So happy I treated myself !!!

I absolutely love my numi signature in white. I’m so glad I treated myself for Boxing Day. I love having the confidence that I can wear any shirt, blouse or dress without the worry of sweating to much. Life saver. Will definitely be buying more in different colours.

Great Fit and Fabric

The fit is very comfortable and style is flattering. Perfect for layering under sweaters in the winter. I have already purchased 3 in different colors. The fabric is a good quality and has held up after several washes.

Excellent tops and undershirt

I ordered a sleeved crop top and a classic top in neutral colors and love them both! The full length top is quite firm fitting through the waist so I usually tuck it into my pants or skirt and wear it under another shirt. No more washing button up shirts after every wash!

I live in Texas and prefer the cropped top because I stay cooler, while the material on the full length top can be warm.

Peace of Mind

I rarely ever write reviews. This shirt is 100% worth the investment for many reasons. You may think this is just a piece of clothing. But really it's peace of mind. I ordered a different brand of undershirts at first and after reading reviews about the crinkly underarms, I learned about Numi. I can wear whatever sweater, blouse, or even t-shirt without worrying about soaking through them within an hour and not being able to raise my arms the rest of the day. I don't have to wash my fragile and expensive clothing after every wear and struggle to soak deodorant stains out of them. I can even re-wear my Numi shirt a few times and still smell fresh. I wish I knew about them sooner. If you're a coffee drinker or sweaty person in general who doesn't want to wear aluminum antiperspirants to try to feel confident in your life, I highly recommend you give Numi a try.

Numi is ingenious!

I sweat a LOT in my armpits and struggle with pit stains even with antiperspirant. These undershirts are ingenious. I’ve worn them under dresses, sweaters, and work tops and never gave a 2nd thought to my sweat. It also prolongs how many times I can wear a top before washing, which extends the life of the top. I own 4 of these - 3/4, signature, and crop - and may purchase more.
