FAQS
WHAT DOES 'QUICK SUBMERSION' MEAN FOR YOUR WATERPROOF DRY BAGS?
"Quick submersion" means that our waterproof dry bags can handle brief periods of submersion in water, such as when accidentally dropped or exposed to heavy rain. They are designed to keep your belongings dry during short immersions, but are not intended for prolonged or deep submersion. For longer or deeper water exposure, we recommend using our fully submersible waterproof cases.
HOW WATERPROOF ARE YOUR DRY BAGS?
Our weatherproof bags are foul weather and spray-proof, offering protection against rain, dirt, and dust. Our waterproof bags and backpacks are designed to handle quick submersion, providing protection if dropped in water or exposed to heavy rain.
WHAT’S THE DIFFERENCE BETWEEN THE WATERPROOF MAIN COMPARTMENT AND THE WEATHERPROOF ZIP POCKET?
The Coolers Dry Bags include an external weatherproof zip
pocket with an IP65 rating.
- The main compartment (IP66) is designed for quick submersion and will protect contents if the bag is briefly dropped in water.
- The weatherproof zip pocket (IP65) is foul weather and spray proof, meaning it can handle rain, splashes, and spray—but it is not submersible. Water may enter the zip pocket if the bag is fully submerged.
Tip: Store valuables, electronics, or water-sensitive items inside the main roll-top compartment rather than the outer zip pocket when in wet or unpredictable conditions.
CAN YOUR WATERPROOF MESSENGER BAGS SAFELY CARRY A LAPTOP?
Yes—but for optimal protection, we recommend using our Messenger Tidy - Large 15” insert inside the waterproof messenger bag.
While the bag itself offers IP66 waterproof protection, it doesn’t include built-in padding or compartments. The Messenger Tidy provides a padded laptop sleeve (up to 15") and multiple internal pockets to keep your tech and everyday essentials safe, secure, and well-organised.
Tip: Always use a padded insert or sleeve when carrying electronics in any dry bag or waterproof bag for added shock protection.
HOW ARE YOUR WATERPROOF DRY BAGS SEALED?
Our waterproof dry bags are sealed using our Fold Seal System™, which creates a tight, waterproof closure by rolling down the top of the bag multiple times and securing it with a clip or hook. This system, combined with high-frequency welded seams, ensures that the bag is fully sealed and protects your belongings from water, dirt, and sand.
WHAT MATERIALS ARE YOUR WATERPROOF DRY BAGS MADE FROM?
Our waterproof dry bags are made from a combination of eco-friendly TPU (Thermoplastic Polyurethane), nylon rip-stop, and PVC. These materials are chosen for their excellent waterproof properties, durability, and resistance to wear and tear, ensuring your belongings stay dry and protected in even the harshest conditions.
WHAT IS THE BEST WAY TO CLEAN AND MAINTAIN MY DRY BAG?
To clean your dry bags, simply wipe them down with a damp cloth and mild soap. If they’ve been exposed to saltwater, be sure to rinse them with fresh water to remove any salt residue. For stubborn dirt, you can use a soft brush. Avoid using harsh chemicals or machine washing, as this may damage the bag’s waterproof coating. After cleaning, allow your dry bag to air dry completely before storing it to ensure it remains in top condition.
WHAT IS YOUR EXCHANGE AND RETURNS POLICY?
We offer a hassle-free exchange and returns policy, allowing you to return items within a specified period for an exchange or refund, as long as they meet our return conditions. For full details on how to return or exchange items, please visit our Exchange & Returns Policy page.
WHAT’S COVERED BY YOUR 5-YEAR EXTENDED WARRANTY?
Our 5-year extended warranty covers manufacturing defects, including issues with materials, stitching, and zippers under normal use. It does not cover damage from misuse, accidents, or wear and tear. For full details and to view the warranty terms, please visit our Warranty Portal.
