These are our heavyweight ‘TrailProof ‘ vinyl waterproof duffel bags.

A much simpler design than our Lightweight Upano range – designed to be a simple and affordable option for outdoor sports.

Brilliant for watersports, paddling, camping, backcountry vacation, sailing and expedition use.

Key Features

  • These are tough and simple drybags which allow you to pack and go, wherever you need to go
  • They are made from tough 500D vinyl to withstand all the knocks that you experience on the trail
  • It is really simple to seal these duffels, just roll the top down 3 times. We have also added a Velcro® strip to make it even easier!
  • Four compression straps help to make a great waterproof seal
  • We have added simple integral carry handles
  • The bright color means you can easily spot your gear amongst everyone else’s, and it reduces how hot they’ll get if left out in the sun.

Roll up roll up!
Please note: You need to roll the bag very tightly to line up the two halves of Velcro. This is essential if you want your bag to be waterproof. One or two customers have suggested that we might use a wider strip of Velcro to make it easier to close. But if we did that, then your bag wouldn’t be waterproof.

  1. – On test: duffel bags reviewed

    The TrailProof Duffel comes into its own in wet environments, so is great for paddlers or anyone who wants to protect their gear against the elements, whether on a rain-lashed campsite or a winter’s day at the foot of a climb. It’s not designed for immersion, but it will protect against anything short of that as long as the roll-top is correctly fastened. Weight is low for such a tough-feeling bag, helped by its simple design, though the lack of a carrying harness might restrict its usefulness for some people. The price is good too. Comfort while carrying the bag was aided by the fact its fairly narrow but long shape minimises knocking against the legs.

    We loved the heavyweight Aquapac Duffel we did use on our trip. It was perfect!

  3. TRAIL magazine Gear Chooser

    A superb option for those who need to keep their gear dry, the Aquapac duffel is made of heavyweight vinyl and manages to be well-featured whilst remaining lightweight.

    This bag had been used to every extent carrying my dive and work gear in my van and offshore. Excellent build quality with an easy wipe clean exterior and of course water tight.

  5. SUP Mag UK

    With a robust and durable design, the bag’s 500D vinyl construction will take knocks and punishment from even the harshest of environments. Its four compression straps and nifty Velcro strip make waterproofing your gear super simple. It’s then simply a case of strapping the Aquapac TrailProof Duffel bag to your board and sweeping off… It’s perfect for keeping your stuff dry and compressing down to a manageable size for lashing to your board. This is one piece of adventure paddling kit you can’t do without.
