Why Choose the Vango Mantis 300 Sleeping Bag?
The Vango Mantis 300 Sleeping Bag is a high-performance 3 season mummy sleeping bag designed for lightweight backpacking, UK campsite use and expedition adventures where warmth, weight and pack size all matter. Built around Vango’s innovative ThermX design, it strategically targets insulation where you need it most, delivering an improved warmth-to-weight ratio without unnecessary bulk.
Weighing just 1.34kg, the Mantis 300 strikes an excellent balance between lightweight performance and dependable 3 season warmth. It is ideal for spring, summer and autumn camping, including Duke of Edinburgh Award expeditions, rucksack based trekking and multi day hiking trips where space and weight are critical.
The durable Polair Eco recycled ripstop nylon shell reduces weight while remaining breathable and water resistant in changeable UK weather. Inside, Thermal Reverb aluminised layers reflect body heat back towards you to improve heat retention, while Thermal Embrace elasticated lining gently cinches the bag closer to your body to reduce cold spots without restricting natural movement.
Engineered with Omega shaping, the Mantis 300 is ergonomically tailored around the head and shoulders, with seams and zips positioned lower to retain warmth more effectively. The insulated ergonomic shoulder baffle, 2 panel 3D hood and insulated zip baffle work together to seal in warmth when temperatures drop towards freezing. A redesigned ergonomic footbox increases comfort and flexibility while helping minimise heat loss at the lower end of the bag.
Certified to ISO 23537-1:2022 standards, with a comfort rating of 3°C and a limit of -1°C, the Mantis 300 is well suited to cooler UK nights. Supplied with a 3 strap compression stuffsack and backed by a 2 year warranty, extendable to 3 years when registered, it delivers reliable, compressible performance for serious outdoor use.
