    Perfect size for smaller MC!
  

*by B***N on Reviewed in the United States on November 4, 2022*

I use this on a 2021 Zero FX, essentially a medium sized dirt bike (450, 300, etc..).  I was looking for something that didn't look crazy big on the rear fender of the bike but still had useable storage capacity.  The soft sides allow it to expand vertically several inches and it will hold a full face helmet without a problem.  When its empty or only has small items the soft sides collapse down and give it a much more compact profile.  The bag has a bit of a wedge shape which matches the profile of the rear fender much better than a square or rectangular bag, which, combined with the lower collapsed profile looks great and matches the look of the MC.  I ordered this bag as well as this Kemimoto 30L Expandable bag (https://www.amazon.com/dp/B085997KQJ?psc=1&ref=ppx_yo2ov_dt_b_product_details) at the same time to compare.  The Kemimoto is a slightly larger capacity bag which would be useful, but the boxy cube look does not compliment the rear fender of my narrower motorcycle.The bungee string on the top of the bag has turned out to be more useful than I thought it would be.  There is a velcro panel on the top that opens easily to reveal a great pocket for quickly storing gloves or other small items.I custom mounted this bag to the rear rack already on my MC.  I cut some thin aluminum sheet metal to match the rack deck, placed the aluminum piece inside, on the floor of the bag, and bolted through the aluminum, through the bag, and onto the rack so this bag is hard mounted per se.  So I don't worry about leaving it in a public parking lot.  But I wouldn't leave anything of great value inside as there is no way to really lock the bag.  I also don't ever remove the bag so the supplied shoulder straps allowing it to be used as a backpack will never be used, but its an interesting idea.  I don't know how this bag would work mounted to the MC with the supplied straps, I don't think I would care for that to much on my particular bike.

    It works
  

*by G***Y on Reviewed in the United States on August 31, 2023*

Good quality. Appears sturdy and functional. The capacity is capable of holding an extra helmet. I have not used this overtime yet, the jury is out on deliberations on its durability.

    Love it!
  

*by G***A on Reviewed in the United States on October 19, 2023*

Exactly what I was looking for, nice looking and good quality.  Plenty of storage space.  I ended up using tie wraps to secure it to the rack but the Straps that come with would work fine also.  Great product for the price
