Hi there…
I’m a z-rest user myself – one of those closed cell-foam pads that folds up like an accordion. Not cushy, but lighter than a Thermarest. I’m not an ultralighter, but it’s one of the ways I choose to cut down on pack weight.
Over the past three years that I’ve been using the z-rest, I’ve figured out how to maximize my comfort – using the word loosely – including using a stuff-sack stuffed with clothes as a pillow. Sometimes I put that stuff sack on my backpack as extra cushion, or I prop my feet on the backpack if I have plenty of clothes for an ample pillow. I look for the softest piece of ground possible (I know … duh!), and I do 1/4 turns OFTEN. I’ve “learned” how to do this in my sleep, I guess. But, still, I’m sure it’s nowhere near as comfortable as a Thermarest. I guess it’s all about how much discomfort you can take versus pack weight and other factors – ie. I like that the z-rest can get wet without soaking up water. I just shake it off. I don’t slide off it like I’ve seen some people do with Thermarests. And no problem with air leaks. BUT many people love Thermarests and wouldn’t think of using a Z- or Ridgerest. Thermarests are more expensive, but, if you can, give it a try. A good night’s sleep, especially on a long backpacking trip, is so important.
As to whether you “toughen up,” ummm, in my case, I’d say yes. Or “get used to it” would be more accurate.
