Great Shirt, Awkward Shoulders
Color: Light Grey, Size: X-Large
I want to start off by saying, I really, really like this shirt. The fabric is spot on: soft, comfortable, not too thick, not too thin. Honestly, it feels like it was made by someone who understands the Goldilocks principle of clothing. So why only 4 stars instead of 5? The shoulders. I ordered my usual XL, and while the rest of the shirt fit great, the shoulders were so tight I felt like I should audition for the role of the Hulk. I exchanged it for an XXL, and now the shoulders fit perfectly… but the rest of the shirt feels like it’s training me for a parachute jump. If it weren’t for that one sizing quirk, I’d swear off buying any other shirt ever again.

Quality for price
Color: Steel Blue, Size: 3X-Large
Beautiful color, great fit! Has a nice feel to it worth investing in more colors🙂slightly wrinkled but an iron or steam will probably take those out, has a softer feel to the fabric
