"it did get punctured on my last trip."
I have both of these coincidentally. The plan was to take my Insulated on trips I’m packing light, and my Large S.I on trips where weight/size isn’t a factor. Both comfortable, but I personally enjoy the SI’s flat surface over the Insulated with their Air spring design. The SI has a R value of 4.1, and the insulated 4.0 so they’re basically the same for warmth. If size wasn’t a factor I’d go S.I if I had to choose one. Can’t go wrong with either one of these IMO
Exciting! I always imagined the SI would be easier to patch on the fly while camping. I also recommend one of the larger ones if you can, cuz It’s no fun having your arms fall to the ground if you’re a back sleeper. Happy camping!
sea to summit has hybrid inflatable/foam pads. I have a comfort si that is around 4 r value.
I’ve slept on the Comfort Plus for a couple dozen nights and just picked up the Ether Light XT Extreme after having a couple nights of bad hip pain using the comfort plus. I haven’t slept on the Ether Light yet, but it seems to be much more comfortable for side sleepers like myself. I got the regular sized Ether Light XT Extreme and have the rectangular Comfort Plus. The Ether Light is a lot smaller when packed and I’m sure the non-extreme would be even smaller yet when packed. I also think the 3” thickness of the Comfort Plus is slightly exaggerated, seems to be less than that, but that’s anecdotal. The Ether Light is markedly thicker and fellow side sleepers seem to really enjoy it. I think both are pretty nice, but based on the necessity to sleep on your side and reduce packed size/weight, would recommend the Ether Light.
The Ether Light XT was very comfortable, would definitely recommend if you’re primarily a side sleeper. If not, and you will be primarily car camping, the Comfort Plus will do well. The Ether Light’s are not on sale anymore either which is a bit of a bummer.
I had the Sea to Summit Comfort Plus SI Insulated for a while, though unfortunately, it did get punctured on my last trip. I am currently researching what to replace it with. My one qualm with the Sea to Summit was that it was relatively heavy, so I might switch it up, but I don't know if it's worth sacrificing the comfort for the weight. If I don't get the Comfort Plus again, I'll probably go with the Nemo Tensor All-Season Ultralight, which is supposed to be quite comfortable, but almost half the weight. My primary source for researching all of my backpacking gear is Outdoor Gear Lab. Their reviews and comparisons are very well done.
We use fold up carton type mats as our base. Then in our tent we have Sea to Summit self-inflating bed rolls. Our kids have the same base and use Therm-o-rest self-inflating ground mats. We find as long as we stay on the self-inflating mats, we’re pretty comfortable. The ther-o-rests are almost 20 years old and still in great shape. We upgraded to Sea to Summit because they fold up so small for backpacking
I have started using a Sea to Summit comfort plus si. It’s heavy for backpacking but I decided the weight penalty was worth it for better sleep. My inflatable pads all slept cold and were all noisy. It has been on closeout so likely still good deals can be had on it. (I used a coupon from REI for mine)
Sea to summit inflatable foam sleeping pad, believe me it's worth it, I won't waste my money on these
I’m a side sleeper as well and I stopped using my Nemo tensor so much because of the potato chip bag noise effects heh. This past winter, I’ve used the Sea to Summit comfort plus. It is easily the most comfortable pad I’ve ever used for side sleeping. And inflates and deflates easily. Highly recommend!
I'm a big fan of the sea to summit pads. If I was buying now I'd buy the comfort plus. 6'5" 250ish side/stomach sleeper
I had the same challenge recently, as in buying my first pad. I went with Sea to Summit comfort plus in the end. Paid 70 quid with delivery. I tested it in a 2 day camp and was impressed by the quality and “warmth”. But it is to the heavy/bulky side.
I recently got a Sea to Summit comfort plus and used for the first time at 1 degree and I was nicely warm. I got it for around 70 quid. It is to the heavy side though and in the summer I intend to buy a light mat but for the price I was very impressed with the quality and warmth.
