Key Features

  • This is our range of TrailProof™ heavyweight vinyl waterproof drybags..
  • This is our new version – now in 2 colours, 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 colour 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.

  1. Wired for Adventure magazine

    This is a drybag built with more than just keeping your clothes dry in your rucksack in mind. While it will do that, and do that very well (it’s fully waterproof and super abrasion resistant), it is also really well suited to other adventures. It has a carry strap which is really useful for slinging over the shoulder and we feel it would serve you very well on kayaking or stand up paddle boarding trips. You can just about fit a three season sleeping bag in there and the clips are large and tough. There’s no hook at the bottom but there are two solid D rings at the top. As the name suggests, it is a heavyweight bag, so it might not be quite as ideal if you’re packing light. 8/10.

  2. Fly Fishing & Fly Tying magazine

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

  3. Angler’s Mail

    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.

  4. TGO (The Great Outdoors magazine)

    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.

    The TrailProof Drybag was a life saver at our race this weekend. Lots of paddling in rainy conditions.
