NeoAir XLite MAX SV

Was it the wide version of the Xlite? I have an old, since-discontinued Xlite Max SV which is similar to the Xlite XNT Regular Wide - it seems to be both thicker and wider than the Xlite of old. Normal mummy sleeping pads are no good for me but wide ones are much much better for things like arms going numb!

The younger me did and I still find it comfortable enough for a few days.  It's what I used for years after changing from Z lite and flat CCF in the 2000s It's actually my second as the first one was replaced under warranty in 2010. Longest I've used it in recent years was for 6 days. But mainly I just use it for some summer overnighters these days.     Although it isn't near as comfortable as the neoair Xlite SV regular max  I  have mainly used since 2018.  

I have the old neoair xlite, not my favorite but I hear the new one is a lot better. However, since you said you’re pretty new and the quarter pound difference in weight isn’t a concern, I’d go for the one people say is more comfortable, the tensor. I can’t imagine you’ll regret it, though on this sub you’re always going to get the recommendation to go with the lightest option

I'm a side sleeper also. I have a NEMO Tensor wide, Trekology inflatable pillow, Enlightened Equipment Enigma quilt 20°. If the temp will be below 32°, I'll put my 50° Double Diamond quilt inside the Enigma. I'm very comfortable with this setup. I typically stay wrapped up in my quilt and grudgingly get out in the am when I can't hold my pee any longer. When I had a Neoair Lite I had to get up before dawn because I simply couldn't stand the discomfort of laying on it for another minute

I never bought the standard narrow ones, I would probably be constantly rolling off of it. I even got the max version of the termarest which has a rectangle cut instead of the mummy cut because I feel like it would be too tippy otherwise. Being exclusively a side sleeper.
