I always invest in a high quality rain jacket because the cheaply made ones aren't very waterproof. One brand that I know is reliable is Marmot, and REI is selling this men's PreCip rain jacket for only $69.99 in your choice of 10 colors now through 5/29. This jacket is made with the new Marmot NanoPro fabric that is not only waterproof, but also windproof and incredibly breathable. The same jacket is available for women here in your choice of 15 colors for the same price. The jackets come in sizes XS-XL depending on the stock for each color.
