The protection rating of the watertight bags

Picksea offers you in its category "Waterproof bag" that bags designed to withstand both water and sand....

Usually made with thicker fabrics to provide better resistance to abrasion and impact and to ensure optimal impermeability, we find PVC or nylon bags, which are widely used in the marine environment. The most effective fabrics in extreme conditions are above 600g/m², they will be thick and strong enough to avoid tears and tensions.

The IP rating is an international standard for assessing the tightness of a bag. It is measured on a scale of 1 to 8 for moisture. Picksea offers in its "leak-proof bag" category only bags that meet at least IP X4, which corresponds to a proven resistance to rain.

The different types of closure

The seams are the weak points of the bags, most of them are thermo-welded at high frequency to avoid water infiltration but 3 categories exist for the closures :

  1. The 3-turn folding closure. Efficient and with an incomparable look, it allows a quick total immersion in water while protecting its contents from water and dust.
  2. Zipped bags. More practical than bags with foldable closures, they are sometimes lined with a protective flap when the zip itself is not waterproof. Note that bags with the patented TIZIP closure are IPX7 waterproof. All zip bags allow better access to the contents without having to unpack everything.
  3. Submersible cases. The must to protect your electrical equipment, they are resistant to both dust and water. With a removable foam interior, they provide perfect protection with their rigid shells and O-rings.

The different types of waterproof bags

  • Large bags can be transformed into backpacks by using the shoulder strap handles.
