Waterproof Bags

Waterproof bags for kitesurfing, SUP and everyday use

Waterproof bags keep your dry clothes, electronics and gear protected when you’re near or in the water. They’re ideal for kitesurfers, SUP riders, beach lovers and commuters who want to make sure their belongings stay dry. From your first kite session to long SUP trips downwind, a fully sealed bag lets you relax knowing your kit is kept safe and sound.

A bag marked waterproof is built to handle direct contact with water and, in many cases, short submersion, while water-resistant bags mainly guard against rain and splashes. The IP rating shows how well the closure keeps out dust and water, helping you decide if a bag can manage light rain, spray or full submersion.

Types of waterproof bags and how to choose the right one

Dry bags are simple cylindrical pouches with a roll-top seal, ideal for keeping your dry gear together while kitesurfing or paddleboarding, or for making sure keys, towels and spare clothes stay dry at the beach. Waterproof backpacks offer the same level of protection with padded straps and back panels, letting you cycle to your spot, walk further or use the bag for college or work.

Waterproof duffel bags offer better organisation and more room for wetsuits, harnesses and pumps while keeping your car or public transport free from salty water and sand. Smaller waterproof cases and sleeves keep your phone, car keys and wallet safe, and can easily fit into a larger bag or be clipped to the deck of a SUP board.

• Dry bag: Lightweight, compact and perfect as an inner liner for larger bags or strapped to a SUP.
• Waterproof backpack: Handy for travelling to and from your spot and great for everyday commuting.
• Waterproof duffel: Perfect for travel, road trips and weekend adventures with plenty of wet kit.
• Waterproof cases: Made for small essentials and electronics that need that extra bit of protection.

Start by thinking about how you’ll be using it. For a typical kite day, a duffel around 60 to 90 litres gives you enough room for a wetsuit, harness and spare clothes, maybe paired with a smaller dry bag for your phone and keys. For SUP or kayaking, a backpack or dry bag between 20 and 35 litres will fit spare clothes, a wind jacket, snacks and safety gear nicely.

The size in litres shows whether you’ll have space mainly for smaller items or for a full set of neoprene and layered clothes. Materials like heavy-duty PVC or coated nylon deliver high durability and resistance to seawater, while welded seams and sturdy buckles cut down the risk of leaks. The carrying system is important if you walk or cycle longer distances, as padding and chest or hip straps make it much more comfortable.

Think as well about organisation. Simple dry bags often have one large compartment, while backpacks and duffels can include inner pockets, mesh and small compartments for electronics. For commuting, it’s handy to have a padded laptop section and a small waterproof pocket for keys and cards, so you don’t have to dig through one wet compartment for little things. When chosen well, your bag will suit both your gear and your clothing.

Use, safety and maintenance of waterproof bags

To make sure you get a proper watertight roll-top closure, roll the top at least three times before fastening the buckles. When using a SUP, secure the bag to the deck webbing or D-rings so it won’t move about if you fall in or take on waves over the deck. Pack with balance in mind so the weight is evenly spread and doesn’t tip too much to one side.

Bright colours or reflective details help you stay visible in cloudy weather or early morning and late evening. After use in salt water, rinse the bag with fresh water, open and close any zips a few times, and let it dry fully before storing. Sensitive electronics benefit from an extra layer of protection in a smaller pouch or inner bag, especially if the bag will be used in rough conditions or might end up fully submerged.
