Jackets that are British Open tested

SOUTHPORT, ENGLAND -- Don't think of a rain jacket as a fashion statement. As the pros who braved the elements Thursday at Birkdale will attest, good foul weather gear is serious equipment and worth investing in. Here are a few things to think about:

1. Waterproof vs. Water resistant
When you get a waterproof jacket it should keep you dry in a steady rain and not allow any water to leak through. The zippers have flaps or seals that prevent water from seeping inside, and the seams inside the jacket will often be sealed as well. What you might be sacrificing is some breathability.

A water resistant top will usually be more breathable, but if you get caught in a long, steady rain you'll get wet. If you are playing in a light drizzle or a light rain, you'll stay fairly dry. On a hot summer day, a water resistant top will help you avoid feeling like a steamed clam.

2. Warranties
If you are looking to invest in a waterproof jacket, look for one that has a warranty. Many, including the tops listed below, promise to keep you dry with normal use for at least two years.

3. Wind resistance
Waterproof jackets should be windproof too, but many water resistant jackets are windproof these days as well. On a chilly day, having a layer that blocks the wind will make you feel a lot warmer.
Here are four rain tops that will keep you dry and comfortable for years to come:
