Did not receive

I picked these up as something of a goof, unsure of how I would use them.
I don't know about bicycling or camping with them (they seem kinda heavy), but they are great for keeping items dry in the slush of a cooler. Nicely waterproof, with a good anti-shock feature due to the thickness of the silicone. Thumbs up...

HYDRONER 20L BACKPACK

We love our bags we ordered! We also had a return to make and this company was great to work with!

Great size and completely waterproof!

Much BIGGER than I thought but will be great to take to the beach!

I am extremely happy with this product!!

WATERPROOF LIGHTWEIGHT 30L BACKPACK

Second one. Daughter took first.

The optivate bag is a nice size and great quality. I have been buying gecko bags & coolers for years now as I love all their products

I love my Hydroner Backpak. I use it on my sailboat, jetski & kayak. I'm always holding everyone's phones so the electronics are safe even if we do ditch. With a spare change of clothes in the bottom - for the ride home.

But I was disappointed after more than a year of use, when a side seam opened up meaning the backpack was no longer safely watertight. But it didn't take long for Geckobrands Support to make it right. Their lifetime warranty is exactly that. I sent them a photo of the bag and in 3 days I had a new one - happy and dry for our next water adventure.

Special thanks to Amanda ... You rock!

We took this pack on our kayak trip on the Current river. It kept everything completely dry even after being submerged several times. It also works well as a cooler keeping thing cool even when the air temps were in the 90s.

Easy and quick in to and close. Rain, snow and at the lake. Sadly not long ago it did fall into the lake and though waterproof still should not submerge it in water or sit a too long in a puddle of water. Water will find its way in.

So handy!
Nice quality, use of phone w/o removing!!
Has inside zippered pouch- room for lipstick and/or key fob.

My camping supplies are so organized and easy to find in this.
