Bought a couple in different sizes for traveling in our airplane. I can get 9 days worth of clothes and my shoes in the 30 liter! Crazy !

I have a 1 liter stuff sack and a few of the packing cubes and they have made my backpacking and hiking life much more organized and helped cut down on some of my plastic usage. They are durable, tough, and easy to clean.

I have a 3L and a 6L stuff sack. Both have been used numerous times for backpacking. All I can say is that they’re amazing! The shape of the bag makes them perfect for stuffing into my backpack or even my suitcase. They’re also super lightweight, but also durable! Currently the 6L is being used as a bag for my GoPro gear. The 3 liter is used for misc. items that I need for a day on the trails. I’m at a summer camp a lot and these are perfect for that as well!

Fits just right. You could probably throw a hat or other item in there with it, too.

Exactly the right size for my puffy coat (Mountain Hardwear women's M - 650 fill). Easy to cram it in and draw it shut!

As with everything Osprey makes, this lil' stuff sack is made with quality materials and construction. That being said, make sure you have a good visual of what 1L looks like in reality. I bought this with the intention of using it to pack a puffy coat of mine and woefully miscalculated. I will need at least 2-3L for that coat. If you want a stuff sack for small items like wallet, keys, phone, a snack, etc., then this pack is for you! It would best function more like an extra pocket inside of your pack. Would give this more like 4 1/2 stars. I did find that getting things in the sack was difficult, but I could see where making the opening a little wider or otherwise more user-friendly may reduce the effectiveness of keeping things compact.

The ultralight stuff sacks are easy to use and work great as an extra barrier between my cloths and the rain when hiking or just a great organizing tool when traveling in general.

I use this stuff sack as a laundry bag while traveling. Its super light and has the capacity to fit all of the laundry I accumulate. The construction is good and it has held up to multiple washes itself!

Lightweight and great option for backpacking and international travel where space is tight, but you still want the organization of separate pockets.

Great lightweight sack that can used for just about anything. I have personally been using a 12L for a down synthetic blanket I have and has been fantastic.

Bought the 3L sack for my Mountain Hardwear StretchDown Plus Hooded Jacket. It's the perfect size for a puffy jacket.
