FILA Men's Tech Vest

These are nice vests. I bought one in black and liked it so much I went back and bought one in grey. I also have a Columbia vest, a 32° packable down vest and an Orvis down vest, but I like to wear this vest if I want a different look, just a bit nicer/dressier vibe. Add this vest to a casual shirt and jeans and, IMO, it steps your whole look up a notch. These are well made with good craftsmanship and a great value at these prices!

Buuuuuuuut… What makes this a “Tech” vest?
