Customer Reviews
4.8 4 verified reviewsPretty good quality, mind the sizing.
Honestly, I was a bit skeptical about another 'organic' tee, but this one actually feels substantial and super soft against the skin, not flimsy at all. The design is crisp and hasn't faded after a couple washes. Just make sure to size up if you're in the US; I usually wear a medium but went with a large, and it's a perfect relaxed fit.
Husband loves it!
My husband's a huge logic gate nerd, so this was literally perfect. He wears it all the time now and says it's super comfy.
Totally worth it.
Obsessed with this tee.
