Originally, the design was a ribbed knit material that was inserted at the collar and stitched into place. It served two main purposes: Like the ribbing at the sleeves and at the hem, the ribbed insert allowed the wearer to more easily don the garment without it losing shape. As the wearer would get their head through the neck of the sweatshirt, the V-insert would stretch to accommodate. The elasticity of the ribbing could stretch as needed without losing integrity.

The second reason is that it helped to absorb sweat. If you’ve seen someone sweat through a crewneck, you’ll know that the chest is a major point of perspiration. Though, the V-insert could only take so much.

Neat
