Ultralight waterproof compression stuff sack that helps you reduce the volume of your sleeping bag or clothing while protecting it from water and moisture. It is constructed from lightweight Ultra-Sil™ 30D nylon.
This might come in handy for you.

A practical accessory for sleeping bags or clothing that you want to keep dry at all times (sleeping clothes or down jacket).
The body of the stuff sack is made of lightweight and durable Ultra-Sil™ 30D CORDURA® material. The bottom is made of a breathable eVent membrane, which allows air to escape while preventing water from entering. Taped seams emphasize the waterproofness and strength of the bag. The water column of the stuff sack is more than 2000 mm. It has 3 compression straps on the sides.
After inserting the equipment, roll the closure at least three times, buckle the strap, put on the “cap,” and you can compress.
We offer additional compression waterproof stuff sacks made of more durable but heavier material – STS eVac Compression Dry Bag.
If you don't want compression straps (extra grams), check out the waterproof stuff sacks without compression straps. However, you can partially compress them by squeezing and blowing out the air.
