Astro Series

I love my Nemo Astro

R value of 2.6 is not bad, it's still an "insulated" pad though, I'm hoping to get something with this level of quality, packability, and comfort without the added insulation. Nemo is a great brand though, I have a few items and I love them (I wish they would get back to me about my warranty though 🙄)

I cut a Nemo astrolite pad in half and gave my girl her own WM megalite quilt to sleep on. She’s ten years old, and I just can’t make her sleep on a thin foam pad in her golden years. 

Ah yes that was a common issue with the older ones. I have the newest one and fear it might have the same problem. Slept on it only one night but felt some cold spots where the most pressure was. Meanwhile it's R4.1 rated so should definitely be suitable for 3 season use. However my Nemo Astro Insulated feels warmer with mylar film in it

Dump the nemo Astro out of the running: Its R value is listed at only 2.6 and it's 1lb 11 oz. The others are warmer and lighter. Plus it's a 20" wide pad. I don't know why, after all these years, we don't have a 23" option - more comfy than a 20", which tbh sucks but lighter than a 25". But I digress. We don't. It's either 20" or. 25". 25" is a way nicer nights sleep and Some of the pricier pads you've chosen here come in at this size for a very similar weight and significantly more warmth. And since all of these options are in your price range, according to you, then I'd say dump the nemo Astro. By comparison, the other Nemo pad, the extreme conditions, is an 8.5 r value and the Long and Wide size Is only 1 lb 10 oz. That's WAY warmer and more comfortable. It may suffer from a little less durability. Rab is a REALLY solid brand. I would categorically buy anything they made, and I have a lot of Rab gear. So if you are ok with a 20" pad, then this might really hit a sweet spot for you if price is an issue. I would forever and always buy a 5.5 R rating pad over a 2.6. The Thermarest has a very, very good 7+ R rating while also being very light for a long wide mat at 1lb 8 oz. Kinda seems like the winner to me. Again, the question is durability and how you will use it. If you expect to be at altitude or in cold weather or shoulder season, you'll want at least a 5 R value. Fyi Exped pads are really super too. I rock an older down filled Exped mat that's been good to me for a very long time now. R rating of 7+ - Have taken that into 20 degree temps on Mt Rainier for winter camping etc.
