This shirt really does strike a nice balance between performance, comfort, and being passable as street clothing for your post-adventure beer in town. Like I said, it lives up to the "All Day T" name.
Sizing: I ordered a large. I found it slightly bigger than I wanted it to fit and in hindsight, probably would order a medium. Sleeves were a little longer than I’d like and it hung below my belt line. To be fair, I like athletic clothing to fit tighter than looser if I have to choose one end of the spectrum. Especially because this fabric is so light and stretches a decent amount, I wouldn't mind a tighter fit. All that said, the size definitely hasn't made me like the shirt any less.
Color: I ordered the "blueprint" and definitely is true to the image above.
Performance: I've worn it to the climbing gym and on runs and most recently on a sunrise hike to Half Dome. Great for climbing gym, not awesome for running (that is 100% due to the sizing though, like I mentioned above. If I had it in a medium, I imagine it would be my favorite running shirt), and mostly ideal for a long hike like Half Dome. Unfortunately, for this particular sunrise hike it wasn't ideal because on the Mist Trail...well it got pretty damn misty and since there was no sun to dry the shirt on the rest of the hike, I stayed pretty damp and cool until the sun came up. I wasn't wearing a waterproof layer, so I'd say that's more on me than the shirt. But good to know that it doesn't dry super well without some sun/heat. When the sun did come out though, it dried up nicely and I wore it the rest of the day chillin in the Valley and on the ride home and was very comfortable. Like I said, lives up to the "All Day" name.
