Cheap insurance

Picked this up as a base layer for hpde days. noticeably cooler than the cotton undershirt I used to wear, worth the upgrade. does what a fire-rated layer should, disappears once you're strapped in.

Good entry-level gear

Wear this under my suit every track days weekend. fits snug without being restrictive, good base layer for a multi-layer suit. pricier than a cotton base layer but that's the FIA rating talking. good base layer, would buy again.
