The Roll-Up Closure System

2020/7/14

Backpacks that utilize the Roll-Up Closure System have the benefit of increased water resistance and superior usability.

Water Resistance and Usability

The most common way to keep your pack's contents dry is to put a rain cover over your backpack. However, a rain cover won't keep the rain from running down your back. They also make it difficult to access the pockets and main compartments of the backpack. The challenge was how to make the backpack both highly water resistant and easy to use.
One solution is the Roll-Up Closure System when paired with the Aqua Barrier Sack, a waterproof inner bag. This elegant solution means you don't have to worry about getting your pack's contents wet in any weather, and you don't have to worry about putting a rain cover on every time it starts raining. It's also very simple and easy to use, allowing you to get in and out of the bag quickly at any time.

Two layers of fabric for extremely high water resistance

The Roll-Up Closure System is combined with the Aqua Barrier Sack. The simple pattern of the backpack's main body has minimal seams to reduce entry points, increasing water resistance. The Aqua Barrier Sack is made using a waterproof material with seam sealing. The Roll-Up Closure is airtight, helping ensure water does not enter the main compartment.

The Aqua Barrier Sack

The Aqua Barrier Sack is specially designed to nest perfectly inside the backpack's main compartment. The opening of the Aqua Barrier Sack has Velcro tabs that mate with the Velcro tabs on the opening of the backpack. This allows you quick access to your pack's conents because opening your backpack simultaneously opens the Aqua Barrier Sack. This system also allows you to quickly remove the entirety of your pack's contents because you can slide the Aqua Barrier Sack out of the backpack. This is especially useful for situations where your backpack may be wet and you want to keep the inside of your tent dry. Simply slide out the Aqua Barrier Sack and leave your wet backpack in your tent's vestibule.
A backpack with an Aqua Barrier Sack is extremely waterproof, but it is not suitable for use in situations with high water pressure, ie underwater.

Quick access to the main compartmen

Since there is no top lid, just unbuckle it for quick access to your pack's contents. To close it, simply roll the opening two or more times and buckle it.
