This dry sack is one of the most used camping gear I have. I've used it countless times as a stuff sack for clothes, sleeping gear, and even a hang bag for food. It's incredibly easy to use as you can squeeze the air after it's been closed. That simple mechanism is incredibly useful, especially after a long day of hiking. I've also used this as a bikepacking bag as the straps allowed me to easily strap it onto my bicycle handlebar. The waterproofing also ensured that I didn't have to worry about its content regardless of weather. Spend the extra to get this dry bag.
