The Eagle Sled was built for Philadelphia Eagles D-line (and veteran college)coach Pete Jenkins. Offers five of the new Versatile Sled Pads featuring World's patented Double-Action Arms(which may also be used as a Hand-Held Body Pad). Jenkins call it a "1-gap, 2-gap combination pad," which can teach players 1, 2 and combination gap responsibilities. Two of World's Dual Shoulder Pads are included on the reverse side of the Sled. Both sides allow players to practice hitting on the rise, explosion, and full-arm extension. The Eagle Sled is also great for the O-line, Tight Ends, and Running Backs.
