Wingnut is dedicated to providing the most innovative cycling and adventure racing products. Our hydration packs are hand built in the USA from light, waterproof sailcloth fabrics, and feature the Lowrider System for a custom fit and better balance. We are constantly upgrading materials and designs based on your input. We also like to push boundaries and are currently involved in development of mobile solar powered trauma/medical stations. This solar program has since evolved into ecopioneer.com and takes up most of our marketing efforts so please spread the word.
