Review on Grassman Waterproof Lightweight Swimming Kayaking by Chris Moody

I bought these for motorcycling and off-road hiking. It's hard to tell from pictures online whether you're buying rubberized nylon or a tough material like Tyvek. I was hoping for the former. You didn't disappoint us. The bags are really well made. super strong From a marketing perspective I was a bit disappointed that they claim they are 1-1/2" wide when in fact they are the same thickness as the other bags, just under 5/8" on all three bags. I thought maybe a really thick seam on a large bag that I didn't buy. At first it really only bothered me in terms of honesty and principle. I have used them. As you can see I still gave them 5 stars. Very durable. super easy. And 3 packs give me the choice. Seams shhhhh! It really is good value for money. I tie them to the trunk of my adventure bike and just start riding. I spilled a spill or two on the bike and the bike took the hit harder than the dry bags. I used 2 large bags as floats to cross the river on my bike. Maybe not as shiny as my DrySak, but just as functional and durable. Thank you Grasman!
