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, we cut it in pieces to position both vertical and horizontal stretch wherever needed for better fit and function. Instead of using normal straps that have no thermal qualities and are bulky under the waders, we made ours to fit and feel snug while offering the needed stretch. Keeping wading boots in mind, we made the cuffs high and tight. This will prevent bulky ankles and give maximum comfort.
