r/CampingGearSleeping pads for short people
5 months ago

Are you winter camping? An R of 3.4 is sufficient even just below freezing. Sea to Summit makes short pads.

I found mine really didn't live up to the R rating. I was freezing even at +7, and I normally run hot. I wonder if the wet saturated ground had something to do with it, but I never had issues like that with my old MEC self-inflating.

r/UltralightSleeping pad for bad back
8 months ago

I have a previous back injury. I find the Womens S2S Etherlight to be the most comfortable, though the least warm. Next for comfort is the Nemo All Season, as well as the Nemo Tensor. In comfort, they are both just slightly less comfortable than the S2S. Both are warmer than the S2S. I have used the ExPed Hyperlight pad for about 40 nights. I believe this pad has been replaced with the newer version. Mine was a 2.8R value. For me, the warmth was equal to the S2S pad. It was not an uncomfortable pad. It just wasn't as comfortable as the S2S and Nemo pads. I tried the Thermarest NeoAir Xlite. My lower back ached when I used the pad. It just didn't have the support I needed. I wish I could use it as it has great warmth to weight ratios. I used the wide versio pads for each of these, though the Exped was a mummy MW version I would assume what is comfortable for me may not translate to you as your back injury may be different than mine. My injury involved the lower back. I have slept in a hammock a few nights and never experienced back pain.

I have the summit ether light wide, started using when 300 lbs 5’5. It was the 4th pad I tried and the one I have kept using and would recommend. Haven’t tried the others though.

r/UltralightVery poor sleep on the NeoAir X Lite NXT. Recommendations?

I also love my Etherlite rec. large. I have around 100 nights on it, and I sleep better than at home. But I am in the opposite boat now, trying to find something lighter. They are heavily discounted right now (for example at Bergfreunde, but that ships from the EU), so it might be worth picking one up to try.

OT, the North American clearance price on the remaining XT mats is incredible. $59 for the women's XT.

r/WildernessBackpackingHow much better are “nice” sleeping pads?

I went with the S2S ether light XT wide. I think it is 4" / 10 cm thick whereas my previous thermarest prolite was 5cm... My hip needs 10cm. At the minimum.

Fellow side sleeper! I'm female so I have hips and I NEED good compression. My shoulder felt jammed up in the Nemo Tensor All Season. The REI Helix was the best once I was on my side, but I felt like I bottomed out when rolling over and also if it wasn't fully inflated but definitely check this one out. Currently I'm on an Sea to Summit Ether light XT (fem version) because I found it on sale and I love it! It's similar in comfort to the Big Agnes Rapide SL (my husband has the big agnes, but it's super expensive so I went with the S2S because I was getting desperate).

r/bicycletouringBest winter sleeping pad for comfort, warmth, and durability?
6 months ago

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.

I like my ether light xt by sea to summit. But it’s really the only decent one I’ve ever tried so. Or much to compare it to.

The sea to summit is 10cm thick, which is amazing for it's size and weight. But it's made of a noisy fabric
