Love this shirt!

I love this shirt! I bought two and wear them constantly. Also bought one for my mom and a friend as gifts.

Feels amazing

I wear this t-shirt daily to multiple occasions. The fabric is so breathable and buttery. It still looks new after many washes. Just love it!

Very comfortable and practical tee shirt

I was at Pacific Place the first day that Proto101 opened their store. I stopped in as I like clothes that are simple, well made, durable, easy to care for and comfy. I purchased a black long sleeve tee. It's simply a great shirt to add to anyone's wardrobe. It's a bit fitted, a bit stretchy and a better than your average black tee. It can be worn casually or when looking to dress up bit. That's kind hard to pull off. I look forward to grabbing another one when I'm downtown. I hope the company finds success as they are making good products.
