Product Information

Full details

The Vango Mantis 300 is a lightweight, 3-season mummy sleeping bag for campers prioritizing warmth-to-weight ratio. Its key benefit is effective heat retention through advanced ThermX technology and a compact pack size. A potential caveat is its -1°C limit, which may be insufficient for very cold conditions.

FAQs

What is the intended temperature range for the Mantis 300?

The Mantis 300 has an independently tested temperature rating of Comfort 3°C, Limit -1°C, and Extreme -12°C. It is best suited for 2-3 season use, from late spring to early autumn.

How do I clean the Mantis 300?

It is recommended to hand wash the sleeping bag using a cool, mild detergent. Rinse thoroughly and allow it to air dry completely. Avoid machine washing or tumble drying.

Can this sleeping bag be used in winter?

While the extreme rating is -12°C, the comfort rating is 3°C and the limit is -1°C. For consistently cold winter conditions, a bag with a lower comfort rating and more robust insulation would be more appropriate.

What does 'ThermX Design' mean?

ThermX is Vango's proprietary technology that combines a specific construction and insulation system. It's designed to direct warmth efficiently to where your body needs it most, improving the warmth-to-weight ratio and allowing for a more compact pack size.

How does the Arrow Foot 2.0 improve comfort?

The Arrow Foot 2.0 is an updated ergonomic design for the footbox of the sleeping bag. It provides increased space and flexibility around your feet, allowing for more natural movement and reducing the feeling of constriction.

What is the pack size of the Mantis 300?

The packed size is approximately 27cm in length and 19cm in diameter. This is achieved through the use of lightweight materials and a compression stuffsack.

Is the Mantis 300 made from recycled materials?

Yes, the Mantis 300 features a recycled 40D ripstop nylon shell and lining, as well as 4T Eco - Recycled Synthetic Filling. It is part of Vango's Earth Collection.

Troubleshooting

Zipper snags on fabric

Gently pull the fabric away from the zipper teeth. Ensure the anti-catch piping is correctly aligned. Lubricate the zipper with a silicone-based product if it continues to stick.

Sleeping bag feels cold

Ensure the hood and shoulder baffle are properly adjusted to seal out drafts. Check that the zipper is fully closed. Allow the bag to loft fully before entering. Ensure you are wearing appropriate base layers inside the bag.

Reduced loft or warmth over time

The synthetic insulation may have become compressed. Wash and air dry the sleeping bag according to care instructions to help restore loft. Avoid long-term storage in the compression sack.

Bag is damp after use

This is normal due to condensation. Ensure the bag is thoroughly dried before storing. Use the ventilation options on the zip during the night if conditions allow to reduce internal moisture.

Pros and Cons

Pros

  • Excellent warmth-to-weight ratio due to ThermX technology.
  • Compact and highly compressible for easy transport.
  • Durable and water-resistant Polair Eco ripstop fabric.
  • Enhanced comfort features like the Arrow Foot 2.0 and Thermal Embrace.
  • Reliable temperature ratings backed by independent testing.

Cons

  • The -1°C limit rating may not be suitable for extreme cold or winter camping.
  • Mummy shape can feel restrictive for some users who prefer more space.
  • Synthetic insulation can be bulkier than high-end down when uncompressed.

Setup, Compatibility & Care

Setup: Unpack the sleeping bag from its compression sack. Fully extend the bag and allow it to loft for at least 30 minutes before use to maximize insulation. For optimal warmth, ensure the hood is adjusted around your head and the shoulder baffle is in place.

Compatibility: The Vango Mantis 300 is designed for use with standard sleeping mats. Its mummy shape is intended to fit users up to 190cm tall. The left-sided zipper is compatible with most sleeping mat straps. Ensure the bag is not over-compressed for extended periods to preserve insulation loft.

Care:

  • Cleaning: Hand wash using a cool, mild detergent. Rinse thoroughly and do not wring. Machine washing is not recommended.
  • Drying: Air dry completely in a well-ventilated area, away from direct sunlight or heat. Never tumble dry. Ensure the bag is bone dry before storing.
  • Storage: Store loosely in a large, breathable cotton bag or mesh sack, not in its compression sack. This helps maintain the loft and lifespan of the synthetic insulation.
