Flexible (or at least not fragile) solar panels?

Question

Batteries

I love photography and can walk in the sun for days with a photo backpack. Of course, the idea arose to hang a backpack with solar cells and thus charge batteries for a camera / flash / phone, etc. The problem is that solar cells are fragile and break quickly on a soft backpack. Of course, you can take many small elements and connect them in series. But! Suddenly there are flexible elements? Something like a metallized film, for example ... Or a fabric with special threads?
