Customer Reviews
Worth the investment
I was looking for something to wear under my work shirts that would actually stop sweat marks. I saw Numi's Signature Sweat-Proof Undershirt and decided to try it, especially with a new customer discount. It felt like a bit of an investment, but after wearing it a few times, I can say it's worth the money. The quality is clearly there, and it really works as advertised. I'm happy with this purchase.
Good quality, fast shipping
I ordered The Signature Sweat-Proof Undershirt and The Crop Undershirt last week. The ordering process was smooth, and I received an order confirmation right away. Shipping was surprisingly fast; it took only 3 days to reach me in California. The packaging was simple but effective. I've worn the Signature Undershirt under a silk blouse, and it really did prevent sweat marks, which was my main concern. The fabric feels soft and comfortable against the skin, not bulky at all. I followed the washing instructions, and they held up well. Customer support wasn't needed, which is always a good sign. Overall, a solid product and experience.
Undershirt works well
Got The V-Neck Undershirt. It fits. No sweat marks under my top. Delivery was quick. Happy with it.
My favorite undershirt!
I just received The Long Sleeve Undershirt and I'm obsessed! It's so soft and actually works! No more worrying about sweat. I'm definitely getting more. It shipped so fast!
Pretty good, no sweat marks
So I finally caved and bought The Essential Undershirt. My friend kept telling me how good they are. Honestly, it was a pretty easy process online, and it got here in about 4-5 days. I wore it under a black blazer, and usually I get a little nervous about sweat showing, but nothing! It felt comfortable too, not too tight. I'm glad I tried it out.
Effective but wished for more colors
I bought The Seamless Undershirt in white. The sweat-proof technology works, which is great – I didn't see any marks through my shirt, even on a warm day. The fit is good and it's quite comfortable. However, I wish they offered a wider range of 'nude' shades for different skin tones. The current 'tan' wasn't quite right for me under some lighter tops. Shipping took about a week, which was acceptable. Good product overall, just a minor point on color selection.

Does anyone know if Numi actually ships to New York City pretty fast? Need one for a big meeting next week.
Hey everyone, thinking about grabbing a Numi undershirt but I'm kinda between sizes usually. Do these run true to size or should I size up/down?
