Really like these thicker quarter zips we bought for our business. We were able to use a cricket to iron on customer logos etc. Size wise, the Larges are true Larges, maybe a bit longer than most. Service wise, Jiffy has FAST shipping and has been easy to work with. Will keep recommending them.
Our company does "casual Friday" apparel in a financial institution, with the stipulation that staff wears our logo apparel and nice jeans, etc. These tops are super-popular with everyone and we even had reorder requests!
This is a light weight material that has a professional look. I needed a black and yellow jacket to match the company logo and this fit the bill well. I used HTV vinyl on the front, side and back.
