All nylon bags shed water to some extent and even waterproof StaDry will not keep wet clubs from allowing water inside nor will they stop rain from finding a way in when opening the club cover. Leather bags, like shoes will absorb water and need proper care and drying after a rain. Hope you find the one that best suits your needs.

My LinksLegend, older version (Linkmaster) did well in a downpour.. No issues!

My Linksmaster holds up great in the rain but is not as good as a StaDry....

I’ve found that nearly all Titleist golf bags constructed of nylon have decent water resistance. The material can withstand light or intermittent rain. The Linksmaster bags are even better in damp conditions as their synthetic leather really repels water. The issue of water resistance usually comes down to the zippers. Waterproof zippers exist, but you typically only find them in high-end outdoor gear. They are typically very stiff and require effort to open and close.

I had several Titlist Bags in the past , they all had decent water resistance.

Have several titleist bags from over the years. The hoofer is also a good alternative

A rare one that doesn’t seem to be available outside of Europe is the tour premium cart staydry, like this one:

Although the pictures are never right as the actual bag doesn’t have the piping, this is my current bag, it’s like the midsize tour bag, except with 15 way top, waterproof lightweight hood, less pockets, very large insulated pocket and of course waterproof.
