Our tan Tahoe beanie is 100% acrylic. It has a "Stay Salty" Binky Bro Surf Co--Surf|Snow|Skate patch on the front. Sizes are currently available in infant, toddler, Youth/Adult-small, and Adult Large. 
If you are purchasing for an adult please review the product pictures. If you prefer your beanie to sit in the middle of your ears and stand up the Youth/Adult-small is probably the best fit. If you prefer to have more coverage and a slouch look the Adult Large is best.
