Get it!
Size: 10-11, Color: Blue Plaid
Another must buy on my list! Color, size and length were all good. I was a bit surprised as to the thickness of the vest, not heavy, but well made. Definitely value for money!

Great vest
Size: 12, Color: Black
Great vest. I love the slim fit. It looks very nice on my son, not baggy or boxy looking like some vest. My son has used it for several occasions including a wake, a Beta Club induction, awards day, and soon his graduation celebration at church. The quality and material are good. Definitely worth what I paid.
