If you’re hitting the trail only 3 times a year, go with the Marmot Limelight 2P of your list. It’s better than the Kelty or ALPS and almost always includes the footprint which will save you a $30 hidden cost and keep your gear from soaking up ground moisture Alternate - Naturehike Star River 2 (20D) because it’s the budget UL king from everything I’ve tried and tested in the past. [11 Best 2-Person Tents for Camping and Backpacking](https://alaskanarrows.com/11-best-2-person-tent-camping-and-backpacking/) would be a good source for other tents in your budget range too For your sleep setup - stack a NEMO Switchback foam pad under a Klymit Static V2 and you’re set with the back support you need for your joints while actually insulating you from the ground. With that + a TETON Sports Trailhead 20 or an REI Trailmade 20 and you’ve got a legit setup that fits your $300 budget
I would not recommend a ccf pad though I take a small piece to sit/kneel on at camp. Found the Thermarest Neo-air uncomfortable and a pain to inflate; bought a Klymit Static V2 at less than half the cost and they’re definitely on to something with their design. It’s a few more ounces than the neoair. I’m a side and stomach sleeper and slept like a baby on my last 5-night trip. It seems thin at first so I was skeptical but its wide/channeled design does a miraculous job of cradling your body and distributing the weight. Honestly, best pad I’ve used backpacking in 25 years.
You’re right. It’s the V2 that’s got a 4+ R value rating
You can get a Klymit Static V for $40 direct from their website right now, which is a known brand with a warranty and roughly half the weight of that one. Or you can get a Static V2 from Amazon for $50 and shave off another couple ounces.
I have the Ampex Reland Long/Wide and have been happy with it's performance. It's the most comfortable sleeping pad I own and has kept me perfectly warm in temps down to the low-20s. I also have a Klymit static V2 that I've used for years for temps above 40. I really like the static V but if I had to pick between them I'd go with the Ampex no question, I really recommend getting the long/wide version if you can, it is much more comfortable than the standard size as you don't have your arms falling of the sides and have a lot of room to roll around.
Yeah there's basically too much bonded area with zero thickness for it to provide much insulation overall. That being said I used to use my uninsulated Static V into the 40s without issue. Big caveat that I use a full sleeping bag and not a quilt.
I've used sleeping pads from Exped, Sea to Summit, Thermarest, Klymit, and a bunch of random off brands like outdoorsman lab and ampex. In my experience all brands will hold air all night and are roughly equally reliable out of the box, the difference is the higher end brands have better support if you get a defective product. That being said, Exped makes my personal favorite inflatable sleeping pads and if you mostly camp in warm weather you can currently get their 1R from their website for $50 https://www.expedusa.com/products/ultra-1r-mummy If you go out in colder weather, add a 1/8" EVA foam pad like this one: https://www.gossamergear.com/products/thinlight-foam-pad Combine those and you get a sleeping pad that can get you down to just about freezing (in my experience) for a total weight of ~1lb and a cost of ~$80
6ft 230, slde sleeper, Budget Sleeping pads I've tried: Trekology UL80 - less than $50, 19oz so fairly heavy. Very comfortable. Not sure about durability, I've only used it 6 or 7 days in summer/fall Klymit Static V2 about $50, comfortable, durable and fairly light at 16oz. I've got about 30 nights on this. I would recommend this to anyone on a budget not looking for ultra-lite. Neither of these has much insulation, but I haven't slept cold in either. I use a sleeping bag so I'm insulated I've owned many much more expensive and lighter sleeping pads, and each and everyone has leaked after a couple of weeks. Best was a Therm-a-rest Neo-Air that lasted two months before developing a slow leak.
Insulated klymit static V2 meets that criteria and is under $100 at that. I’ve been pretty happy with this pad and know a few others who have the same experience. I bought it cause I read reviews that it was good for side sleepers. As a side sleeper, I can attest that it does in fact work really well. Not sure I would spend piles of money on a sleeping pad now that I’ve carried this one. It’s R4.2, 20oz, 2.5” thick, easy blow up/deflate system, has been rock solid for more than 2 years now on dozens and dozens of nights both on the trail and just regular camping trips.
