Osprey Ultralight Pack Liner

I like the Osprey brand. It has a name synonymous with quality. I had to buy two dry sacks one for the main compartment of my back pack and one for the lower sleeping bag compartment. This smaller sack will take the sleeping bag, mattress and silk liner.There is no joy in having wet kit when you unpack after a hard days hiking. These bits of kit keep your stuff dry and you happy.Some people say a back bin liner does the same trick. When sleeping in shared rooms, hostels or albergues, these are the people that wake everyone else up rustling their plastic bags as they pack up to leave early. Personally I prefer a proper seal on a dry sack.You may think that as your back pack has a waterproof cover, why buy these dry sacks. Two reasons, when it's wet it can also be windy and your cover may not stay in place, secondly sometimes it is too much hassle to take off a heavy back pack and put it back on for what might only be a short, sharp downpour.

The material is light , waterproof and robust . It works well as a waterproof liner for inside a large backpack (75+) , but i got it for a sleeping bag . The sleeping bag i have is pretty huge as i like my leg space (coleman) but the bag that came with it was not waterproof at the opening . I bought this and it has more than enough space for it, its quick and easy to pack/unpack things and it keeps my sleeping bag dry which is the main thing. Def recommend

Purchased for a walk around the coastline of Cornwall and paired it with an Exos 38 from Osprey. You definitely need a bigger litre size than the size of your backpack and this worked well and was certainly not too big. Got pretty blasted with rain on Day One with winds around 25 knots at times and no issues keeping things dry. Nice lightweight dry sack with a quality build. Very happy with it and will be purchasing again I am sure at some point.

Used recently for a wild camp and this pack liner was very impressive.Seems flimsy on first impressions but after taking it out on the Moors it held its own. Well made and robust. The leightweight feature doesn't detract from the quality. Recommend.

Nicely sized, fits my exos 58 well, though I tend to only half fill. Seems well built, I haven't used it long enough to comment on its longevity though I wouldn't expect any issues.Easy to clasp and keeps the water out as expected.Beats a bin bag.

I have used it in training, but am yet to use it on Snowdon October 2021.Fits my Osprey Talon 26 Backpack, perfectly, and I can pull the bag in and our easily.A good price too :)

It keeps my stuff dry so awesome liner fits in my ospray 55lt bag with way more room to spare

It's very lightweight and seems durable but I found the small to be too small for a 44 litre backpack despite it stating it was good for backpacks of up to 50 litres.
