Colorado Box Lacrosse League

 3d Lacrosse is excited to announce our partnership with the Colorado Mammoth for the Colorado Box Lacrosse League. Box lacrosse is quickly becoming recognized as the most effective way to develop the skills of any lacrosse player.

3d Lacrosse integrates the “Box/Field Hybrid™" Development System for all of our programs and this program will take the "Box" element of your game to the next level. The training will be run by the Colorado Mammoth and 3d Lacrosse’s experienced box lacrosse coaching staff. Box lacrosse skills and techniques such as high level stick handling, finishing, faking, feeding, physical dodging, two man game, picks and screens, and how to play against all of these skills defensively will be the focus of our program.

The Colorado Box Lacrosse League will consist of box lacrosse practices and games over a seven to ten week period.
