The Comprehensive water sports Kit is ideal for outdoor guides or as a group kit for multi-day adventures. All of the components are protected and organized inside of clear resealable bags. Header cards are included in each bag to easily identify the contents and keep track of what you use. The rugged roll-down closure dry bag will keep everything waterproof. Exceeds recommended first aid kit requirements of the National Park Service for river trips on the Colorado River thru the Grand Canyon.
