Customer Reviews
Overall rating: 4.8 / 5 from 3046 reviews.
Really love this blue color. It goes almost gray. The fabric feels like a thick cotton. The mock neck is not too high and the length is not so long that you can still wear tucked or untucked. Not in love with the CO36 branding at the bottom but it’s fine.
Literally the best shirts I've ever owned...
Love the fit and material
Great mock neck T-shirt. I love the fit, the quality, and the overall look. I’ve been looking for a T-shirt like this for a while, and this is exactly what I wanted. I immediately ordered a few more colors. Highly recommend!
I'm very impressed. Material, stitching and fit are all fantastic. The mock turtle neck has just the right amount of rise, a problem with other manufacturers. Color choices are excellent.
The mock feels like magic.
The Mock T-Shirt is wonderful. I can wear it for any occasion...Yes even to a outdoor wedding.
It has a nice heavyweight feel, and it fits and feels great. My wife says it looks wonderful.
Great fit. Very impressive quality merchandise.
Great fit
Ordered one bundle, gave one mock-neck to my partner. Ordered a second bundle, gave him two. Ordered a third bundle and kept them all for myself. High neck works great under a crewneck sweater. Love the ribbed sleeves. What could be better?
The mock neck T’s have the perfect blend of quality and a crisp look for dressing up with a blazer, as well as the casual flexibility to wear with shorts and dock shoes! They are my new “go to”!
Excellent fit, style & quality!
The fit is exactly what I was looking for - and what Co36 advertised.
My husband loves them
Casual dress in these T-shirts. Really looks and feels high quality.
Attractive and well-fitting shirts.
Looks black not blue. Fits great!
Great fit! Beautiful fabric
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.
The shirts have a very unique feel. The fabric has real substance; it feels heavy but is lightweight. The collar is nice, and the overall fit is good.
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.
These tees make my husband look thinner in the waist and fuller in the chest. Best fit ever!
Fits well, fabic is soft and hugs through the shoulders and arms creating a flattering fit for any body style
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
Love it
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.
It is sporty and dressy depending how you wear. Very well made.
This shirt is well made and washes beautifully.
Nice fit ge really likes it
Soft, long and great fit
Great t-shirt 👍🏻
Super soft shirts that fit great!
I like these shirts. Love the feel. Fit is a little loose in sleeve even with the cuff. If you have bigger biceps it will look better.
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
The shirts feel and look great.
