Not my ideal, but a good shirt for the money
Size: Large, Color: Light Olive, Pocket Description: Front Pocket
This is a heavier-weight shirt than the standard inexpensive tee. The material is a bit stiff, even after washing. As with most of the Amazon brand shirts of various types I have bought, the sleeves are a bit shorter than I would like. Both the sleeves and overall length are shorter than the Russell Athletic shirts I usually buy, although this cost quite a bit less. The fit is also a bit more snug, so I would say it runs just a bit small.

awesome shirt
Color: Off White&black, Size: XX-Large
really was expecting to hate this shirt for some reason, but was extremely pleased with it. the fabric is not my favorite, but was still comfortable and the fabric helps retain the shape and colors. horizontal stripes can be tricky but the off white color helps as does the texture of the fabric. love it.

As far as punk rock inspired shirts go this one is
Color: Off White&black, Size: XX-Large
The shirt looks nice but the material isn't what it looks like in the picture. It's actually kind of thick, almost like a weaved cotton pattern, if that makes sense. I got it during a heatwave, couldn't wear it. But if you're looking for a decent fall weather t-shirt, well worth the grab.
