Flextail Zero Mattress R05 Regular L (orange)

The Flextail Zero Mattress R05 Regular L is a modern air mattress designed for discerning outdoor enthusiasts. It combines high thermal insulation (R-value 5.6), a comfortable thickness of up to 10 cm, a lightweight trekking design, and an advanced 7-layer insulation structure. Thanks to its durable 20D Ripstop Nylon fabric with a TPU coating, ergonomic U-shaped air chambers, and effective aluminum insulation, the mattress ensures a comfortable night’s sleep even in challenging terrain. The Regular model offers a full, rectangular sleeping surface, making it ideal for those who value maximum space and stability when sleeping in a tent, trekking, or camping year-round.

Insulation that protects against the cold – R-value 5.6

One of the mattress’s most important features is its high R-value of 5.6. This means highly effective protection against heat loss to the cold ground. In practice, the mattress ensures a comfortable night’s sleep at temperatures around -7°C, and its operating limit extends as low as -18°C. Thanks to this, the R05 Regular model is ideal not only for summer but also for spring, fall, and winter expeditions.

More Sleeping Space – The Comfortable Regular Shape

The Regular version offers the full width of the mattress along its entire length, which translates to greater freedom while sleeping. This feature will be especially appreciated by people who frequently change positions at night or simply like to have more space. When unfolded, the mattress measures approximately 196 × 65 × 7 cm, providing comfortable support for the entire body and stability even on uneven ground.

U-shaped air chambers – stability and even support

The mattress utilizes an innovative system of U-shaped air chambers that stabilize the body and evenly distribute pressure while you sleep. As a result, the mattress better conforms to the user’s body shape and reduces the feeling of sinking into one part of the surface. This design also improves stability when sleeping on your side and enhances sleep comfort throughout the night.

Up to 10 cm thick – insulation from a hard surface

The mattress reaches a maximum thickness of approximately 10 cm, which effectively isolates the body from a cold and uneven surface. In the central section, the construction is approximately 7 cm thick, maintaining an ideal balance between stability and resilience. This design makes even sleeping on rocky or hard ground significantly more comfortable.

Advanced 7-Layer Insulation Construction

The R05 model is designed with a multi-layer thermal insulation structure that effectively traps heat within the mattress. The construction features a durable layer of 20D Ripstop Nylon, a waterproof TPU coating, a special heat-reflective aluminum coating, and air-insulating layers. Together, these elements create a system that minimizes heat loss to the ground and ensures pleasant warmth even on cold nights.

Durable 20D Ripstop Nylon

The mattress is made of lightweight yet highly durable 20D Ripstop Nylon, designed for intensive outdoor use. The special Ripstop weave reduces the risk of tears and prevents damage from spreading. An additional TPU coating enhances the structure’s airtightness and protects the mattress from moisture and abrasion.

Easy Inflation and Quick Deflation

The mattress is equipped with a one-way TPU valve, which significantly simplifies use while camping. The valve’s design prevents air from escaping during inflation, making the process of preparing the mattress for sleep quick and convenient. After a night’s rest, the air can be deflated just as easily, allowing you to pack up your gear efficiently and hit the road again.

Proven reliability – 4S quality testing

Every Flextail mattress undergoes a rigorous 4S Testing Standard quality control process. This includes, among other things, a 48-hour pressure retention test, monitoring of changes in air volume, and temperature control inside the mattress. These procedures ensure that the mattress maintains its stability and airtightness even during prolonged use in demanding outdoor conditions.

Compact when packed—perfect for trekking

Despite its high level of comfort, the mattress remains very compact. When folded, it measures approximately Ø13 × 27.5 cm, so it fits easily into a trekking backpack or travel bag. Its light weight and small pack size make the Flextail Zero Mattress R05 Regular L an excellent choice for those who travel light but don’t want to sacrifice a comfortable night’s sleep in the great outdoors.
