I tried with an Arista 7050sx, attached are the pictures and the link on Thomann (not an affiliate link (unfortunately ;) ) https://www.thomann.de/de/gravity_bg_wbls_331.htm
The price tag lower than 40€ with shipping is really good for me.
Two things that could be nicer :
- a shoulder strap
- might need to add some protection at the bottom of the bag if you put your ports down

And here is the link to the manufacturer of the bag :
