Robens

The Robens HeatCore 3.8R Large mat is engineered to deliver excellent comfort, insulation, and reliability for outdoor use. Designed for three-season performance, it provides high thermal efficiency thanks to its double foil insulation, offering an outstanding warmth-to-weight ratio that balances comfort with packability. Constructed from lightweight materials, the mat incorporates the Robens Peak Valve system, which enables fast and efficient inflation and deflation with one-way airflow technology. A higher number of smaller air chambers improves stability and support while keeping overall weight and bulk to a minimum. Practical and travel-friendly, the HeatCore 3.8R Large comes with both a lightweight pump sack and a carry bag for easy transport and setup. It is also PFAS-free, supporting a more environmentally conscious outdoor experience.
