Review: Great bag but doesn’t hold my helmet - Attached are some pictures. For scale, my helmet is a XL and my lunch box is one of the bigger ones you can get, an unusual size that’s bigger than most cloth lunchboxes. This advertises that a helmet can fit, but mine is a pretty common helmet (Scorpion line) and at XL it does not fit. Well, it fits but it won’t zip completely. The picture attached shows the helmet in and as far as I can zip which isn’t far at all. I’m sure a L would fit, but I can’t say for sure. On the flip side, my large lunch box does fit! Which is what I wanted this for, mostly, for those items that I want to carry with me while I’m actively riding. The helmet not fitting is not that big of a deal because I usually take my helmet with me wherever I go. Which brings me to my next point… This is not very well secured to prevent theft. You can get put a small, TSA baggage sized lock on the zippers, but all a thief needs to do is unbuckle the pack from the attached straps and walk off with the whole bag and then destroy the lock in a secure place. There is NO way to secure those straps. The straps do make it so someone can’t just up and take the bag off your bike in one go and it also does keep it secured while riding. I’ve put about 100 miles on my bike with this thing on and it hasn’t come off yet. It’s still snug in there. Max speed I’ve gone with this on is 80 MPH to further give you an idea of how well it stays attached without falling off. It is universal so likely will fit your bike. This is attached to my 2022 Kawasaki Ninja 650 and it fits well under the rear latching compartment. It does take up my backseat, so no riders will be able to sit back there while this is on. But the pack does come with backpack straps, so you could either wear the pack or strap it to your passenger. I see the waterproof cloth and it seems to be made of decent quality. It has rubber elastics all around so it should fit very snug under the bag to keep it in place in case of rain. It has made it slightly more difficult to get onto my bike as I would usually have to glide my leg over my back seat and that’s a little more difficult with this on and will be even more challenging with something like my lunchbox in it. But it’s not impossible to get on even by yourself without help. All in all, it’s great and I like it. I like that it has reflectors on it which will also help keep me more noticeable in darker environments too. They’re not extremely noticeable, but it adds to what I already had just a tad without being too much. Review: Awesome 👌 👏 - Looks good on my naked bike, it is very roomy inside and is expandable! I was able to fit lost of stuff and it turns into a backpack!

And, from the looks of an AKT TT 200ds, the bags might sit too close to the tail pipes. You'd be better off with the "top of seat" bag by the same company. **Q: Missing cargo net. Have not heard back from the seller about the issue?** A: Call Amazon. They allow the shipper to list so they are responsible. U paid Amazon not the shipper. And don’t let them tell u otherwise **Q: Is there a warranty? the zipper broke literally the first time i used it.** A: Only if you purchase product insurance ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great bag but doesn’t hold my helmet *by N***N on September 19, 2022* Attached are some pictures.

I was able to fit lost of stuff and it turns into a backpack! Can't be it for this price! ### ⭐⭐⭐⭐ Simple but it works well on my bike for a standard pillion bag. *by A***R on October 14, 2022* The bag is bigger than I thought, and it expands easily, so it has very good capacity. The material seems sturdy and it has not broken so far, having survived a road trip of more than 2000 miles (with lots of rain). It fits well on the pillion seat of my bike, easy to fit (with straps running under the bike seat). I didn't try to fit it on the fuel tank though. The bag comes with two shoulder straps (a bit flimsy but adequate for short periods of time), a net, and a rain cover. That said, I rode on the rain for a few hours without the rain cover and while the bag was soaked itself, the contents remained dry. Two minor considerations (the reason why the product is not a 5 star): first, I would rather a waterproof product without the need for the rain cover (even though the product did well in the rain). Second, while the bag always remained securely tied to the seat, it moved back a little bit partially blocking the break light. It means that you have to regularly check its position in a long ride. Overall happy witht he purchase and would buy again. ## Frequently Bought Together - MIHUNTER Motorcycle Tail Bag,Seat Bag,Dual Use Motorcycle Waterproof Helmet Bag for Motorbike - with One Extra Motorcycle Cargo Net - JOYROOM Motorcycle Phone Mount, [1s Auto Lock][100mph Military Anti-Shake] Bike Phone Holder for Bicycle, [10s Quick Install] Handlebar Phone Mount, Compatible with iPhone, Samsung, All Cell Phone - ILM Motorcycle Balaclava Face Mask for Ski Model FM01 --- ## 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/286778707-motorcycle-tail-bag-waterproof-seat-bag-dual-use-backpack-cargo](https://www.desertcart.jp/products/286778707-motorcycle-tail-bag-waterproof-seat-bag-dual-use-backpack-cargo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-16*
