Usage Method Steps
After removing from storage bag, fully shake open to allow filling to regain loft, improving thermal effect. Before use in cold environments, it is recommended to unfold 10-15 minutes in advance to allow filling to fully expand. Completely zipping up and adjusting the hood can maximize thermal effect. After use, it is recommended to air dry before storage, avoiding too long compression causing filling to lose elasticity. Store in a loose state for long-term storage, regularly ventilate to ensure ready for use at any time.

Maintenance Guide
Hang in a dry, ventilated place for 2-4 hours after use to ensure internal moisture completely dissipates. Stains can be locally wiped with a damp cloth, severe stains hand washed with neutral detergent, avoiding machine washing and direct sunlight. Recommended storage environment temperature between -5°C and 35°C, avoiding long-term compressed storage, regularly take out and shake to maintain filling loftiness, extending service life. Perform a performance check once per quarter to ensure normal thermal function.

Q: What is the temperature adaptation range of this efficient thermal sleeping bag?
A: Designed for use in 0-15°C, comfortable temperature 5-10°C. Can be used for short periods below 0°C, but additional warming equipment is recommended to ensure sufficient warming effect.

Q: What advantages does polyester fiber filling have compared to other fillings?
A: Polyester fiber filling is lightweight, quick-drying, and has good thermal properties, maintaining over 80% thermal effect even in humid environments, with better recovery than down filling, more suitable for repeated use in disaster areas.

Q: Will the sleeping bag's thermal performance weaken with number of uses?
A: Normally, after 30-40 uses, thermal performance will decline by about 10-15%. Regular airing and shaking can restore some loftiness, extending effective thermal performance. Check thermal effect after every 20 uses.

Q: How to determine if the sleeping bag's thermal performance is still effective?
A: A simple test can be conducted: use for 30 minutes in a 5°C environment, if internal temperature rises above 15°C, thermal performance is good; if temperature rise is not obvious, replacement or enhanced warming measures may be needed.

Q: What special considerations are there for using this sleeping bag in disaster areas?
A: Avoid direct contact with wet slippery ground, use moisture-proof pads to enhance bottom moisture isolation. Simple warm-up exercises before sleep can raise body temperature, fully cover the head with the hood to reduce heat loss.

Q: How to ensure consistent quality when purchasing in bulk?
A: Request samples to test actual thermal effect before purchase, checking filling density and stitch quality. For large batch orders, request batch sampling, ensuring at least 5% of products from each batch are inspected.

Q: Is this sleeping bag suitable for long-term storage as emergency supplies?
A: Very suitable, polyester fiber structure is stable, correct storage can maintain good performance for 3-5 years. Avoid long-term compression during storage, ventilate and check once every 6 months to ensure expected thermal effect during emergencies.

Q: How to enhance the sleeping bag's thermal effect in extremely cold environments?
A: Use the "multi-layer warming method": place a layer of thermal underwear or thin blanket inside the sleeping bag to increase base temperature; cover with emergency blankets outside to reflect body heat; use moisture-proof pads to isolate ground cold.
