Nice fall shirt
The material on this is great. Its soft and smooth. The fit is nice around the chest and stomach, although the sleeves seem a bit too long for me (I'm 5'9 and ordered the large). Its not very thick, so it's a nice early fall, late spring shirt. The only thing I don't like is that the fabric retains wrinkles. If this isn't hung up while warm, it will hold on to wrinkles

Stylish, comfortable long‑sleeve polo
Size: X-Large, Color: Royal Blue, Size: X-Large, Color: Royal Blue
I recently tried out this Lexiart long‑sleeve polo and was pleasantly surprised by how well it balances style and everyday wear. The textured knit gives it enough visual interest (so it doesn’t feel like just another plain jersey shirt), and the slim‑fit design helped create a clean silhouette without being overly tight. The collar and button‑placket feel more polished than a typical tee, which makes it easy to dress up a bit for smart‑casual settings. The fabric is comfortable and breathable enough to wear indoors or layered under a jacket. The length and fit were generally good — the sleeves hit just right and the body length worked for casual wear.

Nice heavy duty long sleeve shirt
good looking and good fitting long sleeve shirt. I didn't notice the flag on the sleeve until I unpacked it. Nice touch. Color is true. Material is indeed stretchy. I cannot determine the fabric blend but it is comfortable. The care instructions are included on a card, not on a tag, not be sure to pay attention to it. I am 5'10' and 235, the 2X fits me well.
