Buyer’s Guide: 3 Key Factors to Consider
Capacity & Intended Use
Think about what you need to carry. A small 2-5L bag is perfect for a phone, keys, and wallet. For a full day on the water with extra clothes and lunch, look for 10-20L bags or a backpack-style dry bag.
Durability & Closure Type
Roll-top closures are the standard for a reason—they create a reliable seal. Check the material thickness; heavier PVC or TPU-coated nylon (like the Big River bag) handles abrasion better than ultralight options for rough jet ski use.
Extra Features & Portability
Features like a clear phone pouch, backpack straps, or a bright color for high visibility add real value. A lightweight bag packs down small, but ensure it’s tough enough for your specific needs.
Frequently Asked Questions
Are all dry bags fully waterproof?
Most quality dry bags are waterproof when sealed correctly, but check the IP rating. An IP67 or IP68 rating guarantees protection against full, temporary submersion, which is ideal for jet skiing.
What size dry bag do I need for a jet ski?
For essentials only, a 5-10L bag is sufficient. If you’re carrying towels, a change of clothes, and supplies for two, a 20L bag or a 20-30L dry backpack is a better choice.
Can my phone go in any dry bag?
It’s safest to use a bag with a dedicated, hard-sided phone case (like the Pelican Marine bag) or a clear waterproof pouch. This adds an extra layer of protection against impacts.
How do I properly seal a roll-top dry bag?
Roll the top down 3-4 times, ensuring the roll is tight and even. Then buckle or clip the ends together. Always do a visual check that the roll is secure before hitting the water.
Do dry bags float?
Many do, especially when they contain air-sealed inside with your gear. Some, like the IDRYBAG Backpack, are explicitly designed to float, which is a major safety benefit if dropped overboard.
Final Verdict: Which One Should You Buy?
For most jet ski riders, the Sea to Summit Big River Dry Bag strikes the best balance of heavy-duty durability, reliable waterproofing, and practical size options. If you need maximum protection for critical electronics like your phone, the Pelican Marine Dry Bag with its hard case is the top choice. For those who want a hands-free, high-capacity solution, the IDRYBAG Dry Bag Backpack is incredibly versatile and built to last.
Your perfect dry bag depends on your cargo, but focusing on proven brands and robust construction will keep your gear safe and dry.
