Vango Mantis 400 4 Season Sleeping Bag

Why Choose the Vango Mantis 400 Sleeping Bag?

The Vango Mantis 400 Sleeping Bag is a lightweight yet high-performance 4 season mummy sleeping bag engineered for cold UK camping, winter trekking and demanding expedition use. Designed around Vango’s advanced ThermX construction, it targets insulation where it is needed most, delivering exceptional warmth-to-weight performance without unnecessary bulk.

At just 1.44kg, the Mantis 400 stands out as a genuinely lightweight winter-ready sleeping bag, making it ideal for rucksack based adventures, higher elevation camps and Duke of Edinburgh Award expeditions in colder conditions. If you need reliable insulation for sub-zero nights but still want a compact pack size, this model offers an impressive balance of warmth and compressibility.

The recycled 40 denier ripstop nylon shell keeps overall weight down while remaining breathable and water resistant in changeable weather. Inside, Thermal Reverb aluminised fabric layers reflect body heat back towards you to improve heat retention, while Thermal Embrace elasticated lining reduces cold spots by gently drawing the bag closer to your body without restricting natural movement.

Engineered with Omega shaping, the head and shoulder area is ergonomically tailored for thermal efficiency, with seams and zips positioned lower in the bag to retain warmth more effectively. The insulated adjustable shoulder baffle, 2 panel 3D hood and insulated zip baffle help seal in warmth on freezing nights. The redesigned ergonomic footbox increases comfort while helping to minimise heat loss from the lower section of the bag.

Certified to ISO 23537-1:2022 temperature standards, with a limit rating of -6°C and an extreme rating of -20°C, the Mantis 400 is built for genuine cold-weather performance. Supplied with a 3 strap compression stuffsack and backed by a 2 year warranty, extendable to 3 years when registered, it offers dependable, lightweight winter protection for serious outdoor use.
