The Mantis 400 is our latest lightweight sleeping bag, featuring the innovative ThermX design. This cutting-edge technology combines proprietary construction and insulation methods to optimize warmth where it's most needed, enhancing the warmth-to-weight ratio. This means a smaller, more compressible pack size without sacrificing performance when it's needed most.

Crafted from durable Polair Eco ripstop fabric, the Mantis 400 remains breathable and water-resistant, all while reducing weight. Thermal Reverb and Thermal Embrace technologies work together to retain heat, while the updated Arrow Foot 2.0 design provides additional comfort and flexibility for your feet.

Key Features:

  • Recycled 40D Ripstop Nylon Shell – Durable, lightweight, water-resistant, and highly breathable for reliable performance in any condition.
  • Recycled 40D Ripstop Nylon Lining – Soft-touch, tear-resistant, and highly compressible to minimize pack size without compromising comfort.
  • ThermX Design – A unique construction and insulation system that directs heat to where you need it most for an enhanced warmth-to-weight ratio.
  • Thermal Reverb – Aluminized fabric layers are strategically placed to reflect heat back, improving warmth and heat retention.
  • Thermal Embrace – Elasticated threads in the lining gently cinch the bag closer to your body, reducing cold spots while maintaining freedom of movement.
  • Insulated Adjustable Shoulder Baffle – Designed to retain heat within the bag, ensuring consistent warmth throughout.
  • 2-Panel 3D Hood – Specifically shaped to prevent heat loss from the head, providing maximum warmth and comfort.
  • Full-Length Two-Way Auto-Lock Zip with Zip Guard – Offers adjustable ventilation or full warmth and can be easily operated from inside the bag, with anti-catch piping to prevent snags.
  • Omega Shaping – Ergonomically tailored around the head and shoulders to enhance heat retention, with zips and seams placed strategically in the lower part of the bag to preserve warmth more effectively.
  • Insulated Zip Baffle – Reduces cold spots and retains heat along the zipper.
  • Internal Pocket – Convenient storage for small items within easy reach.
  • Ergonomic Footbox – Redesigned for enhanced comfort and to minimize heat loss, providing a better foot fit.
  • 3-Strap Compression Stuffsack – Reduces overall pack weight and increases compressibility for easy transport.
  • Independently Tested Temperature Ratings – Tested to EN 23537-1:2022 standards, giving you confidence in its accuracy and performance.
