Self-Inflating Mat Nils Extreme 15-05-013 blue-grey — camping sleeping mat, compact roll-up

Self-Inflating Mat Nils Extreme 15-05-013 blue-grey is a portable camping sleeping mat designed to provide thermal insulation and cushioning for outdoor use. The mat uses an internal open-cell foam core that expands when the valve is opened, allowing the pad to self-inflate to a usable thickness. When deflated, the mat rolls up compactly and secures with straps for convenient transport in a backpack or vehicle. The blue-grey cover is durable and intended for contact with tents, ground surfaces and sleeping bags.

Advantages

The self-inflating construction reduces setup time and eliminates the need for external pumps while maintaining consistent cushioning across the surface. Lightweight and rollable design simplifies packing and saves space in luggage. The outer material and foam core combine to offer insulation from cold ground and impact protection for a more comfortable night outdoors. The included valve provides quick inflation and controlled deflation for repeatable use.

Suitable for

• Backpacking and hiking trips where compact weight and volume are priorities
• Car camping and weekend outdoor stays
• Festival and overnight event use where simple setup is needed
• Emergency or spare sleeping surface for guests or shelter kits

How to use

Place the mat on a reasonably flat and debris-free surface inside a tent or shelter. Open the valve to allow the foam core to expand and self-inflate; depending on ambient temperature and pressure, the process may take a few minutes. For firmer feel, add a few breaths through the valve and then close it. To pack, open the valve to release air, roll the mat tightly from the opposite end toward the valve and secure it with straps or ties. Store the mat dry and rolled for transport.

Usage recommendations

For best performance, use the mat on a clean groundsheet or tent floor and avoid sharp objects. If long-term storage is planned, keep the mat clean and dry and store it uncompressed or loosely rolled to preserve foam resilience.
