What if it doesn't fit?

We publish detailed size charts to make sure you find the right fit the first time. You just need to check it against your own measurements. However, the lab coats can be returned or exchanged if you cover the shipping and restocking cost (usually around $12 total in the USA).

Will my lab accept these?

Check with your lab safety officer about hazards, laundering details, and any compliance markings you may need (FR, CE, etc.) For more details, visit our Lab Coat Safety & Care FAQ Page.

Group orders, embroidery, and POs

We can take group orders to save on shipping costs and we can accept Purchase Orders for a minimum of 8 lab coats. We will also offer embroidery options before shipping. See our group orders page for more details.

The "Louis" Men's Black Cotton Scientist Lab Coat

Name: The Louis - Men's Cotton Lab Coat (Black)
Brand: Genius Lab Gear
SKU: LCPMBL01-S
Price: 59.95 USD
Availability: InStock

This lab coat is made from 100% cotton and all-metal snaps, which is accepted in most standard laboratory environments including introductory chemistry and biology lab classes. Please check with your lab safety officer for compatibility.

Fire:

100% Cotton provides better protection against flames than polyester or poly-cotton mixtures because polyester will melt to your skin and prevent emergency lab coat removal. 100% cotton is not “FR”, “flame-retardant” or “fire-proof”, and will burn slowly if exposed to intense flames. If your lab requires “FR” lab coats, get on our email list for our future release with flame retardant materials.

Acids:

Most lab coat materials, including 100% cotton, absorb strong acids and may develop holes from exposure. Always wear a neoprene, rubber, or PVC apron and long acid-resistant gloves on top of your lab coat when handling strong acids.

Finally found my coat!

It's abundantly clear that this lab coat was designed by people who wear them. I never find myself fumbling to stow something, all of the pockets and holders are right where your brain expects one to be. They look great, too!

I have an exception in my contract specifically to allow me to wear a lab coat in place of a blazer as part of the faculty uniform. THIS is the lab coat I choose to wear all day. I've been through dozens of styles, trust me, just grab a Louie and don't look back.

XL / None

Great fit

This lab coat stands out for one simple reason: it actually fits tall people the way a lab coat should. It looks professional, feels durable, and functions well in day-to-day use. If you're a tall guy tired of short sleeves and boxy cuts, this is one of the few lab coats that gets it right.

"The Louis" Lab Coat

Named after Dr. Louis Pasteur, the French chemist and microbiologist whose pioneering work had a profound impact on medicine, agriculture, and industry.

Dr. Pasteur overturned long-held assumptions about the origins of germs. His bold beliefs in the power of science also lead him to introducing the first successful rabies vaccine, saving countless lives.

Every stitch of The Louis lab coat is designed for scientists: from chemistry to microbiology to genomics, we're thinking of how your daily needs are different from doctors.

Features that Make research effortless

First reactions from the Louis lab coat

Marc, Chemistry Educator

"I love my Louis lab coat. As a high school chemistry teacher I have more than enough pockets to keep track of the pens, stamps, etc is phenomenal. I love the cuffed sleeves and the belt that helps keep me from getting caught on lab tables as I move around the tables. I know the final version will only get better."

Andres, RA in Inorg/Org Chemistry

"Feels amazing, looks professional. Very functional (and was noticed by others as such), has a pocket and loop for everything. Can take a lot more than a thin blended fabric mix, and the extra thickness gives more absorbance and time to remove in case of an incident. Absolutely satisfied with the purchase."

Raul, Scientist and Scicomm personality

Love your design! It's so comfy and the touch of the cotton is amazing!!! It's a perfect fit.
