A composite material for forming custom fitted orthopedic and other products. The composite material is easily formable when heated to temperatures of about two hundred degrees Fahrenheit for a time of at least six to eight minutes and then is rigid at temperatures of about one hundred thirty degrees. The composite material can be sewn and formed in complex shapes when initially heated to about two hundred degrees. Closure attachments can be secured to the composite material as needed on site rather than at the manufacturing facility. The composite material can be custom fitted to a patient in situ.
