Unboxing and Initial Impressions
Both the Nemo Tensor and Sea to Summit Ether Light XT sleeping pads arrive with a comprehensive package: a pump sack, a storage sack, and a patch kit. The storage sacks are practically identical. The Tensor's compact size is impressive, roughly the same size as a 32-ounce water bottle; the Ether Light is slightly larger.
Each pad easily fits back into its stuff sack after inflation, a welcome feature often lacking in other pads. Both pads stick out slightly at the top, but repacking is a breeze.
Inflation and Valve Systems
The Nemo Tensor boasts a unique band to keep it compact and ultralight, potentially eliminating the need for the stuff sack. Its inflation uses a two-part valve system, requiring a six-inch distance for optimal airflow. The valve lies flat, preventing discomfort during sleep.
The Sea to Summit Ether Light XT utilizes a similar two-part valve system and also benefits from a vortex-type inflation technique, improving efficiency. Both systems offer a satisfying ‘click’ when correctly engaged, guaranteeing proper inflation.
R-Value and Warmth
Both pads offer similar R-values, indicating comparable warmth. The Nemo Tensor boasts an R-value of 3.5, while the Sea to Summit Ether Light XT has an R-value of 3.2. An R-value measures insulation; higher numbers signify better warmth.
These pads are ideal for three-season camping (spring to early fall), though colder sleepers might benefit from an additional insulating layer underneath. The small difference in R-value means both offer comparable warmth for mild conditions.
Materials and Durability
The Nemo Tensor uses 20D nylon, while the Ether Light XT employs 30D and 40D nylon, suggesting increased durability for the latter. Both pads are susceptible to punctures, emphasizing the need for careful handling and possibly using a footprint for added protection.
Though lightweight, these pads are premium and expensive. Protecting them with a footprint or tarp significantly extends their lifespan. While the thicker nylon of the Ether Light suggests better puncture resistance, both require careful use.
Size, Shape, and Comfort
Both pads are the same size (72 inches long x 20 inches wide), but the Ether Light's mummy shape tapers at the foot, providing a snugger fit in tapered tents. The Tensor's rectangular shape offers more overall space.
While both are comfortable, the Ether Light XT, with its four inches of thickness, offers a more luxurious, mattress-like feel, particularly for side sleepers. The Tensor, at three inches, is still exceptionally comfortable.
Deflation and Packability
Both pads deflate quickly and easily. The two-part valve systems allow for rapid air release, making packing simple. The included stuff sacks are well-designed and readily accommodate both pads.
While both are easy to pack, the Ether Light XT’s integrated pump sack eliminates the need for a separate item, which might be a slight advantage. However, this is only an issue for those focused on minimal weight.
Conclusion: Which Pad Reigns Supreme?
The Nemo Tensor and Sea to Summit Ether Light XT are both exceptional ultralight sleeping pads with minimal differences, each excelling in specific areas. The Tensor is lighter, slightly warmer (R-value 3.5 vs 3.2), and packs down slightly smaller.
The Ether Light XT boasts superior comfort, especially for side sleepers, thanks to its greater thickness (4 inches vs 3 inches) and mummy shape. The integrated pump sack is convenient, but adds a little extra weight. Ultimately, the best choice depends on individual priorities.
