The Nalle overall is the best value mid-layer fleece available. Its simple design hides a technical item of clothing with a complicated cut. As standard fleece stretches in only one way, Vision cut it in pieces to position both vertical and horizontal stretch wherever neededfor better fit and function. Instead of using normal straps that have no thermal qualities and are bulky under the waders, Vision made theirs to fit and feel snug while offering the needed stretch. Keeping wading shoes in mind, they also made the cuffs high and tight. This will prevent bulky ankles and give maximum comfort.
