I get a lot of questions from people who are wondering if my fleece coats are water-repellent or water-proof.  It made me wonder about fleece in general, so I looked it up. I found a helpful little blurb on www.eHow.com:

 "There are a number of significant advantages to using fleece fabric. It is easy to sew and launders well. It is machine washable and dries quickly because of its construction and is therefore also water repellent. For this reason, it also wicks moisture away from the body, making it appealing for outdoor and athletic wear. The fabric itself is lightweight, soft, very comfortable and extremely warm. It is available in many colors, patterns and prints. Fleece is an excellent alternative fabric for anyone allergic to wool. And it may be considered earth friendly since some fleece fabrics are made from recycled plastic bottles."

So, there is your answer. Though not waterproof, I guess all "fleece" is water repellent to a degree.  I know that my standard poodle's coat keeps her nice and dry in a drizzle or light snow, and it also dries pretty quickly after we get home.  I have not tested it in a downpour because frankly, I don't want to be out walking in a downpour, and neither does she.  Anyway, my waterproof nylon raincoats are coming soon, so if you do like to (or need to) walk your dog in a heavy rain, check them out!
