Amazing product - great value!
I love them! Bought 3 of them. Colours are amazing, not bright at all, keeps your eyes off them (or thieves' eyes) while in transit. 3L capacity is plenty for my needs, at least in the situations I used them. Holds easily 5x 10k mAh, wires for all my gadgets (which are a lot of them), Spare batteries for the lights, and a set of pocketable waterproof coat and trousers! Do I have space left? Yes! The roll-top waterproof closure does it's job nicely. The hardened "lip" is not too stiff, so it fits in the backpack without problems. Waterproof-coated fabric and seams means dry stuff! Having an Osprey product at this price is great! Thank you! Recommended 100%. Did I say I love them?

Top quality space saving dry sacks for adventurers
I bought three Osprey dry sacks in different sizes to help organise my daughters rucksack and keep her gear dry on a Duke of Edinburgh hiking and camping trip. They work brilliantly! I am not an experienced explorer so wasn't sure what was good and what wasn't but liked the reviews on these. They are very light but strongly made. It took me a few moments to work them out but I was very impressed with the way they seal up. They seem to be like Hermione Grainger's handbag in the way they just keep on fitting things inside them! I really liked the way you can squeeze excess air out of them when loaded and they create a vacuum seal without using any additional tools. Saved loads of space in the rucksack. You then roll the top over for extra protection and clip it to form a handle. This struck me as a very clever piece of design making them easy to handle and can even clip on the outside of the pack, which is what we did to keep the essential snacks handy. On the hike and camping trip they worked brilliantly. Everything stayed in place and well sealed up with no moisture penetration or leakage out from used towels and clothes. Food crumbs and rubbish cleaned out of them easily on return too. When empty they pack away to virtually nothing. Definitely a great practical product.

Good quality practical item
Great product. Already had one they do the job of keeping your belongings dry in your pack when the weather is against you. Easy to use. Quality is good & I like the colour (albeit not the most vital of reasons 🤣) decent size for my day packs whether the 26 or 36litres and still leaves me with space for other items. Great for travel too as it compresses things down somewhat & can be used in lieu of a travel cube.

Too expensive
Great item… but overpriced

Dry bag.
This product is deceptive regarding internal size. It fits a king size 4.5 tog duvet without any real problem, a few shakes and in it goes. The product material seems quite robust & water proof although not tried the water proofing yet. The idea is to store the duvet in the loft till summer so needed something that is robust & this appears to fit the bill.

Worked as a Dirty Laundry Bag Backpacking
I basically used this to keep my dirty clothes in while backpacking Australia. It kept the smell away and my other clothes clean, worked very well as a laundry bag, can't say I tested it out in the rain but definitely kept wet towels and things from leaking into the rest of my bag.

Easy to open, close and seal. Seems watertight. Will buy a 6L version, too.

Mooi licht gewicht. Sluit goed af en is handig ok je tas netjes te houden. Ook gebruik ik ze soms als handtas als we tijdens een wandeltocht in een hotel zijn.

This is a very poor product. It tore in two places while in my backpack on a five day canoe trip the first time I used it. It’s a serious problem if you are counting on an Osprey bag to keep your clothing or your sleeping bag dry of you are using on a canoe, paddleboard or kayak trip. I have never had a dry bag or any stuff sack tear like that in 4 decades of camping.

Utilizzo sempre le Drybag per proteggere il contenuto del mio zaino dalla pioggia o umidità durante le escursioni o i cammini. Sono anche molto utili per suddividere il materiale e poterlo trovare molto rapidamente senza dover svuotare completamente lo zaino. In particolare questa della Osprey è davvero ben fatta, un materiale ottimo, resistente e leggero, che permette di comprimere il contenuto e ridurne le dimensioni e di conseguenza l'ingombro (io in particolare l'ho utilizzata per sostituire la sacca del mio sacco a pelo durante il Cammino di Santiago). Il prezzo non è propriamente economico, certamente se ne trovano altre ad un costo minore, ma la qualità dei prodotti Osprey è per me da sempre una garanzia e quindi ho preferito andare sul sicuro. Assolutamente da consigliare
