Initially Skepzis, but then convinces in use

I needed for a canoe trip even a waterproof backpack with straps. These are made of plastic, which read me doubt whether they also keep the weight off. Both carriers as well as closure have previously survived two canoe trips successful. For the price I think it's super. I am also sure that it will add a few more join He has not added any shortcomings. With sacks of Ortlieb and Co. Of course this is not to compare, but if you do not want to spend quite so much / can, is it well-advised with this product.
