Inside this folder your will find all the Malden Mills Polartec Products.  There are 100, 200, 300, and Windpro.   NOTE, 100 is no longer available.  You will also find Performance, First Layer and Misc high end fleece.  I'm often asked questions like "which is warmest".   It's difficult to answer unless I have all the infor regarding just what type of activity you and your dog will be doing, where you live and what are your outdoor temps.  I often tell my hairless customers...just dress your dog as you would dress yourself.  Would you go out in just a fleece sweater in 32 degree temps...probably not, you would have a layer under and more then likely put on a vest or overcoat.  Your hairless would appreciate the same and if not maybe even more as their "normal" body temps are higher then yours and therefore get cold quicker.  I'm more then happy to help, please provide as much background info you can.    Randi, and the two AHT's...Rosie and Tanner
