Therm-a-Rest - NeoAir XTherm Vapor 2020

When your backcountry activities call for extreme insulation and an ultralight size, climbers and mountaineers turn to Thermarest's NeoAir XTherm. An uncompromising sleeping pad with an insulation value of 6.9 R-Value.

The unrivaled Triangular Core Matrix offers the best warmth to weight ratio of any air mattress construction. Construction gives the 2.5-inch (6.4 cm) thick pad superior stability, boasting the most inches of weld for the campo's maximum comfort.

The foldable pad boasts an R-value of 6.9, allowing users to take it to the most extreme conditions. Available in several sizes, including a spacious and regular one, the XTherm features the high-performance WingLock valve, which allows the pad to inflate three times faster thanks to a wider opening and one-way inflation.


• Unmatched warmth and weight: Patent-pending reflective ThermaCapture ™ technology traps radiant heat, while Triangular Core Matrix ™ construction minimizes convective heat loss, all without the hassle of volume, weight or durability of padding in down and synthetic.

• Excellent comfort: 2.5 inches (6.4 cm) thick and the baffled internal structure provide unrivaled stability and support.

• Ultra-Packable: The low-bulk materials make the mattress ultra-compact, as small as a bottle of water.

• WingLock ™ Valve: Our intuitive and reliable valve maximizes airflow for easier inflation and faster deflation. The wings activate for one-way inflation to save breath.

• Multiple Sizes: Offering a range of sizes, including a wide regular width, allows you to choose a length that best suits your adventure needs.

• Pump bag, containment bag and repair kit included

Probabilmente il miglior materassino sul mercato
Ho acquistato il primo materassino Thermarest NeoAir XTherm ancora 5 anni fa.
Il rapporto peso/compattezza/isolamento è incredibile. Lo ho usato circa 2-3 volte al mese per 5 anni e non ho mai avuto problemi di freddo anche dormendoci direttamente sulla neve o sulla roccia nuda.
Una volta gonfiato è davvero comodissimo, e avendolo confrontato con altri materassini simili di miei amici posso dire che è di gran lunga il più comodo.
Se vogliamo trovargli un difetto, va detto che se una persona tende a muoversi molto durante il sonno, è un po\' rumoroso.

Ora che la mia compagna ha deciso di cambiare il suo vecchio materassino, ho deciso di regalarle io questo.
La nuova versione ha una nuova valvola che rende il gonfiaggio decisamente più semplice e veloce.

Colgo l\'occasione per ringraziare Mountain Gear per le comunicazioni veloci e cortesi e per le spedizioni ineccepibili.
