Product Details

WENTYL WINGLOCK™ - 3x faster inflation
The WingLock™ valve is a modern element placed in the mattress that accelerates the inflation process. Its design is based on a one-way mechanism that allows free airflow under high pressure, eliminating the risk of air escaping. The user will appreciate the efficient preparation for sleep while camping, enjoying comfort and saving time in dynamic outdoor conditions.

R value 3.2 for thermal comfort
A mattress with a value of R 3.2 is a key element in ensuring thermal comfort during rest. Its multi-layer construction with insulation materials effectively retains body heat, minimising energy loss. The user can enjoy a stable temperature while sleeping, regardless of cooler external conditions.

Ergonomic shape with protrusions
The mattress is designed with an ergonomic shape featuring special nodules on its surface. These nodules adapt to the body's contours, evenly distributing pressure and reducing pressure points during sleep. In practice, this means that the user can enjoy undisturbed sleep and wake up without discomfort, even after a long camping trip.
