This review details a rigorous field test of the Nemo Tensor Extreme sleeping pad, an R-value 8.5 pad, in the extreme cold of a Canadian Rockies glacier. The goal was to determine if its advertised warmth-to-weight ratio held up against truly frigid temperatures and icy conditions. A controlled experiment compared the Tensor Extreme to a Therm-a-Rest NeoAir Uber (R-value 2) to isolate the impact of the Tensor Extreme's insulation. The test also involved a variety of other gear, providing a comprehensive look at performance in demanding environments.Beyond the sleeping pad, this review covers the Durston X-Mid Pro 2 Plus tent, tested under heavy load and challenging weather; the Nemo Moonlight Elite chair, highlighting its comfort and innovative dual-purpose carrying case; and the MSR Reactor stove system, renowned for its rapid snow melting and water boiling capabilities. We’ll explore the strengths and weaknesses of each piece of equipment, offering insights into their suitability for various outdoor adventures and highlighting key design features and performance characteristics.

Testing the Nemo Tensor Extreme on a Glacier
My goal was to rigorously test the Nemo Tensor Extreme sleeping pad, boasting an R-value of 8.5, in real-world glacial conditions. I wanted to see if its advertised warmth-to-weight ratio held true against the extreme cold and icy terrain. This involved more than just a simple overnight test; I planned a controlled experiment comparing it to another pad.

The testing location was crucial. I chose a spot on a glacier in the Canadian Rockies, ensuring exposure to the frigid temperatures. The setup would include anchoring my tent using screw stakes, directly into the ice, for maximum stability and exposure to the cold ground.

The comparative pad I used was the Therm-a-Rest NeoAir Uber. With an R-value of 2, it served as a control, helping determine whether the warmth was primarily due to the Tensor Extreme's insulation or simply the ambient air.

Durston X-Mid Pro 2 Plus Tent Performance
The Durston X-Mid Pro 2 Plus tent accompanied me on this adventure. I'd previously had some reservations about its ability to handle significant weight given its ultralight design. However, the full hip belt and carbon fiber stays proved to be very effective.
Despite carrying a substantial load (well over its advertised 40-pound capacity), the pack remained surprisingly comfortable. The trampoline back also provided significant ventilation in the hot weather, although not as effective as some higher-end options.
The tent itself held up exceptionally well in challenging weather conditions. I encountered rain and wind, yet the tent remained secure and stable, thanks to the ice stakes.
Nemo Moonlight Elite Chair: Comfort and Convenience
The Nemo Moonlight Elite chair provided a comfortable and convenient seating option during the trip. Its adjustable backrest was a welcome feature, allowing me to recline or sit upright depending on the situation. This adaptability is excellent for various activities.

The included carrying case doubles as a groundsheet, a handy touch that prevents sinking into soft ground. It's a thoughtful detail, especially for those who prefer a bit of extra ground protection.

While the price is currently unknown (expected Spring/Summer 2024 release), its lightweight design and added features make it a potentially compelling addition to any camping kit.
MSR Reactor Stove System: Efficient Snow Melting
The MSR Reactor stove system was a key component of this trip. Its high price is justified by its exceptional efficiency in melting snow and boiling water quickly. The innovative design incorporates radiative heating and efficient airflow to enhance this speed.

This makes it perfectly suited for high-altitude or cold-weather camping where quick water boiling is essential. While expensive, its performance is unmatched for its intended purpose.

The system's focus on a single function—rapid water heating—makes it a specialized tool for specific environments and trips. While not ideal for all camping situations, it's a top performer in its niche.
Overall Gear Review and Conclusions
The Nemo Tensor Extreme, while initially disappointing in its warmth performance on the glacier, still demonstrates promising features. The updated materials, baffling system, and valve design are significant improvements. Further testing is necessary to assess performance fully in various conditions.

The Durston X-Mid Pro 2 Plus tent performs exceptionally well in diverse conditions, including wind and rain. The increased space compared to the original Pro 2 is a considerable advantage, especially for couples or those needing ample space for gear.
The Nemo Moonlight Elite chair is a comfortable, lightweight option with versatile adjustability and the added groundsheet feature. The MSR Reactor stove stands out as a premium, highly efficient system for melting snow and boiling water rapidly, although its high cost limits its applicability to specific needs.
