I have washed it 4 times but it's still to strong of an odor to try and sleep with. I'll be putting it in my 3 season porch for a few months I guess and see if it will eventually finish off gassing. Other than that I think it works as intended. **Q: Are there two airbags included?** A: No, just one airbag. It is extremely strong and sturdy with very thick gauge plastic. Seems very durable, unlikely to break or tear if left zipped inside. Air stays inside with great seal on the inflation opening. do not know the maximum weight it could bear. I am 145 lbs. The company selling was EXTREMELY helpful and responsive to me , and is directly in touch with their manufacturer. If for some reason you would need 2, you should message them to ask. **Q: Can I just order the backpack?** A: yes, order and try the fit, a slim line fit belt will help tremendously! Hint: secure below the air bag device. **Q: My backpack has a slow leak now after forgetting to deflate it for travel in a tight suitcase. Can I buy a replacement balloon for it?** A: Yes, but you need to send a request to the manufacturer for the replacement balloon. ## Frequently Bought Together - WoodyKnows Side-Sleeping Backpack Replacement Supporting Airbag, Used in Combination with Side-Sleeping Backpack Back Pillow (L) - Airmax Nasal Dilator Trial Pack | Anti Snore Device | 76% More Air for Better Breathing & Snoring Relief | Guaranteed Fit (1x Small & 1x Medium) - PHCOMRICH Anti Snoring Device Silicone Tongue Retaining Stop Snoring Solution Premium Tongue Retainer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/197540600-replacement-airbag-filling-accessory-of-woodyknows-side-sleeping-backpack-large](https://www.desertcart.jp/products/197540600-replacement-airbag-filling-accessory-of-woodyknows-side-sleeping-backpack-large) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-14*
