Bassn81, Don't even play with them, go straight to Quilomene! I have one and will never buy anything else. Go to www.quilomene.net/vest.htm and have a look. Call Steve, he makes a great product. I use my 100oz bladder most of the time. And I have a 130oz I can put in if it is warm and I and the dogs need it.
