Neoairs are good for their intended use: superlight backpacking. They are a bit narrow and noisy and a bit of a faff to blow up (they don’t self inflate at all). They are lighter than a normal Thermarest and much smaller pack size. They are also not as robust as normal Thermarests.
For car camping I’d go for a Fat Airic or similar – fantastic comfort but too heavy and bulky to carry.
For ‘normal’ duties you need a Thermarest Prolite or whatever they are called now. More robust than a Neoair, mostly self inflates and quieter.
So, you need to buy three mats now 🙂 Time for the perenial ‘original Thermarest vs the wannabe’ debate. I have 4x normal Thermarests, a NeoAir and an Alpkit Fat Airic. The only one that’s been a problem is the wannabe. If there is a problem, Cascade Designs (the Thermarest maker) warranty is legendary.
