Yup, wasn't gonna capitalize the com.
And yeah, there's a really straightforward shirt without the softer material, and without anything on the back, for people who just want a simple shirt, that'll cost significantly less. I've got a few of the softer ones from Vistaprint and I've really liked them, though I don't know if you're referring to softer shirts in general, as opposed to this site in particular.
Oh, also, just to complicate things further, they do have Men's and Women's models, though the Men's are more like unisex. I'm creating the designs by those on default since they should be fine on anyone, but I can recreate any of them on women's on request, and might do a couple of the basic ones that way preemptively.
