I had the chance to use this on a week long river trip. It works great just like all of Seal Line's stuff but like the first review says the handle makes for a hard carry. I was lucky and was with a friend who was using the same bag and if I carried both at the same time it would balance out. A few bucks more will get you the shoulder straps and is well worth it. I would also recommend the larger version because packing can get tight for a long trip. I pack pretty light as it is but if you are not familiar with this size bag opt for larger.
This bag did what it was designed to do, carry a lot of clothing and camp gear and keep it dry. The downside is that with everything packed the single handle is out of position for balance and easy carrying. If I had to say I was 100% satisfied I would have to say not. If I could do the decision and purchase process over again I would have stepped up to the backpack style of this product.
