Forager Vest Sizing
Although the product is very well made, the sizing runs small. I purchased an XXL and could barely zip it up over just a T-shirt. I gave it to a friend's teenage son. I think when the only size is S,M,L,XL or XXL there should be a numerical size accompanying the letter size.
Many products manufactured overseas, especially in Asia, tend to run small.
