). I think basically if you're spending some money it's always going to be more complicated than "air mattress". I think OP means a classic vinyl sack filled with air. They tend to have poor support, zero vapor management, and are cold (because air convection inside the mattress takes all your heat and moves it to the ground).
r/camping • Couples: what do you sleep on (NO air mattresses, I resent them so much) ->G'Day Practical, I've had an Exped Synmat which I recently replaced with an Exped 5R (I haven't used this yet, but it is the successor the Synmat). The Synmat lasted quite a few years and I was very happy with it. Both mats are rectangular rather than tapered so I think you will be less likely to slide off it. I certainly never had any problems, which is why I bought the 5R. Regarding sleeping bags, I have a three season bag (Exped Ultralite 300, \~300 g down) which I can pair with an inner bag (Macpac Snowflake, 130 g down). I used this combination (along with a silk inner sheet) in Nepal up to 4000 m (in accommodation) and was always comfortable. Note, you didn't mention having an inner sheet. If you do not have one, I advise you to get one (silk, not cotton). I think it is worth buying quality products from reputable manufacturers. They will last you a long time and be reliable.
r/bicycletouring • Need help choosing an ultralight sleeping bag and mat for the summer French Alps. ->Exped mats are warm and comfortable- just pick the one with a high r value that best fits your needs. I have the synmat not sure if they still make it but it has been the most comfortable one I’ve slept on
r/CampingGear • Winter foam sleeping pad recs ->Spend a few dollars more - exped has some great mats- synmat or downmat. Light, comfortable and warm in cold weather too. I justified the price based on how much a hotel costs- being comfortable is important and you will have it forever
r/CampingandHiking • Recommendations on camp sleep pads ->Exped makes some great pads. I got mine for weight and pack size and it’s the most comfortable pad I own
r/CampingGear • Sick of air mattresses - what's the best sleeping pad? ->Exped makes a great mat. But you might want to look at the thicker thermorest pads as an option as well
r/CampingGear • Sleeping pad recommendations ->Best thing for sleep is a double pad. You can sprawl out and never fall off. The exped duo long and wide is amazing. Also have the nemo quasar double, but the exped is lighter and more comfortable. Best pillow is thermarest.
r/Ultralight • Talk me into or out of a neoloft ->Get an exped airbed. I've tried a lot of selfinflating mats, but i always end up blowing them up by mouth and than have les comfort sleeping than with the exped mats and be sorry i bought them. The investment in an exped is worth it, especially the air bag to blow them up is genius.
r/camping • Is a self inflating sleeping pad better than an air mattress? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
