My husband loved this
I got this for my husband's birthday and he’s been wearing it nonstop. He says it’s comfy and he’s pretty picky about his tees. Glad I took the chance on it.
Saw this on tiktok
Saw this on tiktok and had to buy. It’s actually really nice cotton, doesn't feel cheap or flimsy. Definitely my new favorite casual shirt.
Cool design but shipping was slow
The shirt itself is legit quality, not scratchy at all and feels thick. Took almost two weeks to arrive though, which was kinda annoying. Probably buy again because the turtle design is just too cool.
Love it!
Love it!
So soft.
Feels like a cloud and the graphic is sick. Super happy with this.
