[Fully Waterproof Fabric] The entire seat bag is made of 500% PVC (Polyvinyl Chloride), making it completely waterproof. It keeps your belongings dry even in harsh weather with heavy, continuous rain. The PVC material is easy to clean, making it easy to remove stains.
[Large Capacity] With a wide range of capacities, from 30L to 70L, it can meet a variety of needs. The bag features an outer zippered pocket for storing wet towels and other items. It also features an inner zippered pouch for storing smartphones, iPads, and other personal items.
[Easy Installation] Once you're familiar with the accessories, it only takes 10 seconds to install and close. While zippered dry bags are prone to air leakage, roll-top dry bags offer exceptional airtightness and are easier to open and close. *Wrapping them more than three times will make the bag completely waterproof.
[Detailed Detail] The air valve removes excess air from the bag, creating more space. The thick shoulder pads provide extra comfort when worn diagonally. You can attach any pattern you like to the Velcro.
[Usage & Free Combination] Suitable for camping, fishing, diving, cycling, mountain climbing, skiing, traveling, etc. Two seat bags can be stacked to pack more luggage for long-distance travel.
