Customer Reviews
4.8 4 verified reviewsHubby loves it!
Got this for my husband and he literally ripped open the package and put it on. The neon really pops and the fabric feels super soft, not scratchy at all.
Pretty cool tee, glad I sized up
I was kinda iffy about how 'neon' it would actually be, but the calculator graphic looks pretty vibrant in person. The organic cotton feels good, and honestly, the advice to order a size up for US customers was spot on, it fits perfectly.
My new favorite everyday tee.
Seriously, this shirt is awesome. I wore it out last weekend and got so many compliments on the retro calculator design – it's just so unique and vibrant. The organic cotton is surprisingly soft and breathable, making it super comfy for all-day wear, plus it's cool knowing it's PETA-Approved Vegan and carbon-neutral. It's quickly become my go-to for chill vibes with a bit of a throwback edge.
