40L 500D PVC Dry Bag

The Unigear dry bag offers 40 litres of waterproof storage built from ripstop 500D PVC with high-frequency welded seams. A roll-top closure seals out water, sand, dust and dirt. Two adjustable straps let you carry it as a backpack. Reinforced D-rings and POM buckles handle heavy loads without tearing. It floats on water for extra security during river trips.

Who This Suits and Who It Does Not

Kayakers, boaters, anglers and campers who need a single large sack to keep gear dry will find the 40L capacity practical. Users wanting multiple compartments, a padded laptop sleeve or a smaller day-bag size should consider other options. The single main chamber and soft construction do not suit anyone needing rigid organisation or internal framing.

Roll-Top Closure With Welded Seams

The roll-top design combined with fully welded seams creates the waterproof barrier that protects contents from full immersion. No zip or hook-and-loop closure is used, so the seal depends entirely on rolling the top correctly. If you prefer a zippered opening or cannot ensure a tight roll every time, this closure style may not meet your needs.

Questions about this item

What gear should I already have to use the roll-top closure and D-rings on this 40L dry bag?

You only need to pack your items, roll the top down at least three times and clip the buckle; the bag itself supplies the roll-top closure, welded seams and two adjustable shoulder straps with reinforced D-rings.

Can I keep using my existing 10L and 20L dry bags alongside this 40L model on the same trip?

Yes, the 40L bag uses the same roll-top seal and welded-seam construction as the smaller sizes, so all bags share the same waterproof method and can be carried together.

How do I confirm the 500D PVC bag is sealing correctly after I close it?

After rolling and buckling the top, press the bag gently; trapped air should stay inside and no water should enter when the bag is briefly submerged or splashed.
