The Contenders: A Quick Overview
This review pits two popular ultralight foam sleeping pads against each other: the Robens ZigZag Slumber and the Therm-a-Rest Z Lite Sol. Both offer a lightweight, durable option for backpacking and camping, but differ significantly in price and features.

The Therm-a-Rest Z Lite Sol is a well-established choice, known for its durability and consistent performance. However, its price point can be a deterrent for budget-conscious adventurers.

The Robens ZigZag Slumber, on the other hand, is a relative newcomer. It boasts a surprisingly low price, making it a very attractive option. This review will explore whether it can compete with the established reputation of the Therm-a-Rest.
Price and Value Comparison
The most striking difference between these two pads is the price. The Therm-a-Rest Z Lite Sol typically retails for around £50, a significant investment.

In contrast, the Robens ZigZag Slumber is available for a fraction of the cost, at approximately £16. This drastic price difference begs the question: is the Robens a worthy substitute?

The lower price of the Robens doesn't automatically mean it's inferior. This review will delve into the specifics to determine if the cost savings compromise performance.
Specs and Features Head-to-Head
Both pads offer a similar thickness (2cm), providing decent insulation and comfort. The Robens ZigZag Slumber boasts a slightly higher R-value (2.2 vs. 2.0 for the Therm-a-Rest), suggesting marginally better insulation.

However, the Therm-a-Rest Z Lite Sol is slightly longer and wider. The packed size is where the Robens shines, being considerably more compact, making it ideal for backpacking.

Weight is another key consideration: The Robens ZigZag Slumber (286g) is notably lighter than the Therm-a-Rest Z Lite Sol (410g). This makes a tangible difference during long hikes.
Comfort and Practicality
While neither pad offers the luxurious comfort of an inflatable option, both provide adequate cushioning for a night's sleep on the trail. The Robens features unique 'lugs' and indentations designed to trap warm air, potentially enhancing comfort.

The Robens ZigZag Slumber's simplicity is a significant advantage. There's no inflation or deflation required, saving time and effort. Its rugged construction makes it resistant to punctures and moisture.

The Therm-a-Rest's established durability is undeniable, but the Robens provides a practical alternative with its ease of use and compact size.
Conclusion: The Verdict
The Robens ZigZag Slumber offers exceptional value for its price point. While it might not match the Therm-a-Rest Z Lite Sol's longevity in every respect, its lower weight, compact packed size, and surprisingly good insulation make it a compelling choice.

For budget-conscious adventurers, the Robens is a strong contender, offering a significant cost saving without compromising too much on performance. The higher R-value is a plus for colder weather.

Ultimately, the 'best' pad depends on individual priorities. If budget is a major concern and lightweight packing is crucial, the Robens ZigZag Slumber deserves strong consideration. However, if absolute longevity is paramount, the Therm-a-Rest remains a reliable, albeit more expensive, option.
