Would buy again

wear this under my suit every autocross season weekend. held up through a full season of washes without the fabric breaking down. pricier than a cotton base layer but that's the FIA rating talking. does what a fire-rated layer should, disappears once you're strapped in.

Good value

switched to this after my cotton undershirt started feeling sketchy under the suit. breathes surprisingly well for a fire-rated layer, doesn't turn into a sauna under the suit. runs a little small, sized up and it fit better. does what a fire-rated layer should, disappears once you're strapped in.
