Excellent dress shirt for the summertime!
Size: X-Large, Color: Navy Blue, Size: X-Large, Color: Navy Blue
This has rapidly become one of my top shirts to wear during the summertime, and it isn’t even summertime yet! Got this shirt in the other day and this shirt just checks all the boxes for me. It is comfortable in fact that it’s very comfortable. The material is not dry fit but it is not a material that will make you sweat the way cotton would make you sweat.. the fit is spot on, and it just happens to be one of those shirts (we all have shirts like this) where it is one of the go two shirts that you grab when you wanna look nice, yet you wanna be comfortable.
Another thing I like about this shirt is the collar it doesn’t stick out too far and it just seems to fit in place the right way. Some collar on some shirts rest too far outside of your neck and some hug along your neck line, this shirt does neither of the two, it just fits perfectly. The material is very breathable allowing this shirt to be worn in any nice weather climate whether that is warm, hot, or that very sticky humid hot..
Another great thing to point out is I have washed it twice already and it keeps its nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is aAnother great thing to point out is I have washed it twice already and it keeps it’s nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is a steal of a deal, yeah I wish I had a closet full of these shirts with other colors.

Great watch
Color: Green
This watch is two times the price of the he casino watch but it is so much better. The indigo dial lights up completely from all angles. It is easy to read even in 0 light. Much more durable and runs on 1 battery instead of 2 batteries in the Casio. Can’t go wrong with this watch!!!

First watch was defective, Replacement is great
Color: Green
It says indiglo on the watch face but there is no illumination what so ever. Totally useless in the dark. I exchanged it for a new one and it is perfect. Just what I expected. I can't speak to its accuracy yet, but it looks and feels great. The bezel doesn't move if that is important to anyone, but I don't think anyone is taking this scuba diving.

Worth it
Color: Orange
Excellent for the price. The indiglo is highly visible as a backlight. It's simple and no frills. The band is better than I expected. I gave it 4 stars because it's only water resistant to 100m or 10ATM and the adjustment/indiglo button isn't flush with the case. Overall Excellent choice for an outdoors watch.
