2 years ago or so I bought a fanny pack with a bottle holder. “Unfortunately” there were only in earth tone green, brown, beige. Not necessarily the colors I like.

All this time I had planned to sew the bag myself. This weekend was the sewing of the bottle holder. I had to first buy a few things such as thermofoil, rainproof fabric, etc.

Here is the original bag as I found it on Amazon.

Every time I walked around with the bag in the summer, I was annoyed that my drink got warm so quickly.
That’s why I searched the internet for a fabric or foil that would either keep it cold longer or warm in the winter.
I found bubble wrap, which is coated on both sides with aluminum foil and is also used for freezer bags. So that it works even better, I have taken this foil double. I even used it on the striped part.

The bottle holder is slightly larger than the original, because I wanted the bottle is completely in the holder.

The original bottle holder can be attached to the belt so that it does not “wander” while running. I did the same with mine. I even had to buy extra wide Velcro for it.

And here is the finished bottle holder. The bag for this is very elaborate and will take accordingly longer until I have sewn it.
