Super breathable and comfortable
It was my first time in Proto101. The mall was actually closed and I just happened to notice that her store was still open so i decided to walk in and browse. Liyin was still there helping another customer and she was so friendly and welcoming. I could tell she was very passionate about the product. She approached me and gave me lots of information and suggestions especially around fitment. In the end I walked out with a purchase and am so glad I did. Will be back the next time I’m in Seattle!

One of the best feeling T-shirts I’ve ever owned
Incredibly soft, silky smooth fabric with lots of stretch but also recovery ( I.E.fabric returns to original form), but doesn’t look the least bit synthetic. Fit is good, though for my long torso, I would prefer another inch of length. This is probably not an issue for most people. All things considered highly recommend this products, comparable quality to $80 plus T-shirts.

Great Fit
The shirt I’d so comfortable. It also wicks better than any other fitness shirt I’ve worn. It’s pricey but I think it will outlast any other brand name shirt.
