I use these shirts for work and I love them. They are really comfortable and don't shrink in the wash. They work really well for transfers, as well. Very happy with these shirts.
There are backpack/convertible totes that are more than quadruple the price that are equally stylish and less functional than this here bag. It goes with everything, holds all that I need it to (laptop, etc), and it's even weatherproof. If you're debating, just get it. You won't be disappointed. Also, I never leave reviews but I was shocked to see there wasn't a load of 5 star reviews for this bag... happy to be the pioneer!
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.
