Trading in the original Elevation high altitude oxygen training mask for the lighter, more compact, and generally sexier 2.0 version is kind of the same as Justin Timberlake trading in Cameron Diaz for Jessica Biel: UPGRADE! The Elevation 2.0 provides the same pulmonary resistance training as its predecessor, but instead of covering wearers' entire face such that they look like they're in the midst of a full-on gas raid, it covers only the nose and mouth such that they just look like they have a touch of the SARS virus.
At 9.6 ounces, the updated Elevation training mask also weighs less half of the original, and with a soft, neoprene-covered rubber face shell, should prove to be more comfortable to wear. Even bigger bonus: it is designed to be clothed in personalized sleeves. Namely a frikkin' Bane sleeve!
Elevation Training Masks endeavor to help regulate breathing, increase lung stamina, improve lung capacity, and up oxygen efficiency. User reviews are generally positive, though many point out the conditions Elevation masks create do not truly replicate those found at high altitudes. That is, while regular use will better the function and efficiency of muscles that normally do not receive much attention during workouts (e.g., the intercostals that stretch alongside and separate each rib), the masks will not alter a person's actual cellular physiology in the way living at altitude can.
