Choosing Rain Gear can be an expensive proposition.  However, if you are caught in a downpour, or find yourself in an extended rainy period, you will be thankful you have spent the money.  There are 3 basic types of rain gear. Waterproof/Breathable ,Water-Resistant/Breathable,  and Waterproof/Non-Breathable.

Waterproof/Non-Breathable is usually less costly than the others. Generally these products are made with a PVC layer, and being non-breathable they can become very uncomfortable to wear, perspiration and the trapping of excessive body heat can occur on even a chilly day. Beware of those garments that have only a couple of small holes for ventilation.

Water-Resistant/Breathable is just what it says, 'WATER-RESISTANT', this means that in a steady rain they will not keep the water out. The garment will eventually soak up the water and transfer it to the clothing underneath.

Waterproof/Breathable garments are favored by many.  They are more expensive than the other options, but generally are better Vented, and the fabric itself allows body heat to escape while keeping the water out. The fabrics that do this are specially designed and often having identifying names, such as Gor-Tex or Hydroseal, or various other brand name companies with their own branded fabric.  These fabrics do keep water out very well, but after exended wear in downpour conditions can absorb water.  Smoke residue and dirt can also clog their micropours allowing water to wick in to clothing underneath, so it is important to keep these garments clean.

What to buy?  Buy those items that fit your purpose.  Ponchos can be the perfect choice, but if you are hiking they might not be ideal as closer fitting coats and pants.  Look for sealed seams, vents with rain guards, underarm vents or shoulder/backflaps- mesh lining is ideal. Other lining may be composed of special fabrics that wick moisture away from the body. Find a style that is comfortable for you. Shop for sales there are many brands out there.
