Go up one size. It is the most comfortable choice if you are already unsure.
QUILLMORE size guide
Choose a size without guessing.
A heated garment should fit close enough to the body for the warmth to be felt clearly, but never so tightly that it restricts the shoulders, chest or movement.
Before choosing
The heat is felt better when the garment sits close to the upper body.
Allow a little extra room for movement, especially in jackets and down jackets with sleeves.
Avoid too loose a fit: the air between the garment and your body reduces the feeling of warmth.
By model
