Speaking only for myself, it's more an observation and question than a complaint. I thought it strange that Millar has all the other Big East schools besides DePaul and UConn, as well as most other schools of note across the country.
I have always preferred merch with subtle and understated designs to loud and busy ones, which is why I like the minimalist Millar stuff. I have my share of loud stuff too and it has its place, but I get far more everyday wear out of the understated items.
My wife stole my old school 1/4 zip Husky fleece (probably Antigua or some such) around 20 years ago and she literally wears it almost every single day. It's navy blue and just has the small, old red-tongue Husky logo embroidered on the left chest. I replaced it for myself around 5-10 years ago with a Nike sideline 1/4 zip that has the new Husky logo on the left chest. It's fine and I wear it often (especially to games), but it's more of an athletic item than a piece of normal clothing.
I only have a few Millar items and none of them are branded. I like their pants because they're incredibly comfortable and versatile, but would not want them branded with a UConn logo. The only 1/4 zip I have from them is wool and it's well made and was a good value based on comparable products, and it's also unbranded. I don't think the collegiate stuff comes in wool so I'm interested to see what all justifies the price tag on those 1/4 zips, but I've happy been enough with the quality of their other items that I would check one out when available and see if it's worth it.
