The answer to this question depends on the type of vest you want to buy and what type of features that it has. Infusing a hydration pack is a great way to add great tasting water to your day and prevent you from having to leave your fishing spot to go and get a drink.
Some vests will have the option to add this while others won’t so it’s important that you check the product description and the bag as well as your infuser to ensure that you will be able to fit it onto your fishing vest.
