The FenderBag Idea

FenderBag developed out of Doug's do-it-yourself need for custom outdoor gear. Kathleen, long-time friend and partner, along with other local Steamboat Co., residents identified Doug's early FenderBag prototypes as a really "great product". This recognition inspired Doug to submit patent filings and begin to take steps towards the development of FenderBag as a company.
