Therm-a-Rest Z Lite Original

The Z Lite is significantly more durable because it is made of closed-cell foam, meaning it cannot puncture or leak air. While it lacks the plush, thick cushioning of an inflatable pad, it offers a reliable, consistent barrier that is much faster to set up and pack away.

The Z Lite has an R-value of 2.0, which is generally suitable for three-season use. For winter camping, many hikers use it as a base layer underneath an inflatable pad to add extra insulation and protection from the frozen ground.

Because of its accordion-style folding design, the Z Lite folds down into a compact rectangle rather than rolling up. Most backpackers strap it to the outside of their pack using compression straps or tuck it vertically inside the pack against the back panel to provide structure.

At 0.75 inches thick, the Z Lite is firmer than air-filled pads. Side sleepers may find it less forgiving on the hips and shoulders, though many use it in combination with a sleeping bag or a second pad to improve comfort.

No, the closed-cell foam construction is non-absorbent. If it gets wet, you can simply shake it off or wipe it down, and it will dry almost instantly.
