Apparel only. Just our name, spelled in the lab’s alphabet.
The Subject
Bred in the lab. Built for the street.
Lab Rat Wear makes original graphic tees and tanks for people who treat the gym like a lab. Every design is our own art, printed on demand in gold on black, and fronted by one very committed test subject: the Rat. He’s out now. Wear the science.
Our designs borrow from the lab, from the “For Research Use Only” vial label to fine gold line drawings of real molecular structures. Lab-inspired, gym-ready, and made to start conversations.
Apparel only. We sell clothing, not products for consumption. “Research Use Only” is a design theme, not a product claim, and nothing on this site is medical advice or a health claim.
Questions
FAQ
Do you sell anything besides apparel?
No. Lab Rat Wear sells apparel only. Our designs are inspired by chemistry and lab culture, and nothing on this site is a product, recommendation, or claim about any substance.
How does shipping work?
Each shirt is printed after you order, then shipped to you. Production and delivery times can vary by location and season. Shipping is not included in our prices: it is paid by the customer and calculated at checkout, where you will see the shipping options, cost and estimated timing.
What is your return policy?
Because every shirt is made to order, returns and exchanges are handled case by case. If something is wrong with your order, reach out and we will work with you to make it right. Full policy details will be posted before launch.
How do the shirts fit?
The men’s performance tee has a standard athletic fit, and the women’s performance V-neck has a more tailored cut. Every design is also available as a men’s muscle tank (soft ring-spun cotton with dropped armholes) or a women’s performance tank (moisture-wicking polyester with a scoop neck), and as a soft ring-spun cotton tee in a unisex or women’s cut. The premium performance tee (Paragon 200) is a lightweight microfiber polyester tee with UPF 50+ rated UV-protective fabric. The men’s performance tee comes in S–3XL, the women’s V-neck in S–2XL, both tanks in XS–4XL, the unisex cotton tee in XS–5XL the women’s cotton tee in S–2XL and the premium performance tee in S–3XL. Sizes 2XL and up cost a little more. A full size chart will be available on each product. If you are between sizes, we generally suggest sizing up for a relaxed fit.
What does “printed on demand” mean?
We do not keep warehouses of stock. Your shirt is printed when you order it, which means less waste and more room for new research collection designs. It may take a little longer than off-the-shelf retail, but each one is made for you.
