Flat-Liner™, Maximum Comfort

Flat-Liner ear muffs are designed to maximize comfort.  
FlatLiner Muff, HB-640 Optional storage bag, SGB-30

Maximum Comfort

Elvex Flat-Liner was originally designed to provide flat attenuation for 500 Hz and up, but the market has shown no interest in this concept. That's why we have redesigned this product to offer a medium level of attenuation and absolutely maximum level of comfort. This is how we maximized comfort:
  This earmuff is designed to address the issue of having the right protection, and maximum comfort.
  Low headband force
  Wide ear cushions in order to distribute the force over a larger surface area
  Soft ear cushions with an expanded vinyl for a subtle feel against the skin
  A soft , padded headband
  Steel headband tolerates temperature extremes without losing force
  26 dB NRR from certified U.S. laboratory to ANSI S3.19-1974.
  32 SNR from certified European laboratory to CE EN-352-1
  This earmuff may just have the right attenuation for most noise environments.
