True to size, but the sleeves are too long for me. Although good quality. I hope Columbia releases a similar t-shirt with 7/10 and 9/10 sleeve options (just like Uniqlo).
Pros
This was bought for my husband, size XXL is correct. He loves the fit and the look of the shirt. He is 6'3", 240 lbs.
Cons
The shirt may have a strong chemical odor when first opened.
