Durable compression stuff sack that helps reduce the volume of your sleeping bag, down jacket or clothing, while also protecting it against water and moisture. It is constructed from durable 70D nylon. It is suitable for bikepacking and other activities where you appreciate greater durability.
This could 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 durable and strong 70D nylon with a PU coating. The bottom is made of 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 10 000 mm. It has 4 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 lighter but less durable material – STS eVac Compression Dry Bag UL.
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.
