Can I use this mattress in mild weather?
While it is designed for extreme cold, it can be used in milder weather. However, it may be warmer than necessary, and lighter options might be more suitable for summer camping.
How should I clean the mattress?

What is the warranty period for this mattress?
Please refer to the product packaging or the manufacturer's website for specific warranty information, as it can vary by region and retailer.

Troubleshooting
Mattress is not inflating fully
Ensure the valve is fully open and screwed in correctly. Check for any obstructions in the inflation port. Use the provided pump sack for optimal inflation, avoiding lung moisture.
Deflates overnight
Inspect the mattress for small leaks by listening closely or submerging in water (if possible and dry). Check the valve seal for tightness and damage. Ensure no sharp objects are near the mattress.
Reduced warmth over time
The down may have lost loft due to compression or moisture. Air the mattress out in a dry environment, and if necessary, use a low-heat tumble dryer with tennis balls to restore loft.
User sliding off the mattress
Ensure the mattress is laid on a flat surface. Utilize the XXL outer compartments by positioning yourself centrally. Check if the mattress is fully inflated, as a firmer mattress can sometimes offer more stability.

Setup, Compatibility & Care
Setup:
- Unpack the mattress and allow it to naturally inflate for a few minutes. The down fill may require some lofting.
- Use the included inflation sack or pump to fully inflate the mattress to your desired firmness. Avoid using your mouth to inflate, as this can introduce moisture into the down.
- Close the valve securely.
Compatibility:
- The mattress is designed for use in tents, shelters, or bivouacs.
- Compatible with standard sleeping bags.
- Its robust design makes it suitable for a variety of ground surfaces, though using a ground sheet is always recommended for added protection.
Care:
- Cleaning: Wipe the mattress with a damp cloth. Avoid harsh detergents or soaking the mattress.
- Drying: If the mattress becomes damp, allow it to air dry completely away from direct heat or sunlight. Ensure it is fully dry before storing to prevent mildew and protect the down.
- Storage: Store the mattress loosely in its stuff sack or hang it in a dry, well-ventilated place. Avoid long-term storage compressed, as this can degrade the down's loft.
- Down Maintenance: Periodically air out the mattress to refresh the down's loft. For deep cleaning or to restore loft, consider using a down-specific cleaner and a tumble dryer on a low heat setting with tennis balls.
