I am 'scratching an itch' and developing a new running armband product myself as I've been unsatisfied with armbands I've tried. I like some of the armbands out there and have bought previously Nike, Nathan etc but they're all strap based with plastic windows.
My dream armband is comfortable, is more sleeve than strap and doesn't bother with plastic windows but focuses on sweat control and function. I came up with a design and made a prototype - would anyone be interested in this type of product? I am trying to figure out if this is something people want.
The first prototype is can be seen below:
Would really appreciate your thoughts.
