Editors Review: The Outpost Canoe is a thermoformed canoe hull and is thinnest on the bottom by it's nature of construction. That being said, price is a major advantage of the adventurer because of this simplicity in construction. Single hull construction allows the water to not get trapped and easily emptied by turning over, sorry no drain plug. High density polyethelene is a great material for all around use. The material flexibility makes this great for rivers with rocks. If you want to know more about thermoforming canoe construction read our canoe buyers guide.
