Experience the ultimate freedom of moving between land and water with this revolutionary new waterproof backpack.




This revolutionary new waterproof backpack has been designed to give you the freedom to explore and flow across land and water in search of new adventures.

Packed with all the essential features for safety on land and in the water this inflatable backpack is unique! With a zipped top style opening, removable back panel and harness, external compression straps and a tow system it provides a quick and easy way to explore off the beaten track. 

The pack was designed with open water swimming in mind but is equally at home on the deck of a SUP, as a first aid safety bag, for kayaking or sailing and can also be used as carry on luggage when flying.


The concept

To explore the rugged Cornish South West coast we knew we needed to create something tough, waterproof, lightweight, functional and with enough space to carry all of the kit needed for a fun day out on the water. 

When researching different factories to work with we were introduced to an inflatable waterproof zippered bag used by the military for transporting rocket launchers across water. From there, an idea was born.

AquaTrek®36 – a backpack built to move between land and sea.

Built for water

The AquaTrek®36 has been used by open water swimmers, sailors, kayakers, water-sports instructors, lifeguards and in remote locations on expeditions in Norway, Greenland, Alaska and the USA.


What the press says:

“Newcomer to the swim market Ulu have hit the nail on the head with the Aquatrek, a great hybrid of a backpack and a drybag ideal for anyone who likes to adventure both on and off land”

Sian Lewis / Yachting World

the aquatrek is ideal if there’s a large chance of your bag being dropped in the ocean or needing to be transported with you across a body of water

Andrew Lloyd / 220 Triathlon

Since I have had the Ulu AquaTrek 36, produced by a Cornish company founded by a former RNLI lifeguard, I have not been out on the water without it
