I especially like the v-neck neck hole of this rashguard. It's not so narrow unlike the round neck hole of my other rashguards which mostly are narrow. I can get quite uncomfortable wearing a narrow round neck rashguard. However, it's different with this Virus rashguard. The v-neck neck hole does not make me feel uncomfortable.
As for the fit, if you follow the size chart, the rashguard will be a snug fit. Choose one size up if you prefer a looser fit.
