A:AnswerThese are the Fitbit accessories for the Alta. My wife had a band chewed up so I looked around and heard that there were issues with some of the aftermarket bands fitting. This one was seamless and works just like the original that came in the box. Hope this helps!!!
A:AnswerYes, they do make an XL band for the Alta, however it is (currently) only available in black, and can only be purchased from the Fitbit website.
