MIG100 includes three panels in back for a tailored, professional, more comfortable look and feel. 

MIG WEAR Jacket uses only 9.5 oz/sq yd, 100% FR treated cotton sateen fabric that is independently certified to meet ASTM F1506-94, before and after 50 industrial washings.

Jacket also meets EN533, EN531, and EN470.  Non-reflective snaps at sleeves help prevent sparks from entering up sleeves and in front for a safe and secure closure. And, you'll find a handy inside lapel pocket, for small items. All this and lower prices too.
