As a huge Batman fan and a gym regular, this shirt is just perfect. The material is super soft and has held up really well after multiple washes. I've gotten so many laughs and nods at the gym – it’s a total conversation starter. Finally, a pump cover that shows off my sense of humor along with my (aspiring) gains.

I've worn and washed this shirt a dozen times already, and it still looks brand new. The fit is perfect, and it's soft enough to wear all day. The Cookie Monster design is printed perfectly. It’s my new favorite shirt for both the gym and casual wear.

Absolutely love this shirt! As a bigger guy who's also a huge Batman fan, this design is hilarious and perfect. The material is super soft and the print quality is great. Got my normal size and it fits perfectly.

Wore this to The Weekend concert and got so many compliments. This shirt perfectly combines my love for The Weeknd and the gym. It's comfortable enough to sweat in but cool enough that I’ve worn it out

Saw a guy wearing this at my powerlifting gym and had to ask where he got it. So glad I found it here! The fit is great and the design is awesome. It’s become a staple for the gym. Perfect for anyone who takes their training seriously.

Bought this for my boyfriend and he hasn't taken it off! He's all about that bulking life and loves the Hulk, so this was a perfect match. The sizing was accurate and he said it's one of the most comfortable shirts he owns. Big win!

My husband is a huge Batman fan with a great sense of humor. When I saw this shirt with fat Batman on a scooter, I knew it was perfect. He hasn't stopped wearing it since it arrived! The fit is true to size and the material is soft. A hilarious and well-made tee.

As a powerlifter and a huge AC/DC fan, this shirt feels like it was made specifically for me. The quality is top-notch, and the design is a great conversation starter. It’s refreshing to see gym apparel that’s actually clever and not just another generic brand logo.

The design is genius and the quality is top-notch. It’s become my go-to for the gym. Fits true to size and the graphic is super soft, not that stiff plastic-y feel. Next Cult Brand nailed it with this one.
