Bear Outdoor Dry Sack/ Waterproof Bag

These come in a variety of sizes and have are incredible for wet/dry hikes and sheltering your gear and food from rain, rivers and floods.

I have 5L, 10L, and 20L sizes which all serve different purposes. The 2L is tiny but great for keeping your wallet and keys dry. While the bigger sizes make great bags for short trips, or liners for your main backpack.
