The Vango Mantis 400 is a high-performance lightweight sleeping bag designed for hiking, camping, and multi-day expeditions. Built with advanced ThermX technology, it focuses insulation where it’s needed most, delivering an improved warmth-to-weight ratio without adding bulk. This efficient design allows the sleeping bag to pack down smaller while still providing reliable warmth in cooler conditions. Ideal for longer routes like the West Highland Way or Duke of Edinburgh Award expeditions, it offers a balance of performance, comfort, and packability. Constructed with durable Polair Eco ripstop fabric, the Mantis 400 remains lightweight while offering breathability and water resistance. Additional features such as Thermal Reverb and Thermal Embrace help retain body heat, while the updated Arrow Foot 2.0 design improves comfort and flexibility around the feet.
