Trion R4
Main advantages
Used materials
Flat two-layer valve with check valve for easier inflation/deflation and pressure regulation in the mattress.
When the top layer of the valve is opened, the mattress can be easily inflated thanks to the non-return flap without losing pressure. By pushing the flap, the pressure in the mattress can be gently regulated. When the second layer is opened, the valve is fully open and the mattress can be easily deflated.
Detailed Description
Ultralight Gear Without Compromise
The Trion R4 is an inflatable sleeping pad designed for adventurers who want to minimize pack weight without sacrificing comfort or thermal performance. Thanks to its optimized construction, lightweight materials, and an R-value of 4, it offers an ideal balance of low weight, comfort, and year-round usability.
Year-Round Insulation with TRF Technology
Inside the sleeping pad, TRF (Thermo Reflective Foil) layers help reflect body heat back toward the user, reducing heat loss during the night. Combined with the integrated insulation layer, the pad achieves an R-value of 4, providing reliable protection from cold ground throughout the year.
Comfortable 9 cm Thickness
Despite its exceptionally low weight, the Trion R4 features a 9 cm thick air-cushioned construction. It effectively smooths out uneven terrain and separates the body from the ground, contributing to better sleep quality and improved recovery during multi-day adventures.
Mummy Shape for Weight Savings
The tapered mummy shape helps minimize both material usage and the amount of air required for inflation. The pad narrows to just 44 cm at its foot end, contributing to the exceptionally low weight of only 490 g without significantly compromising sleeping comfort.
Low Weight and Compact Packed Size
Weighing just 490 g, the Trion R4 ranks among the lightest insulated sleeping pads in its category. Packed down to only 10 × 25 cm, it leaves more room in your backpack or bikepacking bags for the rest of your gear.
Lightweight and Durable Materials
Both the top and bottom layers are made from 20D Nylon RipStop TPU. The RipStop structure helps prevent small tears or punctures from spreading, while the TPU lamination ensures airtightness and long-term durability. The result is an optimal combination of low weight, durability, and reliable performance.
Practical DLF Valve
The sleeping pad features a flat dual-layer DLF valve with a one-way check valve.
When the upper valve cap is opened, the pad can be inflated easily without air escaping back out. By gently pressing the check valve, the internal pressure can be adjusted continuously to achieve the desired level of firmness. Opening the second valve layer fully opens the valve, allowing the pad to be quickly deflated and packed away.
