Submersipack Waterproof Backpack - Inflatable Floating Dry Bag 25L

In this review of the Submersipack Waterproof Backpack the bottom line is simple: it is for outdoors users who need a truly floating, protective pack that keeps valuables dry without adding bulk. The defining reason to buy is the inflatable, submersible design that provides positive buoyancy so the bag stays at the surface rather than sinking with your gear. The reviewer found it particularly useful for kayak and fishing trips where space is limited and the ability to float the pack alongside you reduces worry about lost items.

Key Features

• Inflatable float: Blow air through the valve to inflate the pack so it will float beside you and keep contents from sinking during water activities.
• TPU coated nylon: The tough coated fabric resists punctures and abrasion for longer life on rocks, docks, and boat decks.
• Airtight zipper: Extra-strength waterproof zippers create a watertight main compartment when properly seated and lubricated, keeping clothes and electronics dry.
• Comfort details: Foam-padded shoulder and back panels with adjustable sternum and hip straps make it comfortable to carry on hikes or long paddles.
• Organizational pockets: A front water-resistant zip pocket, two mesh bottle pockets, D-ring and web loops keep small items accessible and allow extra gear attachment.

Who It's For

The Submersipack is best for paddlers, anglers, boaters, and beachgoers who want a reliable dry pack that also floats; inflatable buoyancy is ideal when you need the bag to remain accessible in the water. It also suits hikers and cyclists who value a durable, weather-resistant backpack with quick-access pockets and a reinforced bottom.

Those who should look elsewhere are users who expect a soft, roll-top dry bag style or need ultralight minimalist packs; the Submersipack is built for durability and flotation rather than minimal weight. Also, buyers unwilling to maintain the specialized zipper with the included silicone grease may find the zipper initially stiff.

Pros & Cons

Pros

• Floats reliably when inflated, keeping gear from sinking during water incidents.
• Durable TPU coated nylon construction resists tears and cleans easily with soap and water.
• Comfortable carry features including padded back and adjustable sternum and hip straps for longer trips.
• Useful organization with front water-resistant pocket, mesh bottle pockets and attachment loops.

Cons

• Watertight zipper requires lubrication to function smoothly and can feel stiff until broken in with the included silicone grease.
• Some customers report mixed long-term seam and zipper durability, so heavy daily abuse may reveal weak points.

Our Verdict

The Submersipack Waterproof Backpack is a practical, value-focused choice for paddlers and outdoor users who want a pack that both protects gear and floats. It trades ultralight weight for a more durable TPU shell and a specialized airtight zipper; when cared for with the included lubricant it performs well and is worth the purchase for anyone prioritizing waterproofing and flotation.

Frequently Asked Questions
