Altatac Alta-Bag Waterproof Dry Bag Backpack 20L Dark Green

20 Litre Waterproof Dry Bag Backpack

The Altatac Alta-Bag is a 20 litre dry bag backpack built from heavy-duty 500D PVC composite fabric. It uses a roll-top closure to create a watertight seal that keeps contents dry, clean and protected from sand, dust, mud and snow. An adjustable, detachable shoulder strap allows it to be carried as a backpack. A splash-proof outer zip pocket provides quick access to small essentials.

Suited to paddlers and hikers needing full

Kayakers, boaters and campers who expect heavy rain, splashes or brief immersion will benefit from the roll-down seal and tough PVC construction. The single 20 litre compartment works best for users who can pack loosely and do not need internal organisation panels. Buyers who want multiple compartments, a framed back system or a dedicated laptop sleeve should look at something else.

Roll-top seal holds under continuous wet conditions

The simple roll-down top maintains its waterproof integrity during sustained exposure to rain, spray or sitting in a wet boat, unlike zippered bags that can leak over time. The 500D PVC material resists abrasion from sand and rocky shores during extended trips. The splash-proof outer zip pocket is not submersible and will allow water entry if immersed, so critical electronics should stay inside the main sealed compartment.
