Polo/shirt for wearing under vest

I'm starting a new job next week where I will wear a safelife external vest.

I'm looking for a good polo shirt to wear under it.

I like this: https://www.511tactical.com/ss-pdu-rapid-shirt.html?sku=844802272360&country=us&utm_source=google&utm_medium=cpc&utm_campaign=G_Shopping_Brand&gad_source=1&gbraid=0AAAAAD4yJClB66sqBIJRsRb1bRITVCsqX&gclid=EAIaIQobChMIgub38I2FjAMVNEhHAR0C8SUvEAQYAyABEgJbCvD_BwE

Any recommendations?
