March Madness has arrived and the men’s NCAA Division I basketball tournament bracket is set with the First Four games beginning on Tuesday and Wednesday. While college athletes will be competing on the hardwood, apparel brands will be competing for exposure and hoping the teams they sponsor make deep runs in the tournament.

Four athletic brands will have teams they sponsor participating in this year’s NCAA tournament: Nike, Jordan (which is a brand within Nike), Adidas and Under Armour. Of the 68 teams in this year’s tournament field, Nike sponsors 36 while another four wear Jordan, Adidas sponsors 18, and Under Armour 10.

Here’s a look at which apparel brands are sponsoring the teams that may make or break your bracket this year.

Oregon-headquartered apparel giant Nike leads the way with 36 teams in this year’s NCAA tournament field with a number of perennial favorites. The lineup includes a pair of No. 1 seeds, the Alabama Crimson Tide and Purdue Boilermakers, and a trio of No. 2 seeds — the Arizona Wildcats, Marquette Golden Eagles and Texas Longhorns. 

All four of the tournament’s No. 3 seeds — the Baylor Bears, Gonzaga Bulldogs, Kansas State Wildcats, and the Xavier Musketeers — are Nike-branded programs. They’re joined by three of the No. 4 seeds with the Tennessee Volunteers, UConn Huskies and Virginia Cavaliers in the ranks, plus the fifth-seeded Duke Blue Devils.
