Held up all season

switched to this after my cotton undershirt started feeling sketchy under the suit. fits snug without being restrictive, good base layer for a multi-layer suit. runs a little small, sized up and it fit better. recommend as part of a full nomex setup.

No complaints

Picked this up as a base layer for lemons. held up through a full season of washes without the fabric breaking down. runs a little small, sized up and it fit better. does what a fire-rated layer should, disappears once you're strapped in.

Does the job

Picked this up as a base layer for a full season of club events. breathes surprisingly well for a fire-rated layer, doesn't turn into a sauna under the suit. recommend as part of a full nomex setup.
