Using Your DryTide Waterproof Backpack

Check the Backpack Before Use

DryTide backpack is made out of very sturdy material but still punctures can happen, so make sure that you check the backpack before using it in wet conditions.

Closing the Backpack

The main compartment uses the roll down closure. The following images demonstrate how to correctly close the backpack:

First make sure the backpack is not overfilled (a little bit above the top lid is a good measure) so you have enough material to roll down. Then align the top edges of the main compartment and squeeze them together.

Tightly roll down the top of the backpack at least 3 times, 4-5 times is even better. Rolling the top tightly makes the seal better, still please check the end of these instructions for the roll down closure limitations.

There are two ways to secure the rolled top of the backpack. You can either buckle it to the side of the backpack (possible with the rainproof version of the 50L backpack)...

...or you can simply buckle the ends together. In this case make sure you bend the ends in the opposite direction towards the back, away from the side where you rolled the top down. This makes the seal better. This closure offers a bit better seal than buckling the ends to the side of the pack. On the other hand buckling to the sides keeps the backpack slim.

Here is also a quick video demonstration of how to close backpack by buckling the ends to the sides of the backpack (rainproof backpack):

How to close the backpack main compartment.

And here is a video demonstration how to close the 50L waterproof backpack and all the dry bags (shown on the 15L Bear dry bag):

When you close the backpack there will be air trapped inside. This makes the backpack (and dry bags) float if you drop it into the water. If you want to make it smaller, release the air from the main compartment before you close it (recommended when you want to use the backpack as a carry on).

The top and the back pockets use special rainproof zippers. Make sure you close the zippers all the way.

Taking Care of the Backpack

As said the backpack is very sturdy, but still it is recommended that you avoid putting it on sharp objects, thorns, dragging it over sharp rocks etc... If your backpack gets dirty you can simply wash it with water and hang it up to dry. There is a loop at the bottom of the backpack for easier hanging. It is also recommended you wash it with fresh water if the backpack was used in salt water to wash away the salt.

Also, keep solvents and insect repellents away from the bag.

Maximum Load

Backpack is designed to comfortably take around 15kg/33lbs of gear. Overloading the backpack for longer periods of time can cause tears in the stitching.


Backpack is NOT a flotation device and should not be used as such.

What Does Waterproof Mean

We suggest that you read our explanations on what exactly is the meaning of waterproof when it comes to waterproof bags and what can a waterproof backpack do. In short - even though the roll down closure is used in all dry bags our there it is not completely waterproof (even though the name "dry" suggests this and some stores/manufacturers falsely claim so). If the roll down is pushed under water for a longer period of time water will slowly start to drip in. It is not a dramatic flush of water that will ruin your things in a moment, it is a slow drip, but it is something to keep in mind. So to keep the inside of the backpack dry do not use it as a flotation device and do not push it underwater for longer periods of time. The zippers on the top and back pocket are rainproof meaning they will withstand rain but will slowly leak if they are put directly into the water. Again this is not a sudden flush of water, if you drop your backpack into the water I gives you enough time to pick it up before the pockets get wet. Also, make sure you close the waterproof zippers all the way. Because of these limitations we do not give warranty on backpack leakage.
