All soap and shampoo bars featured on our site are use 100% natural ingredients, and are biodegradable, which makes them perfect for use while camping or backpacking because they are safe to be rinsed into the environment. They easily fit into a carry-on, and are a breeze to take through TSA since they're a solid. They also create a lower carbon footprint than regular shampoo since they're multi-purpose, are highly concentrated (so less is more!), and utilize minimal, non-plastic packaging. Use the filters to the right to find bars that are made for babies & kids, pets, or are anti-itch.
