Maxit makes tremendous quality products. Long before under armour they supplied the NFL with all of their cold weather gear. Not sure if they still do. In any case I now live in Austin but when I was doing graduate work on the East Coast this was by far my most useful and essential piece of winter wear.

It is a tube of polypropelene material that Maxit uses for almost all of their products with some lycra thrown in I believe. You can wear it as a neck warmer but it is stretchy enough to then pull up over your head for a complete head warmer. It is so stretchy that it can also be pulled up under your chin for a balaclava. You can also wear it as a thick headband.

I was at an REI and I saw a similar product with 'rabbit fur'. That one was way bulkier and less stretchy. Maxit's material is highly breathable yet also blocks wind right away. PERFECT for winter activties as you heat up and sweat the sweat is going to be wisked away. If you live in a part of the country that has a winter buy this. If you are an outdoor athelete in a wintery part of the country buy this right now. You will thank me. It is one of my favorite products of all time.
