Our Promise


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


Store everything you need for commute, travel, and adventure with 25L (1500+ cubic inches) of interior space. Plus with 20″ x 13″ x 7″ exterior dimensions, this bag fits underneath the seats as a personal item on most airlines. And for bulky items – like a jacket or that sweaty pair of gym shoes – you can quickly cinch them down with the front buckle strap.

Open Water

Get out there on the water! Splashes, puddles, and even submersion – no matter what, your stuff stays dry. The back and shoulder straps use fast-drying, non-abrasive padding for use during water activities like kayaking, paddleboarding, boating, and at the beach. And if it ends up overboard – or if you end up overboard – it floats!

Wet Weather – So What!

Because this backpack is made using welded seams, airtight zippers, and our fully waterproof Hydrowall material, it can withstand rain for any amount of time – so you can stay outside longer and without worry. Hydrowall is made using a double-sided TPU coating for incredible toughness and longevity. It won’t rip or tear, and doesn’t become brittle or break down.


  • Easily grab the pack from storage areas, back seats, or from the floor of your kayak/boat.
  • Carabiner attachment points on the sides of each handle for clipping extra gear.

All Day Comfort

  • S-curve ergonomic shoulder straps
  • Adjustable, removable and reflective chest strap with emergency whistle
  • Molded EVA back panel with fast-drying padding
  • Lightweight neoprene shoulder padding with reflective logo on right side

Interior Storage

  • 16″ padded laptop sleeve with velcro closure
  • Two 4″ x 6″ elastic mesh pockets – useful for cables and chargers
  • 6.75″ x 3.75″ internal smartphone pocket with clear window
  • 11″ x 7″ large interior zippered pocket

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.

Hydrowall Material

Our Hydrowall material has an advanced dual-sided permanently waterproof TPU layer that’s tough-as-nails and offers the same amazing performance in any climate. Along with the airtight zippers and high-frequency welded seams, this pack is a true safe-haven for your gear.


The Versatility to Handle Anything

What makes the Explorer Backpack special is that it’s rugged enough for adventure yet versatile enough for day-to-day life. It’s equipped to handle any activity or weather. With plenty of room, plus dedicated pockets to store your electronics, you’re covered whether out on the water, backpacking to bucket-list locales, or just heading in to work.

It Started on Kickstarter

After a successful launch on Kickstarter, we delivered this backpack to customers around the globe. Our two biggest reasons for creating this pack:
  • WATERPROOF PROTECTION WITH ZIPPERS: There’s plenty of roll-top waterproof packs out there, but those can be cumbersome and difficult to organize your stuff inside. So we set out to make a versatile, zippered waterproof backpack.
  • VALUE: Similar backpacks using 600D+ TPU and airtight zippers go for twice as much, and they don’t have a waterproof front pocket. Having more functionality than other products on the market, yet still being more affordable equals added value. Also – these zippers are drysuit-grade and do not require “zipper grease”.
The incredible features and capabilities that this pack offers are hard to find – and you’ll love it, GUARANTEED! If you’re not happy, reach out to us and we promise we’ll make it right.

    As someone who is constantly traveling, spending a lot of time hiking, kayaking, and exploring – this backpack is perfect. It’s waterproof, sturdy, has a ton of space, and looks great. Highly recommend!

    I’ve had my breakwater supply Explorer for about 6 months. I live in central Florida so the waterproof-ness gets a workout. I’ve been traveling all over the world with it and it has proven time and time again to be a reliable travel companion. Some of the stitching was coming loose on the top handle – I reached out to customer support via their website to report it. They responded in less than 24 hours and after providing a few more details a new bag was in the mail and heading my way. I’d happily recommend this bag to friends, family and everyone else!

    Worked perfectly, tough material, waterproof, easy access to essentials.

    Was looking for a waterproof daypack (which this is) that would be easy to take as a carry on for our plane ride along with hikes and such. When I received it, it was really quite large, and the zippers were wide and hard rubber and extremely hard to zip and unzip. This would not be convenient for easy access for anything. So ended up returning it and ordering a different pack which was much easier to zip and unzip and handle.

    This backpack exceeded my expectations at all levels! This backpack is 100% waterproof guaranteed! I was walking in a heavy down pour for several hours and all my personal belongings inside the backpack were dry.

    It is very comfortable to use this backpack while walking for several hours even carrying heavy size items due to the padded back support.

    I recently travelled with this backpack and it was really convenient because the backpack perfectly fitted below the sit inside the airplane and also it fitted perfectly on top of my 20” carry on luggage (it stands up-right on its own).

    I love all of the small details of the backpack, such as the carabiner loops (I used them to hang misc small items), waterproof phone pocket (I can use while being outside in a downpour or water-related sport or activities), and the mesh water pocket (I use my Miir 25.3 oz water bottle and it fits perfectly)

    Also, inside of the backpack it has a laptop sleeve (fits my 14” laptop perfectly) which is convenient when working remotely or working on the go). Moreover, it has two small pocket organizers that is useful for small size items like carabiner loops, portable chargers, etc. Also, it has a medium sized-zipper inside which you can use to store additional items.

    If you’re looking for a 100% waterproof, strong material, versatile use (commute, hiking, traveling and water-related activities or sports), then this is the ideal backpack for you.

    P.S. The only small quirk with the backpack is that due to the welded and waterproof zippers, it is kind of a struggle to open and close the zipper. However, there’s a simple solution. You can either use a lip balm or a silicone lubricant and the backpack will open and close very smoothly.

    Enjoy this Amazing backpack! 🙂
