“These bags are tough and waterproof. Gives you peace of mind when transporting things that need to stay dry.
Only a few downsides:
1. Not having sleeves or inner pockets means that things will rattle around if the bags aren't packed tightly or padded with something else, so would recommend protecting things like laptops inside by something soft.
2. The velcro fasteners aren't easily detached/reattached, so I typically don't take them off - clips are better.”
