Review on MOHEEN Moisture Wicking Performance Men's Outdoor Shirts by Justin Gomez

I bought three of these short sleeve shirts and they fit great. I wear 3XL. When winter came I thought I would order a long sleeve version of the polo and the colors I wanted were out of stock but I was able to order this grey. It arrived today and I liked wearing it with jeans but it fits like a size XL. It's so tight around my chest and waist that I feel like the 3X label is wrong. I don't know what to do, I hate giving things back, I don't like the process but I'm very disappointed in this shirt. I have to lose about 30 pounds to wear it. I thought I found a brand that fits my size really well, but probably not in long sleeve versions? I still wear short sleeve polo shirts but would like some long sleeve polo shirts. If the manufacturer reads this, can you let me know if you have a different cut for long sleeve and short sleeve polo shirts? Disappointed!1
