Osprey Ultralight Dry Sack

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?

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.

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.

Great item… but overpriced

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.

Lightweight and malleable. Appears to be relatively durable Ideal for use as a waterproof stuff sack for sleeping bag, allowing the shaping of it to suit your pack shape. Sleeping bag has always remained dry, although it hasn’t been subjected to any torrential downpours yet.

good for putting tech or a small amount of clothing into

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.
