WHY THE PRICE IS JUSTIFIED

Its price is primarily a warmth-to-weight achievement—R 4.5 at around 350 g—with 30D nylon, a sophisticated internal matrix and an easily adjusted WingLock valve. It is not the plushest or most durable here, but it is technically efficient.

MATERIALS

Shell30D rip HT nylon

A credible weight/durability balance rather than paper-thin UL fabric.

Internal structureTriangular Core Matrix

Suppresses convective air movement and supports the sleeper.

ReflectorThermaCapture radiant barrier

Returns radiant heat for R 4.5 insulation.

ValveWingLock one-way valve

Allows rapid inflation, dump deflation and fine adjustment.

IDEAL FOR

·thru-hiking
·fastpacking
·four-season weight-conscious travel
·users who carry every gram

NOT FOR

·rough car-camping ground
·sleepers needing a broad rectangular bed-like surface

DESIGN & ERGONOMICS

The horizontal baffles feel controlled rather than hammock-like; NXT’s quieter construction makes a material usability improvement. Choose Regular Wide if shoulder room is important.

LONGEVITY

Includes a pump sack, stuff sack and field repair kit. WingLock components are designed for straightforward service; still use a protective tent floor and keep the 30D shell away from grit and sharp debris.
