Ordered a 6 pack of polos and had to exchange 2 for different sizes. Sent them back and never got so much as an email saying they received it. Had to reach out to customer service myself and got stuck with what feels like an overseas call center that can’t actually do anything. Every time I ask what’s going on it’s “we’re checking with our back office” or “we’ll follow up soon.” They never do. I’ve asked like 4 times now.
So here I am, paid for 6 shirts and only have 4 in my closet. No refund, no replacement, no real answer, just excuses on repeat. If you’re thinking about ordering, just know that if anything goes wrong you’re basically on your own. Total waste of time and money, would not order again.
I've been waiting my whole life for this company..
95% cotton and a shirt that fits PERFECTLY... Will be returning to purchase 6 more shirts next month!
I was amazed! The fit, the feel and the quality! And the look - wore this to back-to-back meetings - felt great and definitely was noticed! Great alternative to the everyday polo or button-up.
I’ve been a buyer of Polo Tees and Sene tees the past six years. I wear a lot of mock turtlenecks in the winter months. I have for over forty years so I took a chance with this new company showing mock tees. Was so happy with my first purchase I came back and bought more. Cleaned out my old tees and happy I did.
I purchased three to start with. After wearing all three I knew the quality was superior to any r-sorts I had purchased previously so I ordered six more. You can’t go wrong with these shirts
The shirt arrived well packaged as promised. It fits well and wears well all day. I will get some more to have several available when needed. Thank you for a great product.
Nice shirt.
I would prefer longer short sleeves though. Long enough to cover, go past the biceps.
If someone has nice biceps they want to show off, due to the snug fit everyone will still be able to see their biceps.
I am 6'1" 200lbs, chest size 44 waist 36 I am 70 years old and fit. I bought the 6-pack bundle mock shirt size large. The fit was perfect. The "mock" neck is only 1 inch a true mock is 2" a turtleneck is double. You have to wash this before wearing cold water hang dry. Once dried it did not need ironing the fabric held its shape perfectly. The fabric has a very nice soft feel to it. It does not feel cheap in anyway. The shirt fits like it were tailored for me. It fits great around the biceps even for my age, you young guys will look better. I'm impressed and thinking about the polos. https://www.cothirtysix.com/MIKE66117
I went out on a limb, as I am known to do, in search of some quality clothing—this time t-shirts both short and long sleeve (7 shirts in total). These are extremely comfortable and tops in quality as well as fit. I am 68, 6’ and 180 pounds and I purchased a size Large. I am so impressed with these that I am planning on purchasing a few more. One of the things I had hoped for when buying them was that they would hide a little more of my neck at the base—these really hit the mark and make this old guy look not so old. I highly recommend them and can tell you that you will love them as much as I do. Oh, and for the record, this review is unsolicited.
Fit isn’t great, I have a 42” chest, so I ordered a large. Arms are too wide, which make my arms actually look skinny, even though I work out 3 times a week and look good in my other brands of tee shirts. I threw the shirts in the washer hoping a little shrinkage would tighten the arms, but all they did was get wavy along the seems. The shirts just don’t look good on me so I’m tossing them out. Lesson learned. I hate buying certain clothes online.
