Made with spandex and soft fleece, the half stretch fleece vest has a stretchable bottom for better fitting while providing warmth and comfort. The soft fleece is made with 95% polyester and is the same fabric used in making baby ear-warmers and bedsheets. That should tell you how cozy it is. It is widely used in the garment industry, here's why:

 

1. Strong, durable, yet lightweight.
2. Retains heat and keeps warmth.
3. Retains shape.
4. Wrinkle-resistant.
