Product Overview

The Vango Mantis 400 is an advanced lightweight 4-season sleeping bag engineered for users who require dependable cold-weather performance without excessive pack weight. Featuring Vango’s innovative ThermX design, the sleeping bag combines targeted insulation placement and thermal efficiency technologies to maximise warmth while maintaining a compact and highly compressible packed size.

The durable Polair Eco ripstop shell fabric provides a lightweight balance of breathability, water resistance and durability, while the soft-touch recycled lining improves comfort and compressibility for easier transport during trekking, backpacking and expedition use.

Thermal Reverb technology uses strategically positioned aluminised fabric layers to reflect heat back towards the user, improving thermal retention in lower temperatures. Thermal Embrace elasticated lining technology gently contours around the body to reduce internal air gaps and minimise cold spots without restricting movement during sleep.

An ergonomically shaped Omega mummy profile improves warmth retention around the head and shoulders, while the insulated shoulder baffle, 3D hood and redesigned ergonomic footbox further enhance thermal efficiency and overnight comfort. The full-length two-way auto-lock zip allows adjustable ventilation and easy access while helping prevent heat loss during colder conditions.

Designed for demanding outdoor environments, the Vango Mantis 400 is well suited to winter camping, trekking, expedition travel and cold-weather outdoor adventures where warmth, packability and performance are essential.
