Lifesaver Purchase

I've worn the numi crop a few times now, and it has already helped so much in keeping my garments free from stains. It's incredibly comfortable, thin enough to wear under t-shirts but not see-through so you can wear it by itself as a shirt.

Exactly What I Needed

The Numi crop is comfortable and works perfectly. The shorter length is easy to wear under sweaters and doesn’t add any bulk. This has been a wonderful solution for me.

Comfortable fabric and the underarm was not bulky which had concerned me prior to trying. I was hoping it would would be worth the investment as the items are not that cheap but hopefully it will last and be worth the investment

Perfect layering piece

Love that it's reversible (crew-neck or a low-ish V-neck) and can be layered to look like a T-shirt under a button-down or invisible under a sweater; also works well under a sheer top without distracting. I was worried it would be too small, but I ordered their suggested size, and it is a great fit for my purposes. If you want to wear it as a stand-alone tee, you may want to size up to get a more blousy effect. Love!

Love!

Incredibly comfortable. I'm not afraid to wear clothes that are tight in the pits now!

A Total Win

I am very pleased with The Signature! I was afraid I'd feel really hot wearing it, but I have not felt overheated. The material is breathable and allows fabric to move freely over it. My clothes do not cling or get bunched around it. Most importantly, it has kept my clothing clean and free of sweat stains. I plan on buying another one!

Love these tops!

Comfy and sweat-wicking—the perfect combo! I have three of these tops and will keep buying more.

I can now wear shirts that aren't black!

Even with using prescription-strength anti-perspirant, I will have pit stains within an hour of putting on a shirt. Because of this, I have almost exclusively worn black shirts for years. But no longer! I bought two of these shirts to try out and can now go all day long with no pit stains! I even tried going on a long walk with a sweater on and did not sweat through it. These shirts are very comfy and are thin enough to be able to wear under another top without having visible lines. This shirt is worth every penny.

Comfortable and easy to launder

I like the fact that these shirts are very slim to wear as well as easy to launder (unlike some which need to be turned inside out otherwise the perspiration odor will remain with the shirt.) They feel sleek against the body. I also like the almond color.

Loved this

Worth the high price. Definitely will be buying another. Fits nicely under most tops.

A new wardrobe staple

The first day I wore a Numi undershirt, I fell in love. It was so comfortable and sleek, and it delivered on its promises. No more wet underarms. Now my tops need less laundering, and I wear my clothes with new confidence. The Three Quarter is even more invisible than the Signature under long sleeved shirts. Love it!

I love my new Signature tops. They are great quality. I bought two to wear under my shirts but I've discovered that it makes sense to wear them under my sweaters too so I can reduce my dry cleaning costs. Super happy with the product and will buy more in future so I can wear one every day. I bought the size Small and it fits true to size. I got the white and almond - both are lovely colours.

Freedom!

I love these undershirts. Been wanting to try them for a long time but was unsure about the price. I finally took the plunge and couldn’t be happier! Immediately realised I needed to order more! I usually have to wash my sweaters and tops after one wear but now can get multiple wears out of everything and don’t need to limit myself to only colours and fabrics that don’t show sweat. Super discreet under the finest tops. Wasn’t too sure whether to get XS or S, I’m usually a European size 36 / UK size 8. The size S was perfect if maybe slightly loose in the sleeve. The almond colour was slightly darker than I expected but still worked well as a “nude” under tops for my pale irish skin tone

Versatile and chic

Love it. I was worried the relaxed fit wouldn’t look flattering on my 5 foot 6 frame but I ordered a medium (my normal size) and it fits great, relaxed but not sloppy. The cut is flattering, the fabric drapes beautifully and wearing it with the shirt tucked in gives it an instantly polished look. Wore this while making dinner with the kids and it survived all sorts of spills with no problem. Will be wearing this on repeat for sure.

Perfect undershirt

I love this undershirt. The material is so soft and breathable while also keeping my warm as a base layer. Also great for preventing sweat stains! I will be purchasing more.

Great fit; great look

The signature shirt is really comfortable and great for under blazers or other work tops. It looks good on its own, too. The black is opaque enough to wear on its own. Would definitely recommend.

Exceeded my expectations and I love it!

The fit and quality of the shirt was amazing and looks classy. I’m usually a mess and am an active working mom so typical silk shirts do not last long with me. Loved that this shirt is washable, looks great on and after washing and I won’t be sending more clothes to the landfill. I also purchased and wore it with the crop and I was pleased that it was unoticeable under the white silk. I would recommend this product and hope to purchase at least another shirt color.

Exactly what I was looking for

I love The Three Quarter. I've been wearing another brand, but the length was too short, so I was constantly having to retuck. These fit perfectly, are super comfortable, and so far, seem to be wearing well.

Comfortable

I ordered the navy and then the black because I loved them so much. Please make a slimmer pant, this one is great but would be nice to have a slimmer version!

such a great solution

this is a comfortable, environmentally friendly garment that absolutely absorbs sweat without me even feeling or smelling it. wearing NUMI underneath my outfits protects my beautiful clothes and i am so grateful. i am 5’3 and about 130 lbs and the M is a comfortable, true to size fit. i could size down if i wanted something snugger, just a matter of preference. #shoplocal
