Ventra R3,5
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
Comfort and Insulation for 3-Season Adventures
The Ventra R 3.5 is an inflatable sleeping pad designed for users seeking the ideal balance of low weight, thermal comfort, and compact packed dimensions. With an R-value of 3.5, it provides reliable protection from cold ground during most outdoor activities from spring through autumn without significantly increasing pack weight or bulk.
SCC Technology for Low Weight
The SCC (Single Chamber Construction) design uses a single air chamber to achieve low weight and excellent packability. This simple and efficient construction provides an optimal balance of comfort, packed size, and overall weight, making the Ventra R 3.5 an ideal companion for multi-day adventures and lightweight travel.
Thermal 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 3.5, making it an excellent choice for 3-season use.
Comfortable 7 cm Thickness
The 7 cm thick air-cushioned construction helps smooth out uneven terrain and separates the body from the cold ground. The result is a more comfortable night's sleep and better recovery after a demanding day outdoors.
Low Weight and Compact Packed Size
Weighing just 610 g and packing down to only 10 × 26 cm, the Ventra R 3.5 fits easily into a backpack or bikepacking bags without taking up unnecessary space.
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.
Durable Materials
Both the top and bottom layers are made from 40D 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 in demanding outdoor conditions.
