Hands-free, worry-free, your gear stays dry from the put-in to the take-out.
- PVC waterproof shell tougher and more water-resistant than fabric alternatives, built for full immersion and heavy rain.
- Backpack straps on larger sizes the 15L and 20L come with double shoulder straps so you can carry serious loads without your hands tied up.
- Five sizes with carry options to match strapless 2L, single-strap 5L and 10L, double-strap 15L and 20L
You're loading into a kayak with both hands full of paddles and gear. The 15L goes on your back, straps tight, and you're free to handle everything else. Next weekend you're just carrying a phone and keys to the beach. The 2L clips to your waist or fits in a pocket. Same system, different size, different mission. That's the whole point.

FAQ
FAQ
Is PVC more waterproof than polyester dry bags?
- PVC is generally more rigid and offers stronger waterproofing, especially against submersion and rough handling. Polyester bags are lighter and pack down smaller. If you're doing serious water activities, PVC is the better choice.
Can I submerge it fully?
- It's built to handle splashes, rain, and brief submersion. Roll the top down tightly at least three times and clip the buckle before any water contact for the best seal.
Is it chemical-free and safe for food contact?
- The bag is confirmed chemical-free with no high-concern substances. That said it's designed for gear storage, not food.

Strap It On and Forget About It.
Load it, strap it, and your hands are free for the paddle, the rope, or whatever else is happening. PVC construction means it survives the trip without falling apart.

Nice thick waterproof material , came well wrapped in several bags , nice and quick dispatch and delivery
This is a heavy duty bag, made of a very durable vinyl which will last. It’s 2l in size but you’ll lose 1l once the top
I got this to hold the contents of a first aid kit i hang on my walker. The bag feels very sturdy and most of its fabric is definitely waterproof. I tested this by scrunching up some sheets of a4 printer paper, sticking them in the bag, and submersing the bag in a tub of water.
All of the sheets came out dry, except for the paper at the top. It got a little wet thanks to the seal made of a different fabric. It let in some air and i saw bubbles come out.
All things considered, i do recommend this bag.
