The simple answer is it is too big for you. Eat more burgers and wear lots of clothes, or replace it
With the pictures of your bottle pouch your back must be smashed!
The velcro on the vest MOLLE is irrelevant, this can still be weaved or gives you the option of putting on name panels etc instead.
The velcro on the pouch will have little effect. You can attempt to tighten the strap to the vest and press the velco together, but it is still always going to jump loose with a little movement.
You can attempt to enhance the velco by adding some. e.g. go to your local haberdashery/fabric shop and get some sticky backed velcro:
1)Take 2 strips of spikey velcro, stick them back to back. Put this on your vests horizontal.
2)Take a strip of spikey and a strip of soft, stick them back to back. Put this along the verticals
The extra velcro will give more hold, but depending on how active you are this may or may not stop it bouncing on the vest & your back.
The real answer realy is you don't appear to have the right type of bottle pouch.
It looks to me to be the type of fitting that should have a large velcro flap on the vest. You open the flap, velcro in the vertical straps, close the flap press the pouch, and finaly button the strap to the pouch.
With a large velcro area this then becomes solid.
There was a video on YouTube a few years ago going through this. I cannot remember the name of the design, or find this to illustrate.
