Innovated lightweight and durable waterproof stuff sacks that protect your gear and clothing from water and moisture. These stuff sacks ensure clarity and organization of your equipment in your backpack during long trips. Thanks to their new oval shape, they efficiently fill the space in your backpack without leaving empty, unused areas.
This could come in handy for you.
The stuff sack is constructed from 70D nylon with a PU coating, and its water column is 10 000 mm. The stuff sack has double-stitched and taped seams. The inner material is white, which makes it easier to find things as it is not “dark” inside the stuff sack. They are available in several color options, making it easier for you to organize your gear. For example, you will know that your clothes are in the blue stuff sack, while your down jacket is in the orange one. Occasionally, it's handy to hang the stuff sack somewhere, which is why there is a sturdy ring at the buckle of the roll-top closure.
The bag also functions as a compression sack, which is useful for compressing otherwise bulky down sleeping bags, down jackets, or other gear. Just squeeze the air out of it and roll the closure a few times. Air will not get back into the sack, and the gear will remain compressed – compact.

Compared to proven ultralight bags Ultra-Sil, Lightweight series is a bit heavier, but it is also more durable.
We recommend Lightweight Dry Bags if you require higher durability, for example, if you plan to attach the bag externally to a backpack or handlebars on your bike. They are also more suitable for storing heavy items, such as food, which can sometimes come in packages with sharp corners. You simply don't have to be as cautious with Lightweight stuff sacks while using them.
If you're looking for a waterproof stuff sack with compression straps that works great for down sleeping bags, take a look at STS eVac Compression Dry Bag or on a lighter version STS eVac Compression Dry Bag UL.

Waterproof stuff sacks are a staple in the list of the most used and practical pieces of outdoor gear. It might seem that such a simple "bag" couldn’t have much room for improvement. However, the opposite is true, and waterproof stuff sacks had a significant upgrade at the beginning of 2023.
The key improvement lies in the change of the sack’s shape. The new version features an oval base, allowing for more practical packing into your backpack. This design helps fill the space in your pack without leaving empty, unused areas. Some hikers had previously complained about dead space in their backpacks when using the older version of the waterproof stuff sacks. This issue should now be resolved.
