Excellent quality
Size: 30L Color: Blue
Absolutely fantastic bag. Very spacious very good construction. Compared to bags from outfitters this was by far a better choice for me and overall probably better construction and durability.

Great bag
Size: 40L Color: Grey
Gf stole mine. Had to buy another because it’s that good for the price. Lots of useable pockets and a couple even inside. I use mine often. The mini bag is also surprisingly useful.

Waterproof and works well.
Size: 20L Color: Grey
Large capacity and waterproof. Used while fishing to keep stuff dry and even survived a keys west trip in the down pour. Love the backpack straps for easy carrying.

Very dry bag, minimalist backpack, quality
Size: 20L Color: Yellow
The iDrybag is a well made dry bag of thick sturdy material. It has a deep internal zippered pocket and a couple of shallow open pockets I sideas well. No outer pockets except for the bottle carrier that can zip closed. The external pocket has a well covered zipper but it is not the sealing type. So weatherproof for sure but the out pocket will leak if submerged. A nice sturdy carry handle on the side, too. While advertised as a backpack it has no padding or plate for you back, just two clip on padded straps. OK for a short hike down the beach but not something you want to use primarily as a backpack. It is more like a very versatile dry bag, rather than a waterproof backpack. I work outdoors in the rain so this iDrybag is perfect to carry my lunch, electronics, spare batteries, heavy gloves, etc. I can even fit my heavier work raincoat in it, barely. Small enough to easily tote around and stash out of the way but big enough to carry all my personal stuff for a work day in the must and rain. Extremely happy with the dry bag especially at the price point. Superb value. I only mark it down a star due to it being advertised as a backpack at which it is minimally qualified. But as a versatile dry bag it is five stars. ... show more

Great for keeping things dry
Size: 20L Color: Yellow
Great product. Used for a family paddle board and kayaking trip. The bag is pretty deep and holds a lot. I was able to fit 2 swim towels, toddler swimmers, and to bags of snacks in it. It comes with the 2L bag which was handy and I was able to fit car keys and 3 iPhones in it.

Sturdy and more comfortable than expected
Size: 30L Color: Blue
Why did you pick this product vs others?: I got this to use as a day pack on a trip where it was supposed to rain a lot. I was surprised at how much i could stuff in there and it still feel comfortable on my back. There's two pockets, one inside and one outside and the little pouch was convenient for a few little things I wanted accessible. I didn't submerge it, but it kept the rain out and seemed air tight when I closed it, so I think this is a good, inexpensive option for anyone wanting to keep gear dry. ... show more
