Cephalopod shirt review

I love the design, but I think it’s a bit hard to see/read with the fabric as dark as it is. I feel like it’s needs to be tweaked a little for better visuals in that sense

Really Comfy!

It's a super comfy shirt and it doesn't affect any of the sensitivities i have to certain clothing! Plus the design is rad.

Great tee!

Super soft T-shirt, unisex size. I bought a large which is my normal T-shirt size, but it is still a little long and roomy. Love that it’s dyed with algae and made in the USA with such thoughtful choices that avoid harm to the earth & water!
