FR Layering is a great way to stay cool and comfortable while achieving the necessary arc protection levels.

Also, recent changes in the NESC and
NFPA 70E have made FR layering more
popular than ever.

Riverside has layering data for most of
our popular FR garments. This data is
subject to change, but this web page will
be maintained with current data.

Here's a 2012 article on Layering that Riverside
wrote for Incident Prevention magazine:
