This is my go-to shirt for range days in the summer time. The shirt is about as comfortable as it can be for a long sleeve in the heat and still protect your arms and neck from the sun. It has a somewhat tight/athletic fit which concerned me because I train from concealment. However, between the stretch of the fabric and the break away snaps, clearing my AIWB holster is fairly easy and consistent. The fabric is very thin so printing can be an issue if you need to be worried about that. It makes a great general outdoors/camping shirt too, just don't get too close to the fire because a stray ember will put a hole in the fabric very easily (ask me how I know).
