The Earth Pak Waterproof Backpack is a heavy-duty backpack designed to provide complete waterproof protection for your gear. It is perfect for traveling, kayaking, biking, commuting, camping, and fishing.

The backpack features a roll-top closure and single reinforced strip to ensure water stays out. Simply fold the bag down 3-4 times, buckle, and you are ready to go! The design is easy to use and provides a secure and watertight seal.

With plenty of extra storage options, this backpack is equipped with pockets on both the inside and outside of the bag. There's a large splash-proof zipper on the outside for quick grab and go items, and a built-in zippered pocket, mesh compartment, and key ring on the inside.

The Earth Pak Waterproof Backpack is also safe for travel. It is compact and lightweight, making it easy to carry on an airplane. The roll-top closure provides ultimate protection for your gear while traveling. The backpack also features convenient D-Rings attached to both shoulder straps and a MOLLE system looping, providing anchor points to latch onto while boating or biking.

For comfort, this backpack is built with an ergonomic padded backpanel, reinforced contoured shoulder straps, and a low-profile sternum strap. The design helps to distribute the weight evenly and take the load off your back. Additionally, a heavy-duty waist belt is included to relieve added pressure and support your load.

Now, let's answer some commonly asked questions:

How many cans of beer can I fit in this bag? Are the straps sturdy enough to support the weight?

I wouldn't recommend keeping beer in this, as it won't stay cold. If you are looking for a cooler/drybag, I recommend searching for Icemule. However, if you want an idea of what 35L means in real terms, you could easily fit a 30 pack of cans in here. Please note that if you add ice, it would be heavy and uncomfortable to carry. This backpack is better suited for storing clothes, towels, first aid kit, and lunch in the dry storage of a kayak.

What is the height dimension when rolled closed?

The pack is about 21 inches high if you fold the opening three times for a good seal. Folding it twice may give you another inch. The backpack is also 18 inches wide and has a 6-inch foot at the bottom, providing ample room for waterproof storage.

Is the bag comfortable to carry?

The comfort level of the bag is similar to any other pack. The main focus of this backpack is to keep the contents dry, which it does effectively. It offers the same level of comfort as any other backpack I've owned.

Is this material 500D?

No, the material used in this backpack is not 500D. It is 3D, meaning it has length, width, and height dimensions.
