Choosing the right sleeping pad for backpacking can significantly impact your comfort and sleep quality. This review compares two popular options from Therm-a-Rest: the ProLite and the Z Lite. Both pads offer excellent insulation and packability, but cater to different priorities. The ProLite, a self-inflating pad, prioritizes convenience but sacrifices some durability. Conversely, the Z Lite, a closed-cell foam pad, excels in durability and water resistance, though it requires manual inflation.This detailed comparison examines the pros and cons of each pad, considering factors such as weight, pack size, comfort, insulation (R-value), and price. We'll explore the unique characteristics of each model, helping you determine which best suits your needs and backpacking style. Whether you prioritize lightweight convenience or rugged durability, this review will guide you towards the perfect sleeping pad for your next adventure.

Therm-a-Rest ProLite: Self-Inflating Comfort
The Therm-a-Rest ProLite is a self-inflating sleeping pad measuring approximately 20 inches wide by 72 inches long (about 6 feet). Its curved design helps save weight, though I personally find it less comfortable. The pad features a gray-green bottom and an orange top.
It packs down surprisingly small—roughly 4 inches by 4 inches by 10 inches, about the size of a 40-ounce canteen. It weighs approximately one pound, even with the included elastic bungee.
Self-inflating pads like the ProLite utilize a foam core that expands upon unrolling, drawing in air due to its "memory effect." Many users misunderstand this process, leading to negative reviews when the pad doesn't instantly inflate.
Therm-a-Rest Z Lite: Closed-Cell Foam Durability
The Therm-a-Rest Z Lite is a closed-cell foam pad, offering puncture resistance and water resistance. This makes it ideal for use on uneven terrain without worrying about rocks, branches, or water absorption.
While bulkier than the ProLite, its durability is a major advantage. It straps easily to the outside of a backpack, saving internal space. Minor bumps and scrapes are easily dismissed as battle scars.
Measuring approximately 20 inches by 5.5 inches by 20 inches, the Z Lite has approximately 11 foam panels. Some ultralight backpackers cut panels to save weight, although I don't see a significant benefit.
Comfort vs. Insulation: Understanding Sleeping Pad Expectations
Many online reviews criticize sleeping pads for discomfort, especially for side sleepers. It's crucial to understand that these lightweight pads prioritize insulation and packability over luxurious comfort. They protect you from the cold ground, not replace your home mattress.
While thicker Therm-a-Rest models exist, they compromise on weight and packability. These pads offer sufficient insulation for backpacking but shouldn't be expected to offer the same sleep quality as a full-sized air mattress.
The principle is similar to a sleeping bag: the bottom layer compresses under your weight, reducing insulation compared to the top. Sleeping pads provide a crucial layer of insulation to compensate for this compression.
ProLite vs. Z Lite: A Detailed Comparison
The ProLite (R-value ~2.5) offers self-inflation for convenience, but its durability is a concern. The Z Lite (R-value ~2) excels in durability and water resistance, and its lack of memory effect is a benefit for ease of packing and unpacking.
Both pads are roughly the same thickness when inflated (1 inch for ProLite, ¾ inch for Z Lite). Layering them provides extra comfort and insulation (approximately R4-R5 combined).
Consider your priorities: If you value lightweight self-inflation and can tolerate potential punctures, the ProLite is an option. If durability and water resistance are paramount, the Z Lite is a better choice.
Final Verdict and Recommendations
Both the Therm-a-Rest ProLite and Z Lite offer excellent insulation and packability for backpacking, but their strengths lie in different areas. The ProLite prioritizes convenience through self-inflation but lacks the durability of the Z Lite. The Z Lite, on the other hand, excels in durability and weather resistance but requires manual inflation.
Neither pad is designed for supreme comfort. If comfort is a top priority, consider investing in a more expensive, thicker air mattress. Ultimately, the best choice depends on individual needs and priorities. For a balance of convenience and durability, layering both pads offers a compelling combination.
Both pads offer good value, especially when purchased on sale. The ProLite typically ranges from $90-$140, while the Z Lite costs around $40-$45. For increased insulation and durability, I recommend using both pads together for an enhanced camping experience.
