The Bauer Profile 951 goal mask is an excellent choice for goalies looking for a well priced helmet that can perform at advanced levels of play. The Profile 951 was built using a fiberglass shell reinforced with Kevlar which offers great protection, and also keeps it lightweight. The foam liner is separately attached, meaning you can remove the padding, giving you the ability to clean, fix, or paint the mask. Holes have been placed strategically throughout the helmet, ventilating the mask, keeping the you cool. The difference between the Profile 950 and the 951 is the cage. The Profile 951 uses a Non-Certified cage, legal only for players 18 years of age and older.
