I went with a Nemo pad instead. This one didn't do much in the way of actually self-inflating when I tested it, and it was nowhere near as comfortable as the Nemo Flyer.

Wrong R rating

The R rating on the pad is 3.8 not 4 and it's recommended use is 3-season, not four, overall a good pad, I don't expect it to make much of a difference, just wanted to point out that the description is incorrect.

Perfect if your not worried about weight

I've used it several times

This Pad is super comfy and is really warm. The downside to it is that it weighs nearly two pounds ( in the Large ) and doesn't pack that small when compared to its Full air counterparts. This is an ideal pad for car camping and short backpacking trips where you have plenty of room in your pack and your not worried about weight. I slept super well on the pad and have had no issues with it deflating. Highly recommend getting the Large as its best used where weight and size aren't an issue and the extra size in the pad makes a huge difference if your a side sleeper or toss and turn a lot in your sleep. All in all a great pad and will continue to use on car camping trips

A great "little' pad

Honestly- it was little. maybe a little TOO little. I slid off a few times, but I should probably blame my tossing and turning as opposed to the pad. comfy, and will use again

Good for car camping

I've used it once or twice and have initial impressions

This pad was super comfortable and compacts down well. Though as others have said below, I might not throw this in my backpacking set up and opt for something smaller. Used this pad in the San Rafael Swell, so I can't attest to it's insulation in really cold temperatures, but I was warm throughout the night and the length was just right for me (6ft tall). Would definitely recommend it.

Fantastic Pad

I've used it once or twice and have initial impressions

I had the opportunity to demo this pad for a couple of nights in Escalante, Utah on the desert floor. Overall, I found the pad to be very packable and extremely comfy, more than my typical lightweight pads. That being said, I probably wouldn't throw this in my backpacking set up, I'm a stickler for optimizing space in my pack and this takes just a tad bit too much. I would, however, keep this as a go to for car camping adventures!

Continuous Improvement

I've used it several times

Having owned and loved the previous iteration of the Prolite, I didn't think the design could get much better. Well, in keeping with Thermarest design philosophy, it did. While it is not the most packable pad in the lineup, I still reach for my Prolite when I'm prioritizing comfort over weight. I will say the included stuff sack certainly helps with compression! I have used this pad at altitude and in the high desert with conditions ranging from the 30s to the high 50s. All comfortable nights of sleep. Highly recommend this pad!

Slept well, despite the hardwood floor

I slept on a hardwood floor on a recent Colorado trip with this pad. Zero complaints and honestly it's a MUCH better alternative to my other pad, which has no denting in it and is not self-inflating.

So Comfy!

I had the opportunity to go on a camping trip with my company a couple weeks ago. I took this pad and couldn't be happier with it. It doesn't pack down like a backpacking pad but it also offers way more comfort. I slept directly on the ground without a tent and this pad held up against the rocks, twigs, etc. This is a great car camping sleeping pad!

New Apex Pad

I've used it once or twice and have initial impressions

So this is the new thermarest pad and while I have not tested it in the field yet I figured I’d leave a preliminary review for any thru hikers about to start the season. Pad came in an easy to compression sack. I was able to roll it out without issue and did blow it up by mouth for the first use. I would recommend this and leave it inflated for a bit to help break it in. It was very comfortable and was not noisy like the pure inflatable pads. They do offer a wide version now however I got the regular size and fit well. If you’re bigger or concerned about your elbows be off the edge then I’d recommend the wide. It’s not much more expensive. The pad deflated well, it was a bit tricky to deflate as the pad wants to obviously re-inflate while the valve is open. So it requires some application of force. I find it easiest to roll it up once to get the air out then roll again to get it tight. It fit easily back into the compression sac. Overall given the increased R value with this new pad I’m expecting it to work well in all 4 seasons. I deliberated a lot over the purchase given that’s its new and lacks reviews, however I’m very pleased after resting on the pad for a bit. I’m also pleased with the weight of pad and the size when back in compression sac. Would really recommend for those looking for a comfortable option with a decent R value, but not the noise of a true inflatable pad. Obviously you sarifice some space in your pack in comparison. As I stated above I haven’t given it a true field test yet but I’m expecting a great performance.
