Used by the Women's Silver and Bronzed Medalist of the USA TEAM and as Olympians in Athens!Used by Tye Harvey Premiere International 19' jumper USA TEAM Alternate to Athens!Essx poles were used last year to set many personal records across the nation as well as internationally by both male and female vaulters. Its unique design is unlike any other vaulting pole on the market today. The secret is a stiffer butt concept, that reduces quotlow pole penetrationquot in the box area and creates excellent quotbending over actionquot in the upper areas of the pole. Results higher grips, better form, and higher heights!Helical Carbon ESSXIMPORTANT We use an exclusive quotQuadra Helical Windquot for increased Carbon Hoop. This increased strength allows the vaulter power while timing with the pole not rushed for the shortest time sector in the double pendulum of the vault. ESSX is designed and tested by the Xlogic Team to be superior in overall pole weight and balance. All poles from 3.75M on up are basically custom poles and each pole includes the actual flex test photo packed in its very own PVC POLE CASE. You get XLOGIC technology with each and every ESSX pole
