I took off the straps and plastic clip-on's that come with the bag, and instead use bungee Cords with carabiner hooks. Works much better this way for me. Plus, I can place it on my back as a back pack when walking the trail. Hope this helped u. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Tail Bag *by G***C on May 31, 2026* Right size tail bag.

I would highly recommend. ### ⭐⭐⭐⭐ Not 100% waterproof, but still fine. *by C***K on June 5, 2026* EDIT: This bag is not 100% waterproof. Got caught in a torrential downpour last week and while the material that makes the top of the bag up is indeed waterproof, the seams for the expansion and the opening are NOT. Water still seeped in. You'll likely be fine in a sprinkle, but a steady rain or downpour will most likely lead to water seeping in through the seams. This is a great little bag for keeping my phone and water bottle in while on longer jaunts. The expansion is a bit cumbersome if you tucked the tails of the straps under the seat, but it’s nice to have a smidge more room. The fact that the buckles are set up like a harness (meaning they’re connected by a cross-strap) rather than being two separate things that I’d have to try and line up correctly (as was the case on my Nelson Rigg tail bag) is what originally sold me on this, and they’re coming in clutch. Just take your back seat off, attach the bag to the seat, then reinstall the seat. Easy-peasy. I saw the other reviews about people creating their own internal structure so the bag maintains its shape and tried it with and without it: I definitely like it more with the structure. I just used a piece of thicker oak tag to start, but plan on upgrading it to 1/16 or 1/8 thick plastic. Looks pretty sick without screaming “HEY IVE GOT A TAIL BAG” so that’s nice too. ## Frequently Bought Together - MOSISO Motorcycle Tail Bag Multifunctional Waterproof Polyester Storage Saddle Bag, 10L Outdoor Sports Motorbike Rear Seat Light Tank Handbag Tool Carry Pouch with Shoulder Strap, Black - ILM Motorcycle Balaclava Face Mask for Ski Model FM01 - KEMIMOTO Tactical Gloves for Men, Touchscreen Motorcycle Gloves with Hard Shell & Palm Padding for Sports Motorcycle Cycling Tactical Airsoft Paintball Hunting Hiking Camping Climbing --- ## 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/479649569-mosiso-motorcycle-tail-bag-waterproof-polyester-storage-saddle-bag-black](https://www.desertcart.jp/products/479649569-mosiso-motorcycle-tail-bag-waterproof-polyester-storage-saddle-bag-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-11*
