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.

    Hello readers of the Breakwater Supply company reviews for the Explorer 25L waterproof backpack. I purchase my first Breakwater Supply bag in August of 2022. When it arrived in the mail it was on time with quick delivery. Showing excitement and ready to try out this new bag. Switching from a worn out a waterproof Patagonia 30L , after close to two-years of daily use. Which can be seen here on this YouTube:

    The switch from the Patagonia to Breakwater Supply was helpful in keeping items separated and organized. It also stored all the personal property allowing everything to stay dry. Lowering any stress one might have when getting caught in the rain or on the boat with water splashing on deck. This is an awesome backpack for organized onshore fisherman who carry all there tackle and want to keep it dry. The primary Breakwater Supply backpack I use goes through ups and downs daily, with an average weight of ten pounds in the bag. Holding everything one might need and use for a business administrative lifestyle. Which in this case is education while in college over the next few years. Here comes the good news, this manufacture stands by there product with professional customer service and has provided a brand new Backpack after mine became damaged. If your looking to try a waterproof bag this company is offering a water tight sealed bag.

    This bag will serve a dual purpose 1) travel either airlines or my car 2) to be placed in my basket on my E bike to go to the Lighthouse in the winter. It gets cold and windy at the top of the lighthouse. I dress down for my ride there but, need extra things at the top.

    So just to see how much I could take if needed I stuffed the bag. The following all fit in.; extra pants, long johns, rain jacket (Columbia fairly heavy), super thick sweatshirt, an additional pull over sweatshirt, knit hat, ear muffs , scarf, wool socks, thin socks, waterproof shoes or rubber covers (try rubber covers, galoshes for older people). Also small bicycle pump and repair tire kit.

    All in a waterproof bag. That keeps it shape and is very well made. Another plus it fit in my over size Electric Bike Company model R bike basket. Yet it also felt very good with great weight distribution, when I placed it on my back. Perfect as a carry on bag.

    By having all these options it was easier justifying the price. The old saying is “ you get what you payed for” in this case I got more in quantity, storage and waterproof. I received before the arrival date in excellent condition.’

    Tried to find fault with the bag. I could not. The bag has some reflective material that works well at night. If needed you can easily add a light to the bottom handle or a reflective belt around the bag.
