HanesSport Men's Long-Sleeve T-Shirt Pack, Cool DRI Moisture-Wicking Performance T-Shirts, Performance Tee, 2-Pack

How do i know this has upf 50 protection? i don't see that claim on the packaging

Does the shirt smell bad after one wear? I'm planning on using it on a 2-week camping trip in a tropical climate with no opportunity to wash it.

Just bought 4 shirts in lrg. Im 5'9 183lbs will this be a good fit?

I heard polyester can bring out body odor. Anyone had this problem with this shirt?
