I plan the swag at a brewery, so I buy a fair bit of shirts from Jiffy to see if we want that one to make our line up. This was cozy, soft, and perfect for cold weather. There weren't a ton of colors and they didn't have a full mix of sizes so we couldn't use it, but I'm really liking the samples, I wear them under flannel when I do delivery runs. Also note that while the thermal texture is nice for wearing, I don't think you want to screen print it, it would probably tear itself up. And I don't think a patch would work well because the fabric has a touch of stretch to it when you move (not like that weird spandex, it's just the way the thermal is) So if you do a patch, I'd make it small or the thin kind, not the thick ones. I'd pop for embroidery if I was going to customize this. Probably the best way to do it. And I might do the sleeves rather than the chest because there's less flexing there. Overall, 5 for the shirt as far as comfort and buying just for a good value one off, but only 3 for the purpose of customizing it. It's really hard to get the perfect look with four colors and no stock in some sizes.
