Dura 6R

Exped Dura. It has down. I have the 6R LW. You can get a slightly lighter version which is lighter due to thinner face fabrics. Avoid StS Etherlight XT at all costs, as I have had two getting pinctures where the dividers attach. Constant flats from just lying on them. And I am not the only one. This is why I bought the Exped Dura.

Expeds seem to be durable, I really like how comfy mine are also

I have the dura 6r, and ultra 5 mummy which hasn’t been used yet, the dura pad seems insanely durable although the ultra seems like it will be fine for durability also, seems like they are known for reliable sleeping pads so easy to reccomend

I've always found exeds comfortable and warm. Have an old down mat 5m (discontinued) and a Dura 6r. Yeah the dura is heavy but it is durable, down filled and very comfortable. I am recovering from spinal injuries and my temperature regulation is bollocked now I'm on blood thinners. I can save weight elsewhere.

I've had four Expeds. Still have two. Both have the built-in pump. One has synthetic fill. The other has some down insulation which makes it good for ~10F colder than without. The first two developed tiny leaks (could not find them even with submerging). They were a few years out of warranty. Exped still replaced both. I appreciate a company that stands behind their products. I also like side-sleeping. I have not used these as much as what you will. So durability...🤷

Hiker here: if space is a main concern you will want an inflatable mattress (not a foam pad). Read up on R-values. Decathlon make a cheap mat that is small and comfortable, but is not warm at all. Exped makes a mat that bigger but also involves down, and is very warm. There are many options in between. Bagwise consider your ability to keep it dry. Down is better in any way except when wet. Then syntheric is your option.Absolutely do not trust the ratings on a bag. Go at least 10c lower on the comfort rating. You will be hungry, and therefore cold. I love me a Nemo spoonshaped bag, which is ideal for a side sleeper.

Exped makes some great pads. I got mine for weight and pack size and it’s the most comfortable pad I own

When I got an exped downmat. It seemed like a lot of money at the time - light weight- folded up to the size of a water bottle and damn it’s comfortable- more comfortable than any camping pad I’ve ever used

Exped makes a great mat. But you might want to look at the thicker thermorest pads as an option as well

Exped downmat is the most comfortable I have ever used. I got it for backpacking and it quickly became my favorite camp pad

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.
