You leave home with the weather looking fine, but a few hours later the rain starts. Your phone, spare clothes and other essentials are suddenly exposed to water.
With the DryTide 18L Waterproof Backpack, you do not have to change your plans when the weather does. Pack what you need for the day, close the roll top properly and keep your gear protected from rain, splashes and wet conditions.

It is compact enough for everyday use and light enough to carry comfortably all day. Take it to work, on a bike ride, to the beach or on a day hike, and keep your gear dry wherever the day takes you.

WHY WE MADE IT

We wanted a waterproof backpack for the days when you do not need a large pack, but still want reliable protection from water. The 18L is the smaller version of our classic roll top waterproof backpack. It gives you the same waterproof construction, comfortable carry system and practical storage, but in a more compact size that is easier to carry every day.
It is made for the gear you actually need on a day out: a change of clothes, water bottle, electronics, snacks and other essentials. The 18 litre capacity keeps the backpack compact without giving up the waterproof protection you expect from DryTide.

Whether you are commuting, cycling to the beach, exploring a new city or heading out for a day hike, the idea is simple: carry what you need, keep it dry and do not let the weather decide your plans.

FREQUENTLY ASKED QUESTIONS

Is the DryTide 18L Backpack completely waterproof?

Yes. The backpack has a fully waterproof construction with ultrasonic welded seams and a waterproof roll top closure. When properly closed, it protects your gear from rain, splashes and wet conditions.

Does the 18L Waterproof Backpack float?

Yes. When properly closed with sufficient air trapped inside, the backpack floats on water. It is not intended for prolonged submersion.

Is the 18L backpack suitable for everyday use?

Yes. The 18L is a small waterproof backpack designed for everyday carry, commuting, cycling, day trips and other activities where you want waterproof protection without carrying a larger backpack.

Can I carry a laptop in the 18L backpack?

Yes. The removable internal pocket can be replaced with an optional DryTide Laptop Sleeve, providing dedicated protection and organisation for your laptop.

How much can the 18L backpack actually hold?

The nominal capacity is 18 litres, while the measured capacity is approximately 20–22 litres depending on how much the roll top is rolled down. The roll top also allows you to adjust the backpack to different loads. The backpack will hold your laptop together with a sweater, few tshirts, snacks, camera, small toiletry bag and other small essentials.

Is the hip belt removable?

Yes. The 18L backpack comes with a removable padded hip belt. Use it when carrying heavier loads or when you are moving actively to keep the backpack secure and reduce movement. Remove it when you prefer a simpler setup.

Is the 18L backpack suitable for cycling and hiking?

Yes. The padded shoulder straps, padded back panel, adjustable sternum strap and removable hip belt make it suitable for cycling, day hikes and other outdoor activities. Its compact size makes it particularly useful when you do not need the capacity of a larger backpack.

How do I clean the 18L Waterproof Backpack?

Rinse the backpack with fresh water after use, especially after exposure to saltwater. You can use mild soap if needed. Avoid harsh chemicals and solvents, and rinse the zippers with fresh water after saltwater use.

Can the 18L Waterproof Backpack fit under an airplane seat?

The 18L backpack measures 29 × 13 × 48 cm when the roll top is closed. Its width and depth are within the 40 × 30 × 20 cm personal item size used by airlines such as Ryanair and Wizz Air. This makes it a compact carry-on backpack and personal item for air travel.

The height can be reduced because the backpack has no rigid frame or hard panels. If you do not fill it completely, you can roll the top further down and compress the backpack to fit the available space under the seat.

Airline baggage limits vary, however, so always check the current personal item and carry-on dimensions for your airline and fare before travelling.

Is the 18L Waterproof Backpack suitable for photography?

Yes. The 18L backpack has enough space for a camera, lenses and other photography gear, while its waterproof construction helps protect your equipment from rain, splashes and wet conditions.

The backpack does not have built-in padding or camera-specific compartments. For additional protection against knocks and impacts, we recommend using a padded camera cube or protective insert inside the backpack.

Does the 18L backpack have a padded interior?

No. The inside of the backpack is intentionally unpadded.

The 18L is designed to carry a mix of everyday and outdoor gear, including clothes, towels and other items that may get wet. Keeping the main compartment unpadded means it does not absorb water and can dry more easily. For laptops, cameras or other fragile gear, you can add your own padded sleeve or protective insert.

What warranty comes with the 18L Waterproof Backpack?

The DryTide 18L Waterproof Backpack comes with a 1 Year Limited Warranty against manufacturing defects under normal use.

  1. Lauren Mann

    This is the most well constructed dry bag I have ever owned! I swim out to boats most mornings for work and trust it to keep my stuff safe and dry. The features are so well thought out, it really is the perfect day bag! I really love the waterproof zippers/pockets on the outside- something that is lacking in most other’s I have seen. It also looks great and of high quality.

  2. Coco

    I have both the 30L and the 18L version, I use the 18L daily, 30L is better for 1-2 day trips.

  3. Martijn Met

    Excellent backpack. Exaclty I was looking for. Convenient, handy, and tough. Great service of the drytide organisation. And quick delivery.

  4. D2

    I finally found the perfect boat bag for fly fishing. The 18L backpack is the right size to hold my fly boxes, rain protection, and gear for a day on the flats.

  5. Renata

    This thing can survive an apocalypse!

    Hands down the best backpack I’ve ever owned. I used it as my carry-on for a month-long trip to Indonesia at the beginning of rainy season, and it handled everything—from rough open-sea boat rides to multiple scuba outings and days of traveling on boat. I got caught in brutal rain on an multi day volcano hike, and while my goretex shoes and jacket got completely drenched, all my gear stored in this backpack stayed safe and dry. It packs a surprising amount, offers super easy access, and is incredibly simple to open, close, and clean. The construction is rock-solid, and even after long days of trekking, my back never hurt. Truly an exceptional, go-anywhere backpack.
    And I got a lot of compliments on how cool it looks. 10/10

    I’m still in love with this bag after using it almost daily for more than a year now.
