I have had these a couple of years now and they have been great so bought a second set for my girlfriend to use.
Good price. Waterproof and do the job
Used these bags for varied uses from keeping items dry in backpac, carry drinking water in the mid size bag as one of the team broke his waterbottle and another used as a waterproof bag for keeping food in. Not a failure from any bag for all these uses. Very handy to have in the car also. I will be getting some more.
proved to totally waterproof & have many uses.
Will keep stuff dry from light rain and snow but not submersed as the seal isn't airtight I also can't void the bag of air and compress contents like other roll sacks. But still very light bags good for keeping damp and dirt off of your stuff with room to breath.
Low weight and waterproof material
Seal isn't air tight like other wasterproof sacks
