Do you Sue Patrick?
When you're in Austin, the store is at the corner of Burnet Road and North Loop.

I never go to Academy for Texas apparel.
The availability for Texas gear has gotten worse when the Rooster Andrews stores all closed and fucking Fanatics.com (and the hundreds of sites pulling from the exact same inventory) gets 50 or something of each size, and that number is all they usually sell.
When you do actually find good quality/design amongst all of Fanatics' junk quality, once it goes out of stock, it hardly EVER is restocked.
Fanatics has DESTROYED the availability of fan apparel.
The ones I look at are the Co-Op, Sue Patrick, maybe you get lucky on ebay or the other sites where athletes sell their stuff, or luck-out at some non-Fanatics-linked online store like Rally House.
The UT Golf Shop seems great, but as I've trolled them, they only carry shirts and polos for narrow-shouldered tiny people (maximum 2XL sizes), and I was a thin teenager with shoulders that required size 3XL shirts in high school. How hilarious none of their shirts would fit most of the Texas Longhorns football team! Lulz.
