I cant say enough about this bag! I use it for storage on my motorcycle When touring. I have been using the 40L hiviz green which helps people see me. I have ridin in a lot of heavy rain in the last 4 years and it has never failed me, always keep everything dry! The durability is great, I am not careful with this bag. It holds all of my camping gear, it hasnt worn through from riding on my rear rack of my bike. Its just awesome, I am thinking about getting the 60 L size as an upgrade! You cant go wrong with this bag!

I have the 60L version and its a great bag. It fits well sideways and inline on my Harley Pan America. When I first got it I was worried it was too big, but once I packed it full of gear and strapped it on, it fit great. If you have panniers and are not going out for weeks at a time, Id recommend a smaller one. If this is going to be the only bag you carry and you dont plan on having a passenger, its the right buy.

Did the job. Kept it dry in the rain and mud. Year later, it holds up.

Does everything it describes it does.

Took this bag on back of motorcycle for 800 miles and five states. Amazing never let me down

We didnt use them on motorcycles, but on our thule rack. We had two bags which held a ton of things. The bags compress well and appear to be wet proof (no rain or water to check). We combined straps and tethered other things down. Drove and unpacked several times and they show no worse for where after 3 weeks on the road. I only gave 4 stars because I could imagine some water issues if the rain is hard enough. Definitely suggest these bags.

First time using a roll top waterproof bag. I was not disappointed with this product, 40 l size just right for a weeks trip on the motorcycle. Ran into heavy rain on the way back, riding two plus hours in light and heavy rain, bag kept all items nice and dry. Was easy to secure to luggage rack on the motorcycle trunk with supplied straps. Did not budge for the whole trip including at highway speeds.
