Good quality T-shirt at a very reasonable price
Size: Large, Color: Dusty Blue, Pocket Description: Plain Front
Good quality T-shirt at a very reasonable price. The material feels thick and durable, giving it a premium feel. Fits well for a size L (5’10”, 178 lbs). The only downside is the sleeve length—they run a bit long and sit just above the elbow, so they don’t really highlight the biceps.

Super comfy, great fabric and totally worth the money
Size: Medium, Color: Navy, Pocket Description: Plain Front
I love this shirt! The quality is great and the fabric feels like it will last very long. Super comfy and the color is exactly as described. Washed it a few times but didn't lose any color or shape - didn't shrink either. It's a deal for the money. Must have if you are into round neck plane t-shirts. It can be unisexual too so if you're a girl looking for a lose plane round neck t-shirt, you can buy this too

I’m a 5’6’’ 140lbs ish woman and I got a Medium
Size: Small, Color: Black, Pocket Description: Plain Front
Paid 10 bucks ! Got a medium . I am 5’6” 142lbs . It’s thick & 100% cotton. A ‘medium ’ seemed big but I intentionally ran it on high heat in the dryer & it shrunk so it fits me perfectly . The sleeves go closer to my elbows than women’s shirts… which I love. The crewneck is perfect so I can do burpees without worrying about plunging necklines. I wear a 36C bra and this tshirt is comfortable around my chest & shoulders. I carry extra weight on my belly and it’s still comfortable. Absolutely love how it looks on me. It says RELAXED fit in the title so I don’t understand why people are grumbling about the looser fit. I love it — thank you Amazon, for offering 100% cotton clothing
