Grapelet Motorcycle Tail Bag Backpack Waterproof ABS Hard Shell Motorbike Luggage Bags Helmet Bags with Expandable Storage 24L-35L

Sleek, modern design. This tail bag won’t disappoint you, and the price is unbeatable. The zipper allows you to unfold it so that there is enough room for a full face helmet. When zipped, the top case is rigid and has the appearance of carbon fiber, which gives an elegant look. It comes with a set of stripes to attach it to the rear seat / pillion but it is mostly designed for sport motorcycles, so if you have a touring bike like I do, you may need to attach it to the sissy bar. What I liked the most is:- Design- Capacity: 24liters (expandable to 35liters fully extended)- It comes with stripes to carry the bag as a backpack and it also comes with stripes to attach to the motorcycle- It is not waterproof but it includes a cover that makes it water resistant (when used as 24L bag)- Multiple options to carry/attach to the bike (rear seat, sissy, rack)- Zippers allow to lock the bag with a padlock (included)

This bag I placed on my pillion of a Triumph Tiger 900. It secures under the seat with a strap harness that stays in place for easy removal of the bag from the harness and easy replacement. It has backpack straps that you can use after you take it off the seat. It expands quite large, enough for my helmet, and comes with a tiny lock (of course a thief could knife the case open easily). For an overnight trip it’s perfect size. I plan to use it as carry-on luggage for air travel too. It’s sturdy and the Shell is strong. I love it.

seems to work good. helps to secure my saddle bags much better. i would recommend this bag for a single modular helmet or shoulder pack. price was ok.

Got the Chinese craftsmanship we're used to- plastic parts somehow attached on over the peel away protective plastic. Get past that and the included straps allow it to flop around like a fish on land. Almost completely useless.However, if you use your own straps/bungee cords to hold it in place, it becomes much more useful, and it can hold quite a bit.

Bought this originally only to put my motorcycle cover in it. Discover that is can hold my helmet aswell. There is a zipper near the bottom of the bag, allowing it to extend and hold even more stuff. It fit my xl helmet without a problem, and just the right size. My bike is 2022 z650. Forgot to put cover on during a rainy day, and to my suprise nothing inside is wet. Illinois Rain is... like storm. 11/10 would buy again

Looks nice , seems well built holds more than I thought it would . Several compliments , all thought it was carbon fiber . Happy with purchase .

I like it very much. It suits the purpose for what I need. I recommended to anyone

Goes from super compact to huge with just a zip. Really good design. Only reason it's not the full 5 stars is cause I think a bag that's $90 should last longer than a year and a few months. The main zipper is broken now. Buying another though, worth it.
