Big 12 Conference Big & Tall Apparel — 3XL–6XL, XLT–5XLT

Big 12 gear in big and tall sizes is hard to find in regular team shops, where most conference apparel stops at 2XL. This page is the hub for officially licensed Big 12 T-shirts, sweatshirts, hoodies, and jackets built for bigger and taller fans — sizes S, M, L, XL, 2XL, 3XL, 4XL, 5XL, and 6XL, plus tall sizes XLT, 2XLT, 3XLT, 4XLT, and 5XLT. Whichever of the 16 schools you root for, if you wear a 4XL or a 3XLT, this is the page that treats your size as the point, not the exception.

The Big 12, All Sixteen Schools

The Big 12 nearly died twice — picked apart in the realignment waves of the early 2010s, then raided again in 2021 — and came back bigger than ever. Since 2024 the league runs sixteen schools across ten states and three time zones: Arizona, Arizona State, Baylor, BYU, Cincinnati, Colorado, Houston, Iowa State, Kansas, Kansas State, Oklahoma State, TCU, Texas Tech, UCF, Utah, and West Virginia. It is the most geographically chaotic conference in America, and the basketball might be the best in the country. Every one of those schools has big and tall fans, and every one of them deserves gear that fits.

Two member pages on this site are fully rebuilt and stocked in the complete size run:

• Kansas State Wildcats tees and hoodies — EMAW, in purple that fits
• Oklahoma State Cowboys big and tall tees — Orange Power, in orange that fits

Every Size, Listed One by One

People search for their size, not for “extended sizes” — so here is the full run, size by size:

• S, M, L, XL, 2XL — the standard run, stocked everywhere. If these fit you, every Big 12 page we run has options.
• 3XL — where most team shops quietly stop. On this page, 3XL is just the start of the big and tall range.
• 4XL — a genuinely hard size to find in conference gear; the apparel linked here stocks 4XL as a rule.
• 5XL — the size big fans usually have to special-order. Big 12 5XL tees and hoodies are a core part of this collection.
• 6XL — the top of the big range and the hardest size to find anywhere. If you wear 6XL, start here.
• XLT — tall, not just big: extra body length for tall frames without the extra width of the next size up.
• 2XLT — the tall counterpart to 2XL, for tall fans who need length more than width.
• 3XLT — where big meets tall; one of the most searched-for and least-stocked sizes in fan apparel.
• 4XLT — big and tall together, with the hem length tall men actually need.
• 5XLT — the top of the tall range. Big 12 5XLT gear exists; it is linked from this page.

Not sure which one is yours? Our size chart has the chest and length measurements for every size above, and the FAQ page covers shipping and returns. A conference-wide fit note: this league plays November football in Ames, Manhattan, Morgantown, and Salt Lake City — if your school is a cold-weather stop, take the hoodie or jacket in the larger of your two sizes so it layers.
