1.) Neck Support should be worn with the opening in the front.
2.) If you find the support is too thick in the front or back simply unzip the collar and trim the foam. The foam may be trimmed with an electric knife. Cut approximately 1/8” at a time. If you spray silicone on the blades of the knife it will cut the foam easier.
