Nemo Tensor AllSeason vs. Extreme: Weight, R-Value, and Performance
The Nemo Tensor AllSeason and Extreme mattresses represent significant advancements in lightweight backpacking comfort. The AllSeason boasts a 5.4 R-value, impressive for its weight of approximately 19 oz (535g). The Extreme model takes it a step further with an astounding 8.5 R-value, though at a slightly heavier 25 oz (722g). Both mattresses are 25 inches wide and 72 inches long.
Despite the impressive R-values, user experiences have been mixed. While many praise their warmth, some report encountering cold spots, particularly with the Extreme model. This could be due to the internal film layers sticking together, creating uneven insulation, or simply body weight distribution.
The weight-to-warmth ratio of both mattresses is remarkable, making them strong contenders for cold-weather backpacking. However, the possibility of cold spots is a crucial consideration when choosing between the two models.
Comparison with Other Lightweight Mattresses
The Nemo Tensor mattresses are not alone in the lightweight, high-R-value market. Competitors like the Sea to Summit Etherlite XT Extreme (6.2 R-value) and Zenbivy Light Mattress (R5) offer similar warmth, but with different size and weight profiles. The Sea to Summit option is noticeably bulkier, while the Zenbivy is more compact and comfortable for some users.
Zenbivy also offers a new ultralight option, further demonstrating the evolution in the lightweight mattress market. The Big Agnes Red SL (under R5) represents a more traditional option, prioritizing comfort over minimal weight. Choosing between these depends heavily on your priorities: extreme warmth vs. packability and comfort.
Ultimately, finding the right mattress comes down to balancing warmth, packability, comfort, and cost. While all these options are relatively expensive, their impact on sleep quality during backpacking trips can be substantial.
Repairing a Nemo Tensor Mattress
A crucial aspect of any backpacking gear review is durability. During testing, a slow leak developed in the Nemo Tensor AllSeason mattress. The leak wasn't a puncture from a sharp object; it appeared spontaneously. While unexpected, the included patch kit offered a solution, though it proved somewhat challenging to use.
The Nemo patch kit included adhesive patches and thin fabric, but the adhesive reacted poorly with the seam sealer, making application difficult. An alternative, third-party repair kit (Gear Aid) with larger patches and seam sealer yielded better results.
The ability to easily repair a damaged mattress is vital for multi-day trips. Choosing a mattress with a reliable repair system, or carrying a comprehensive repair kit, is highly recommended.
Conclusion: Which Mattress is Right for You?
The Nemo Tensor series offers excellent warmth-to-weight ratios, especially the Extreme model. However, potential cold spots are a factor to consider. Other options, like the Zenbivy Light and Big Agnes Red SL, offer various levels of warmth and comfort, with trade-offs in weight and bulk.
The best choice depends on your backpacking style and priorities. If prioritizing warmth in cold conditions is paramount, the Nemo Tensor Extreme is a strong contender, despite the cold spot risk. If minimizing weight and bulk is key, the Zenbivy Light or Big Agnes Red SL might be more suitable.
Ultimately, investing in a high-quality air mattress greatly enhances backpacking comfort and sleep quality. Carefully weigh the pros and cons of each mattress to find the perfect fit for your needs.
