Frelaxy Waterproof Dry Sack 5 Pack (3L,5L,10L,15L,20L), Ultralight Bags, Outdoor Sack Keeps Gear Dry for Hiking, Backpacking, Kayaking, Camping, Swimming, Boating

I tested how water proof these bags were by filling them with water and looking for leaks. I have to say I was quite impressed. Finding only one to have a small drip which as a camper / kayaker, this was well in the acceptable range. Under normal conditions you wouldn't have this kind of pressure pushing on the bag, if it were it would likely be on the bottom of a lake and thinking you wouldn't be going after it.

These bags are an affordable option than some of the other ultra light bags out there, but they are definitely not waterproof. I recently took these on a long distance thru-hike and sadly these did not hold up well after a short period of rain. I used them to contain my food/odor items and suspended them overnight on a bear cable. In the morning, there was several inches of rain inside the bag, despite the bag being tightly sealed overnight. I had to empty the contents and dry out the bag in the morning…needless to say, this is not a ‘dry bag’ and was a slopping wet bag that I had to try to dry out on the trail. The bags are convenient to hang and the roll tops are nice, but don’t expect these bags to keep your stuff dry at all.

Follow up: company kindly contacted me and offered a full refund. Many thanks for those whom own their products and back up.Definitely recommend doing businessDisappointed that one of those bags did not do its job to keep water away from the bag.

Me gusto lo practico que son ademas de que son impermeables..

Unfortunately after just one be hike, the seam seal tape on the inside of ALL the bags has come loose, making the bags no longer water proof. VERY DISAPPOINTING!
