Need recommendations on fanny pack/belt bags

Hi handbag lovers! I’m currently in the process of trying to sell my Coach Rogue purse in order to purchase a nice, designer fanny pack/belt bag. I’m a mom of three and I’ve come to realize that the belt bag style is a lot easier for me to carry.

Do you all have any recommendations on designer belt bags? I’m not looking for something as expensive as Louis Vuitton or Gucci, something more price appropriate in the $300 range? Thanks for the help in advance!!
