Not as advertised, but I like it! This run runs small and not the blend stated.
Size: 4X-Large, Color: Sky Blue
I rely on your reviews a lot, so I am paying it forward here. I needed a summery, lightweight linen type shirt with long sleeves because I'm an old, fat guy and I'm getting those ugly, purple bruises on my arms (if you're under 65, just wait ;). I just got my shirt today. I read the reviews and everybody said the quality, sizing and the material were all over the board and mine is no different. The label on mine says 60% cotton, 30% viscose and 10% linen. That's a far cry from the 70% Rayon and 30% Linen as stated. However, this material is very light and smooth and has a lot of stretch. The label can't be correct for the material to have this much stretch, but I like it. It doesn't look anything like the picture either. It has a sort of linen like look, but more of a chambray weave look I would say. And it smells oddly nice, too. I'm sure whatever the smell is will go away after washing, but for now, it's a nice, pleasant, new shirt smell. Must be the Viscose or whatever is in this shirt. It definitely has at least 2% Lycra to be able to stretch like this. Also, the sizing is way off. For reference, I am 5'6" and 270 with a 52" waist (I told you, old, short and fat :). Many of the reviewers said it ran small, so I ordered up to a 4x and it fits just about perfectly for me. I normally wear a 3x and in some shirts that's too big. This is loose enough but not blousey and most importantly, covers my big belly nicely. The stretch in the fabric is a bonus. So I guessed right with the 4x. However, read the reviews and you will see that the sizing appears to be all over the board. Finally, the pocket is oddly small. It is fine for my purposes and I absolutely need a pocket to put my sunglasses in and other various little things, but at least in my version, beware that the pocket is oddly small. I think I got lucky with my order and got what I wanted by default. I will have to be careful washing it, or it might shrink too much (there's no telling what this fabric really is). It is also fairly wrinkled out of the package, but being the cotton/viscose blend that it says it is, it should iron out nicely and not wrinkle with wearing. We shall see. I'm impressed with the silky feeling and light weight of this shirt and although it doesn't really look like a linen shirt, it looks casual enough for me to fit the bill. I will be wearing it with the sleeves rolled up anyway, as I just needed something that looks casually sharp and can cover the ugly bruises on my forearms. As you can tell if you read through the reviews, what you might get seems to be somewhat of a crap shoot, but I like mine, so good luck!

It’s nice
Size: X-Large, Color: Sky Blue
This men’s long sleeve linen shirt is lightweight and breathable, which makes it comfortable for warmer weather. The fit is okay, but it doesn’t hold its shape very well and wrinkles easily, which can make it look a bit sloppy. The material feels a little thin, and while it’s casual and easy to wear, it doesn’t have the high-quality feel I was hoping for. Overall, it’s fine for relaxed occasions, but not a standout piece.

Sizes are not standard and color is not accurate per the photos
It did not fit well. The size is not true to the standard and runs larher. Also the color is more burgundy online but the actual fabric is more like a bright tomato red.. color mismatch was the biggest disappointment.
