Ryan,
When we picked up this hat (youth Joker) at the Brandywine Arts Festival in September, it was 90 degrees outside, but my son wouldn’t take the hat off for the whole day!  He finally got to wear it in appropriately cold weather during a trip to Connecticut a few weeks ago (shown in the pic accessorized with daddy's sunglasses) and he's been wearing it ever since it got cold here. Everyone that sees it, loves it. But I’m sure you hear that all the time!
Thanks for a great hat that he actually LIKES to wear!

About the fleece
Most of my fleece is made by Malden Mills here in the USA.  It is the best fleece available that does not pill or degrade like cheaper imported fabrics.  You can learn more by visiting Polartec®

Technical Highlights

Provides warmth without the weight and bulk of traditional insulating fabrics

Highly breathable to provide comfort in all activities; does not restrict the movement of moisture vapor

Dries quickly to minimize heat loss

Durable; will outlast other imported fleece fabrics. It does not pill up like the cheep imitations.  Plus it is made in the USA!

Machine washable.  Please turn hats with eyes inside out to protect them.

Versatile; appropriate for a broad range of activities

Much of the fleece is made from recycled soda pop bottles!

I work with different thicknesses which provide different levels of insulation for outdoor activities. 

100 weight fabrics are the lightest and are excellent for a warm first layer, for heavy aerobic activity such as running or for  warmer climates.

200 weight is about twice as thick as 100wt.  It is the normal weight that jackets are made of.  It provides outstanding warmth and versatility.

300 weight is the thickest.  It provides the most warmth.  It normally is too thick for most hats

Berber  is a special fleece that is nubbly on the outside with a smooth face for the inside.   Many folks enjoy the texture of this fabric.  It is not as wind resistant as regular fleece.
