Here is the inside. In the pic I have my wallet, a set of keys, sunglasses and iPhone 6. There is plenty of extra room so a 6 Plus should fit just fine. It also included a detachable strap with buckle so you can take it off the bike with you and wear it over your shoulder or around your waist. Or, as we Americans call it, a "Fannie pack".
