Breakwater Supply Explorer 25L Waterproof Kayaking Backpack with Phone Pocket

Enjoy the outdoors – without worrying about the water!

We’ve made it easier to enjoy the outdoors by giving you the ultimate safe-haven for your stuff: the fully waterproof Breakwater Supply Explorer Backpack. This lightweight, rugged pack offers unbeatable waterproof protection for all of your gear – including your electronics – with the versatility to handle work, travel, and adventure. Bring it all with you:
  • 25L (1500 cu in) main compartment, with an additional front waterproof pocket and front buckle strap (for bulky items).
  • For your tech: 16″ laptop sleeve and waterproof smartphone pocket.
  • Adventure-ready: The front and top grab handles feature carabiner attachment points on each side.
  • All-day comfort: Curved, ergonomic shoulder straps. Lightweight at just 1.9 lbs.
  • Zip it watertight: Unlike roll-top bags that require forcing out air, rolling and buckling – just zip the Explorer Backpack shut and it’s waterproof.
This pack’s incredible waterproof protection is achieved using drysuit-grade airtight zippers, high-frequency welded seams (no stitching), and our advanced waterproof Hydrowall material. This ensures water stays out and your gear stays dry and protected – no matter how wet it gets.
It totally meets and exceeds my expectations at first blush. It seems to be of terrific quality, and is certainly the best bag I’ve bought on Kickstarter to date. Gary, Kickstarter Backer

Waterproof Smartphone Pocket

The side smartphone pocket utilizes extra thick, clear, puncture-proof TPU. This is the same rubbery material used for waterproof phone cases. Since this pocket is only accessible from the inside, it’s secure and also completely waterproof. Your phone is protected from splashes, rain, mud, dirt, and sand. And to top it off, the touchscreen works from the outside, so you can control your phone without taking it out of your bag – a customer-favorite feature.

    Amazing back pack for water people; nothing like it out there. It is worth the money.

    This backpack is heavy duty! I work as a camp counselor at an outdoor camp and have used it in various weather conditions (rain/shine) and at different nature spots (lakes, waterfalls, rivers, trails, etc). I haven’t tested its waterproof claim yet (been meaning to do so in my bathtub), but I have worn it while it rained, and the stuff in my backpack was absolutely dry!

    The zippers are hard to move, but that’s because they are supposed to prevent water from seeping through. I do like how there is a pocket you can slip your phone into that you can see on the outside, and the material covering your phone is thin enough so that you can still touch your phone screen!

    I prefer this backpack to the other ones that have the openings at the top that you have to roll down – it’s so much easier just being able to unzip the backpack and grab what I need!

    I think the only thing that tripped me up at first was the price point, but, other than that…I would highly recommend this backpack!

    Just got back from a fishing trip wehre we had lots of luck. Brought this backpack with me and found it especially useful for the space it has and the waterproof abilities. Very well built. Plan to use it on similar trips in the future.

    Bought this bag as a comparison to a few others on the market, but this was better priced and had more features. I love the bag! Most importantly the pocket for the phone is what makes it the perfect bag when on the water.

    I bought my bag through the Kickstarter campaign. It totally meets and exceeds my expectations at first blush. It seems to be of terrific quality, and is certainly the best bag I’ve bought on Kickstarter to date. I can definitely see it being a hit with people who spend a lot of time around water. I closed the zipper and it retained the air inside, and like on the video I was able to stand in it and the air did not leave the bag. Love the small details like the phone pouch with the clear plastic and the water bottle holder on the other side. I also love the computer pouch inside- will definitely keep the electronics safe. Very glad I got the blue- it’s very pretty. And the thinner material c/w the black still seems plenty tough enough- although time will tell. It may be a limited run though.
    Have not loaded it up and carried it for a long time to see its comfort, but the straps and the back panel seem well made and likely will hold up with protracted use.
    The campaign was super slick and smooth and the product came through very quickly and 100% on time, something that cannot be said for most of the KS campaigns.
    Even my wife loves the bag, and she can be quite fussy around this stuff.
    All-in-all very very happy. Wish all the KS products could be as good. Well done guys (and gals).
