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.

Really great product, rollup duffel. Straps arrangement is good with stacking attachment option. Waiting to use it on long motorcycle trip and test it out with rainy weather. Giving 5 start as going to use as motorcycle language bag but things to note: 1. its rollup duffel no, chain - I like it as was looking to use on motorcycle. 2. it does not have firm/ hard base - which is good if you are planning to use for backpacking or motorcycle language bag. 3 4 compression straps- which is good if you are planning to use for motorcycle language bag. 4. Fully waterproof construction - which is good if you are planning to use for backpacking or motorcycle language bag. 5. No suspension system - makes it inconvenient for hiking or backpacking. 6. No outer pockets - makes it inconvenient for hiking or backpacking. 7. Single compartment and access it only from top rollup - makes it inconvenient for hiking or backpacking. 8. No loops or external straps - makes it inconvenient for hiking or backpacking.

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.

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.

After looking at a ton of drybags for long distance motorcycle travel, I bought the 60 liter in yellow for visibility on the highway in grey, rainy conditions. When it arrived, at first I thought it was too big but its actually perfect for my needs. You can cinch it down with the straps to make it smaller. It was nice being able to take my bulky jacket off in the sweltering summer Florida heat and easily store it in the bag, plus Im able pack an extra pair of motorcycle pants with protective armor (in a vacuum bag). This bag has traveled thousands of miles in monsoon downpours for hours and everything is bone dry. It attaches and detaches in seconds when I park for the night. I just throw it over my shoulder to check in to hotels. It still looks great and I get asked about it daily when traveling. It folds down easily when I store it in the garage. There are tons of ways to easily strap it to your motorcycle. Its a steal if you compare the price to the fancy motorcycle branded gear that cost an eye watering hundreds more. Definitely a home run and a no-brainer!

Great bag... packed a lot of stuff in it!!!

Seems it will work well in rain...soon as it does I know

This bag is sturdy, and has a air release. It really makes a difference when you roll it up. It also has strong straps for carrying.

This product was exactly as described. The 40l bag is perfect for packing and keeping things dry. It has plenty of straps for attaching to bike and I like the ability to get the air out through the valve to compress before attaching to my bike. The bag is large enough to hold 2 peoples things for probably a weeks worth of clothes.
