Water Resistant Bags
Waterproof Rating Class:1 – IP64
Water resistant bags can withstand light rain and splashes only. Usually made with specially treated material that resist water. Typically, they are made from a tightly woven fabric so water won’t penetrate in light rain situations. However, water can eventually penetrate after a certain amount of water exposure or water pressure.
Water resistant bags will withstand light exposure to water. However, in situations such as a heavy rain or high seas, expect your gear to get soaked! These bags are not waterproof. Bags such as golf bags, totes or the average school backpack are generally water resistant only.

Waterproof Bags
Waterproof Rating Class:2 – IP65
Class 2 waterproof bags sit slightly above water resistant. These bags are waterproof in certain situations. However, dependent on the force or direction of the water, they could still be permeated by water. Therefore this classification of waterproof bag does not have the ability to be submersed.
Waterproof Rating Class:3 – IP66
Class 3 waterproof bags will provide you with complete protection from water. Correctly sealed they will easily float if dropped in the water and can withstand a quick submersion. Overall, waterproof bags are suitable for boating, kayaking, where there is a chance of heavy rain, high seas or capsizing.
In general, waterproof bags are usually made from materials such as PVC or TPU making the fabric impervious to water applications. Bags made of PVC or TPU fabrics are constructed with heat welded seams. Therefore contain no needle holes. No holes = no leaks.
Waterproof bags sealed using a roll top closure system work best. The roll top closure set up allows you to secure the opening by rolling up to 3 or 4 times to create that waterproof seal.
In conclusion, this is where we come in. North Storm bags have a waterproof rating of Class 3: IP66 and constructed with the roll top closure system. Our bags can handle a quick submersion and have the ability to float.
