UST Essx, simply referred to as Essx is a brand of pole vaulting poles used by athletes for the competition. Essx is currently owned by UST Mamiya, a golf club manufacturer.[1][2][3] Started in the mid 1990s by Bruce Caldwell, Essx gained publicity as a major pole vaulting brand when their sponsored athlete Sam Kendricks made the list of the world’s best pole vaulters.[4]
Based in Fort Worth, Texas, Essx manufactures several vaulting poles and pole vault accessories.[5] Their main line of pole, the Essx Recoil Advanced, has undergone several design changes over the past decade. As of 2019, top collegiate athletes have switched to vaulting on Essx poles.[citation needed]
