We're happy to confirm that the Iota will have carrying bag! Several of you have observed that carrying bags would allow users to take full advantage of the small size of the Iota. Since we've exceeded our funding goal, we expect to be able to include a bag at launch, whereas previously it was not a sure thing. The bag will be made of a high quality, durable material and have a place for the charger, and an extra battery.
In the future we'll likely sell the carrying bag separately to keep the price down on the basic Iota package, since there will probably be some people who don't need a bag. But for our backers a carrying bag will be included with each Kickstarter Iota unit.
