The story here with the Triumph II is the increased mobility of the thumb. Added ribs and folds give you the best possible feel on the stick with minimal loss of mobility. The Triumph II glove added back hand venting and shorter cuff as well. Check out the Duke Lacrosse Brine Triumph II Gloves.
Basically this is a super protective glove for advanced players who want maximum flexibility and performance with the protection needed to go to the cage.
