“Naviti Hydration Waist Pack”

“I primarily use this for extended running treks. It is great for carrying everything needed in terms of hydration and nutrition when traveling fast and light. It fits very comfortably on the waist/back, and allows for sufficient refills on a point-to-point course. The dual bottle carriage allows for water as well as sports drink as choice during competition. One setback of it is that it has a wide back that can be quite stifling in the heat during extended runs (50K, 50-milers), making the lower back feel overheated. Otherwise, if that doesn't bother one, it is a well-made system that provides a carrying system for all of one's fluid and nutritional needs during extended hikes and endurance competitions.”
