Key Features

  • This is our range of TrailProof™ heavyweight vinyl waterproof drybags..
  • This is our new version – now in 2 colors, and supplied with shoulder straps.
  • These are tough and simple ditty bags which allow you to pack and go, wherever you need to go. Brilliant for watersports, paddling, sailing and expedition use.
  • A much simpler design than our Lightweight range, they’re designed to be a simple and affordable option for outdoor sports.
  • They’re made from tough 500D vinyl to withstand all the knocks you experience on the trail.
  • It’s really simple to seal them – just roll the top down 3 times.
  • The bright color means you can easily spot your gear amongst everyone else’s, and it stops the bag from getting quite so hot in the sun.
  • You can depend on Aquapac’s manufacturing quality – we’ve been selling premium-quality waterproof bags for over 30 years.

Care Instructions

Our materials are strong but can still be punctured. Avoid sharp or abrasive objects and protect from impacts. After regular contact with chlorinated or salt water, or with sun creams, wash in soapy water and then rinse with fresh water. Do not use bleach, alcohol or proprietary cleaners.


  1. The strap makes these more expensive than a simple drybag, but they’re probably worth it… Simple. Utterly practical.

  2. This heavy-duty, rugged drybag will keep your kit nice and dry. I think they are ideal for session anglers and those fishing aboard a boat. They come with a handy shoulder strap.

  3. Due to customer demand Aquapac has re-developed its TrailProof 500-Denier drybags. The 7-, 15-, 25- and 70-litre bags now all have a useful shoulder strap.

  4. The Aquapac Trailproof Drybag is a must for protecting your kit in wet weather
