Sizing is confusing
Your product is good, your customer service is great, your return policy is great. My only problem keeping me from giving a 5 star rating is your sizing. I ordered a 4XL based on your sizing chart ( I wear a 3XL and I have other vest that are 3XL ) the 4XL fit me like a 1XL returned it for a 6XL which I received and it fits me like a 3XL which is good for me because that is my size. Therefore I am confused at your sizing and not sure if I would feel comfortable ordering other products.
