Product Description

Product Description

This is our lightest and most compact closed-cell pad with all-new foams - softer on top for more comfort and denser on the bottom providing better durability. It's the best choice for people seeking sleep-any-where, on any-thing durability and comfort


Therm-a-Rest's Fast & Light mattresses allow you to experience unrivaled comfort without compromising your goals. Weighing less and packing smaller than other mattresses, they facilitate the kind of high-speed, low-weight camping experience sought by alpinists, adventure racers, and long-distance backpackers alike. Hailing from the Fast & Light series, the Z Lite ultra-light three-season camping mattress is perfect for those go-anywhere, sleep-on-anything treks and bivies where every ounce counts. The Z Lite is made using an all-new proprietary foam that's softer on top for extra comfort and denser on the bottom for added durability. As a result, it's substantial enough to keep you comfortable while mountaineering or on ski tours, yet packs smaller than any other closed-cell foam mattress thanks to its accordion-style design. Plus, the closed-cell foam is incredibly durable, providing an exceptional value and many years of worry-free performance. View specs in printer-friendly format

About Therm-a-Rest
In 1971, Seattle aerospace giant Boeing announced the largest layoff in company history, resulting in 50,000 people losing their jobs. Among the jobless were Jim Lea and Neil Anderson, both engineers who were eager to get back to work. Turning to friend John Burroughs--an avid mountain climber--for ideas, Burroughs suggested a better sleeping mattress, specifically one that was lightweight, warm, and comfortable.

Taking their inspiration from gardening cushions that expelled air as the gardener shifted his or her weight, the duo took a piece of open-cell foam and sandwiched it between two pieces of airtight fabric. Using an old sandwich maker, they melted the fabric onto the foam, creating a bond that was perfectly airtight. After adding a valve, their prototype was ready to test. Within two years, Lea and Anderson had partnered with Burroughs to begin production of Therm-a-Rest pads, the world's first self-inflating mattress. Under the name Cascade Designs, the private, family-owned company has grown into one of the most respected outdoor manufacturers in the world. Still based in Seattle, Cascade Designs sticks to the same fundamental principles it was founded upon: providing relevant and innovative products, exceptional quality, and service that exceeds your expectations.

I own both this and an inflatable Therm-a-Rest and have used other inflatable sleeping mats in the past. The Therm-a-Rest Z Lite is a bare-bones sleeping mat intended more for insulation from the ground than for comfort, at the lightest possible weight. As far as insulation goes, I felt it worked great - warmer, even, than an inflatable mat if only because your body doesn't have to heat any contained air so it has that "instantly warm" feel that foam tends to have. Comfort, though, is minimal. Its better than one of those thin blue mats but not as comfortable as an inflatable Therm-a-Rest - which, really, is a small margin. The foam is light but dense with little give - don't let the egg-carton texture fool you, it is not soft and squishy.

I use my Z Lite for backpacking, where extra weight matters. In this context the mat performed admirably. It was great that I didn't have to worry about puncturing it so I was able to sit and lay on it around the campfire while my friends with inflating mats had to do without. For fastidious folks, though, the "egg carton" divots are great at collecting bits of bark and dirt. I slept well, though stiffly, but was glad for the light weight when I had to carry it around. Lastly, many people have issues with the self-inflating Therm-a-Rests being slippery with nylon-type bags (which I agree with) - I had no such issue with the Z Lite since its not made of the same material.

Lets start at the begging, I purchased this sleeping pad with the sole purpose to replace my military issue THERM-A-REST air pad.

First thing I noticed when I pulled it out of the Amazon box was how light it was. The next thing was the bulk when folded up. Not really "bulk", but more like a big rectangle. This isn't a huge setback just something to consider.

I did a couple size comparisons with standard US military gear. This pad doesn't work very well with the GORE-TEX bivy, mainly because it is a little too long and also likes to fold back on itself when trying to enter the bag. Next I tried using it with a standard cot. The pad fit very well and comfortable.

The main reason I enjoy this pad is that it does not slide around like air pads do. Next I will list some observations that will help out any buyers.

First, I would recommend using a sheet or placing this under your bag. I have tried it without a sheet and found the feel of the foam against the skin is a little uncomfortable. If you are using this outside the wire or keeping your clothes on when you sleep than a sheet is not needed.

Second, there is no retention straps that come with this pad.

I would highly recommend this pad to anyone whether deployed or camping.

I had one of those foam rolls that you get from walmart for 5 bucks for years. I think it was once light yellow. For some reason I got rid of it. I've been fine sleeping on the ground for a long while, but I tend to do most of my camping in the warm months and in warm places.

But I wanted to do more and so I needed to be able to get out and sleep on the cold hard ground. Hard ground is fine, but I knew I couldn't sleep well on the cold ground. At least not with my summer weight bag. So I picked up the thermarest z-light. This is how you make a 40° bag work at 40°.

rolling the thing from walmart is about as painful as getting the air out of the self-inflating air pads. Maybe they're better now than they were 10 years back, but I always found those annoying. The accordion zig-zag of the Thermarest makes sure you get the pad down to packable size far more quickly than mr. cheapskate walmart and too much money inflatable thingy. It kinda springs out, but is fine once you get it lashed onto your pack.

Now. There are a lot of people below who complain that you can feel the ground through this pad. And that it's not soft. And that they can't sleep because they need a feather bed. bah. This thing was made for people who want to go sleep on the ground. If you need a feather bed, go get a room at a bed and breakfast. This works great.

4/5: it kept me warm while sleeping on a cold rock. It is very lightweight. It fold easily. BUT it's still less easily packed than a sleeping bag, and hangs over the edges. It's still the biggest thing in my pack. The edges do spring open until it's tied down.

Oh,and to the people whining about how hard it is, my wife is actually using this pad to help with her situps and crunches. The ground hurts her tailbone, so she sits on my nice cushy therm-a-rest. ;-)

Well, this is a very basic foam mat so there's little to be said about it. The mat serves its purpose well, it is very lightweight, it folds into a reasonably small brick and the amount of padding is about right (not too much, but enough). Manage your expectations; this is really just a foam pad - comfort is very limited, but for a minimalist backpacker this pad is the way to go. I like that there are no valves to fail and there's no skin to puncture - no matter what, reasonable padding will be provided.
