The shirts (I bought two of the same shirt) are high quality, as are all products from Mike's various dog-centric companies. I've been a Team Dog member, my personal dog is on Team Dog Elite Blend dog food, I have multiple Trikos and Team Dog hats from Mike, and now the shirts. While these shirts are well made, they run a bit small in the sleeves... i.e, the sleeves are VERY tight. Now, I do still workout and I have bigger arms than most of my 60-year-old buddies, but I'm just 'fit,' I'm not a bodybuilder, and these shirts are very tight in the sleeves on me. I'm 6'1" 190lbs and bought the LARGE size, and while I think that's the correct size for me in terms of shirt length and shoulder width (the shirts fit me perfectly in those two areas), the sleeves look and feel like they're somewhere between a medium and a large. Anyway, I do like the shirts, and the quality of material and workmanship are outstanding, so I must have an odd balance of biceps size relative to torso length and width. I gave the shirts a 5-star rating for the quality and material... I just wish the sleeves were slightly wider. Overall, Im happy with the purchase, and I will buy the tee shirts again, although I might see if the XL is a better fit for me next time.
