Nice bag. I took it on its first trip over the weekend on my KTM 390 Adv. Fits nicely, I chose the 40L as my bike is on the smaller and lighter side. It held everything I needed for my weekend trip, a tent, sleeping bag, inflatable mat, pillow, clothes, food, etc. I had some tools and cooking supplies in the side bags, but this bag took the place of my backpack. Was on 30 miles of gravel and dusty paths, and the inside was completely dust free. Rode through a few puddles and everything was dry, although probably not enough water for thorough testing. Based on the material, roll top, and velcro closure, I cannot see why it would not be waterproof. I like the strap configurations and straps provided. Used them my entire trip. Great price point, will keep testing the bad and will report if I uncover any new details.

Tiedowns could be better for a luggage rack application. All in all, it seems to be descent bag. Using it for two sets of rain gear on the bike.

This is the best bag that I have ever bought, water proof, you can squeeze all the air out of the bag to make more room for more stuff .

Muy buena calidad

Very excellent product for motorcycles. We use it in a trip from California to Florida in summer, hitting the hurricane Laura, so we had more than one day and weather of trying this bag, excellent! Super well design to keep the attachments on the the bike, while you take out whenever you want to the rest of the bag. Huge capacity ( 65 lts). Very impermeable. No regrets!

This bag is huge. Has many ways of securing it to your motorcycle. This is a must have for traveling on a motorcycle.

We bought this bag to strap on the back of our motorcycle. It holds quite a bit and one has to be creative on how to pack this since it is just a big open bag. The nice feature is that it has a vent so you can take the excess air out to compact the bag to properly and firmly use the straps to secure the bag to the back of the bike. I would make sure you select the right size. I did not get the larger one and glad I did not. This one is huge and more than adequate to easily hold 1-2 weeks worth of clothes and toiletries for two people. Fold it up and secure if you have additional storage areas on your bike and it can be a back up storage if you find yourself out shopping and need to carry your items back home. Using a regular backpack was not recommended to use on the bike because the extreme wind and possible soaking rain could penetrate. This is marine grade and; is made to withstand the elements. Well worth the money. Would recommend

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.

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 am sure as long as the material remains supple it will be waterproof, but being vinyl it will dry out and crack. I assume. Take it for what it is worth
