Men's relaxed fit cardigan
Size: XX-Large, Color: Dark Blue Stripe Knit, Size: XX-Large, Color: Dark Blue Stripe Knit
This Amazon Essentialsl men's relaxed fit cardigan is a stylish option for men. The cardigan is short sleeved and relaxed in fit. I ordered an XXL for my huband, which is his normal size, and it fits him well and is relaxed through the shoulders and body of the cardigan. The one we chose is blue and white striped with a white border on the sleeves and hem and a white collar. It's 100% cotton and is soft to the touch. It looks really nice on my husband, and he says it feels comfortable to wear. The weight is somewhat heavy, so I think for him, he will mostly wear it when it's a bit cooler. It gets very hot here in summer, but this will be nice when the weather cools off. He often wears short sleeves in colder months, too. This cardigan can be machine washed in cold, but it should be dried flat (the way you generally dry sweaters so they'll keep their shape). It's a very nice looking cardigan, and it looks great on my husband. I'm very pleased with the style and the quality.

Unbeatable Price! Great Quality!
Size: Medium, Color: Dark Green Stripe Knit, Size: Medium, Color: Dark Green Stripe Knit
I was very impressed with the softness and quality of this shirt. I am 6'1 and 195 lbs. and the medium shirt was a perfect fit. I will agree that the size is true to fit. The only thing I didn't like was the length. The length is short, so it comes to just to the top of my waist when wearing, however, that is the style of this cardigan. A longer length is my personal preference since I am taller. Also, with this being cotton, I would not recommend putting this garment in the dryer as it will likely shrink. The color (I got green) is just as pictured and the green and navy color mix blend well together. Although knitted, you do not see through the shirt, so an undershirt is not required. The price tag is unbeatable as you will not find a knitted cardigan anywhere else at this low price. Overall, I think it is a great buy, and I would highly recommend it.

Great fit.
Fit Type: Regular Fit, Color: Charcoal Heather/Charcoal Heather, Size: 5X-Large Big
Im 6'4 360lbs. They're not thick but and the neck is a little looser than what im use to. But overall im happy with the quality and the length of the shirt. I got a big belly and the shirt doesn't expose any of my belly and not too long where. It looks like a tall tee. Definitely will grab these again.
