Product Description The Shefford Heat Panel Vest delivers lightweight, water-repellent warmth with a shot of exciting technology.

If I ever wear one of these fleece/puffy vest at the office, especially at an edgy place with no dress code, I’m not going to wear anything underneath, just like pac so I can make people feel uncomfortable.
