FAQs

What is the comfort temperature for this bag?

The comfort temperature rating for the MT500 is 15°C.

Can I use this in winter?

No, this bag is designed for warm-weather use. The limit temperature is 10°C, so it should not be used in cold or freezing conditions.

How much does the bag weigh?

The sleeping bag weighs approximately 660g.

Is the bag waterproof?

It features a water-repellent surface treatment to protect against light moisture, but it is not fully waterproof.

Can I connect two of these bags together?

Yes, this model is designed to be twinnable with other compatible MT500 bags.

What is the packed size?

The bag compresses down to a compact 4.2L volume.

Troubleshooting

Zipper keeps getting stuck on fabric

Hold the inner draft tube away from the zipper track while sliding the zipper slider.

Bag feels less 'fluffy' after long storage

Shake the sleeping bag vigorously and let it air out in a warm, dry room for a few hours to allow the insulation to expand.

Water penetrating the outer shell during heavy rain

The bag has a water-repellent treatment, not a waterproof rating; ensure you use a waterproof pack liner or cover to protect the bag from external elements.

Pros and Cons

Pros

  • Extremely lightweight at 660g
  • Highly packable for minimalist packing
  • Water-repellent fabric coating
  • Adjustable hood for better thermal regulation
  • Can be paired with another bag for two-person use

Cons

  • Not suitable for temperatures below 10°C
  • Mummy shape can feel restrictive for those who prefer more legroom
  • Limited insulation is not ideal for high-altitude trekking

Setup, Compatibility & Care

To maximize the lifespan of your sleeping bag, store it unfolded in a dry place when at home to maintain the loft of the fill. When in the field, use the included compression bag to minimize the packed size inside your backpack. For cleaning, use a front-loading washing machine on a gentle cycle with a technical gear detergent, and ensure it is thoroughly air-dried before storing. To connect two bags, simply align the zippers of two compatible MT500 models and pull them together. Always inspect the zippers before use to ensure no fabric is caught, which helps maintain the structural integrity of the closure.
