Vango’s most recent lightweight sleeping bag innovation, the Mantis 300, features their distinctive ThermX design. ThermX increases the warmth-to-weight ratio by concentrating warmth where it is needed through a combination of proprietary construction and insulation technology. This allows you to use a smaller, more compressible pack size without sacrificing performance. The durable Polair Eco ripstop fabric reduces weight while maintaining breathability and water resistance. Additionally, the updated Arrow Foot 2.0 design enhances comfort and flexibility at your feet, while Thermal Reverb and Thermal Embrace work to retain warmth.
