Training Mask 2.0 has been a work in progress for over 2 years. We have asked our customers of Training Mask 1.0 to give us their feedback and what they would want to see in 2.0. With great feedback from test marketing and direct responses we have made Training Mask 2.0 smaller, lighter and more comfortable. Training Mask 2.0 gives the end user a redesigned look and feel along with the resistance levels that they desire.
