Self-Inflating Sleeping Mat Nils Extreme NC4018 — Marine color, self-inflating camping mattress

The Nils Extreme NC4018 self-inflating sleeping mat in Marine color is a compact camping mattress designed to provide insulated cushioning and quick setup for outdoor overnight use. Its foam-core self-inflating design allows the mat to expand and trap air for a stable sleeping surface, while the durable outer fabric adds abrasion resistance and ground insulation. The mat rolls up into a compact bundle with straps for transport and storage, offering a balance of comfort, thermal protection and portability for hikers and campers.

Advantages

The self-inflating foam core reduces setup time and ensures an even surface without manual inflation. A robust outer material resists tears and abrasions from rough ground and helps retain warmth. The compact roll-up design with fastening straps and lightweight construction simplifies carrying and packing in a backpack. The Marine color hides dirt and wear during repeated outdoor use.

Suitable for

• Backpacking and multi-day hikes where quick camp setup is needed
• Car camping and weekend trips for added sleeping comfort
• Outdoor events, festival camping and emergency overnight use
• Campsites with uneven or cold ground requiring insulation

Key specifications

• Self-inflating foam core for automatic air intake and cushioning
• Durable outer fabric providing abrasion resistance and ground protection
• Compact roll-up storage with fastening straps for transport
• Lightweight design aimed at easy carrying in a backpack
• Thermal insulation suitable for outdoor overnight temperatures

How to use

Unroll the mat on a clean, flat area and open the valve to allow the foam core to self-inflate. Wait until the mat reaches the desired firmness; if a firmer surface is preferred, add a few manual breaths through the valve and then close it. Close the valve before rolling the mat for storage. To pack, open the valve briefly while rolling from the opposite end to expel air, secure with the straps, and stow in a backpack or vehicle.

Usage recommendations

Use a groundsheet or tent footprint to protect the mat from sharp objects and extend its service life. Regularly inspect the surface for punctures and keep the valve free of debris. Store the mat uncompressed when possible to preserve foam resilience and check inflation before each trip.
