Amazing!

I am so impressed with everything about Nerd Jar. The quality and design of their clothes is so simple yet fashionable and the quality is amazing.

It is so important for us to be more sustainable and help our planet and I love that that is their main mission.

I love my new quirky tee! Not only the design, but I feel good wearing it knowing I’m supporting an eco-first mindset.

I even planted a tree with my order, yay!

I struggle to find t-shirts I like, but I’m a big fan of these!

The subtle, funky designs mean I can wear it pretty much anywhere (work, nights out, etc) and still have a bit of fun. Super comfy as well!

Great quality product for a good cause and a correct price.

The helpdesk was very helpful even after I had entered my address wrong. They were very patient and did not stop until I received my order. One of the best shops I ordered from in this pandemic.

Thanks again for the great service!

I purchased the Earth Sweater in pink! Love it, good quality and really soft!
