Protect your gear and keep it organised with fully waterproof, colour-coded dry bags for inside your pack.

Keeping all of your gear organised and protected is a concern wherever you are and whatever you're doing.

Osprey's ultralight and tough drysacks are made from siliconised ripstop nylon, so you can trust them to keep your kit protected and visible even in the darkest depths of your pack, and let you colour-code your contents for even quicker access.

They're equipped with a fully waterproof roll-top closure, coated fabric and taped seams that keep whatever's inside dry no matter how wet your pack gets.

Unlike other drysacks they are rectangular, which makes for more efficient packing and means that they can stand unsupported when removed from your backpack.

What are you waiting for....  make sure your gear is protected!

  • High visibility, with reflective graphic print
  • Fully waterproof roll-top closure
  • Fully waterproof coated fabric and seams
  • Rectangular shape for efficient packing
  • Weight: 0.05 kg
  • Maximum dimensions: (mm) 420 (l) x 260 (w) x 160 (d)

Great Dry Bag

This 20l Dry Bag is very lightweight, but seems well made and durable. Recommended.

Osprey ultralight daysac

I bought it to line a now porous daysack & it serves that purpose well despite all the recent inclement weather threw at me (& it)

Pretty handy

it’s a dry bag. What can I say? It keeps stuff dry, decent roll top closure, more lightweight material than rivals but Osprey make their rucksack rain covers from the same ripstop material - so far, seems tougher than you’d expect for the weight. The unique selling point is that it has a square base, which makes far more sense when packing stuff into a larger bag. Dimensions on the two I have are accurate, but remember that part of the ‘height’ is used up rolling the top to seal.

Dry bag

Great product, well priced, lightweight and keeps your stuff dry. What more do you want from a dry bag.

Osprey Ultralight Drysack (20L)

My Sleeping bag fits in with its compression bag. Helps to keep it dry as it is a down bag. Colour allows it to be seen in the dark. Like all Osprey products quality.

Great quality

A simple design which is great quality and functional along with being easier to see in the dark.
