Big agnes Rapide SL is my favourite pad. I had it's predecessor, QCore SLX and it lasted me a decade and we camp ~50 nights a year all in all seasons and all different kinds of trips.
I’ve had a big Agnes q core SLT (like green) r value around 4. It was amazing. Lasted two seasons, then started a slow leak that was not able to find. I ended up throwing it out but 10/10 would buy again. I’m a side sleeper/stomach sleeper and it was perfect for me. 5’8 200lb
I had the BA Q-Core for a few years until it too developed a slow leak. Thought I had maybe punctured it during a desert trip (thorns, needles and such). Did a soap smear to check for leaks. Turned out to be a material separation between the valve and the air mat portion. Glue just gave out, I guess. Called up Big Agnes and sent them an REI screenshot of my purchase date. BA was cool enough to send me a replacement of the Q-Core (discontinued) with the Rapide SL (current equivalent). Can’t say that either air mat is “ultralight,” but they are warm (good R ratings) and comfortable. As a 3-season High Sierra hiker, sleeping through very cold nights near glacial lakes is a big deal for me. Big Agnes makes great mats, sleeping bags, and tents. Their stuff is made to be durable without making comfort a secondary consideration. Yeah, I’m a fan.
Big Agnes Q-core, they make a wide / long one with a Decent R- value that still rolls up to about the size of a Nalgene. About 3 - 4 inches thick I believe.
I’ve had an Exped DownMat for several years. It’s amazing. My last sleep setup was a Big Agnes bag with their Q-Core pad. Agree, too narrow and low R value. Sold them both and got the Exped. I’ve slept in my truck bed, on a plywood deck, many times. The Exped is pretty damn nice, and I’m a 225 lb side sleeper. Do it, OP, you’ll be glad!
I just went through this. I’m 6’ 260 pounds (muscle of course). I went with the big Agnes SL wide long. I browsed the others. Sleep and warmth are important. Be my first trip for canoe back country this weekend.
