Product Overview

The Vango Mantis 300 Sleeping Bag is designed for users who require lightweight warmth, packability and dependable 3 season performance across camping, trekking and expedition environments. Featuring Vango’s advanced ThermX insulation system, the bag focuses warmth where it is needed most to improve thermal efficiency without unnecessary bulk.

Its lightweight recycled 40 denier ripstop nylon shell fabric balances durability, breathability and water resistance, while the soft-touch lining fabric remains highly compressible for reduced pack size. Thermal Reverb technology uses strategically placed aluminised layers to reflect body heat back towards the user, increasing warmth retention during colder nights.

The Thermal Embrace system uses elasticated lining threads to gently contour the sleeping bag around the body, reducing cold air gaps while still allowing natural movement during sleep. Combined with Omega ergonomic shaping around the head and shoulders, this helps maximise thermal efficiency throughout the bag.

A redesigned Arrow Foot 2.0 ergonomic footbox improves comfort and flexibility at the feet while minimising heat loss. Additional cold-weather performance comes from the insulated shoulder baffle, insulated zip baffle and shaped 3D hood.

The full-length two-way auto-lock zip allows easy ventilation adjustment from inside the bag, while anti-catch piping helps prevent snagging during use. An internal storage pocket provides convenient access to smaller essentials overnight.

Certified to ISO 23537-1:2022 temperature testing standards and supplied with a lightweight 3-strap compression stuff sack, the Vango Mantis 300 delivers excellent warmth-to-weight performance for a wide range of outdoor adventures.
