I love this style because you can wear virtually anything underneath it and it not be noticeable. I forget that I have it on. It gives me peace of mind that I won’t have embarrassing sweat stains.
I love all my numi shirts!! They have been life changing for me. I can wear any color I want without the stress of sweat marks.
love it! Can you make it in pink please?
Very comfortable, super stretchy and soft material. It does the job of hiding armpit sweat stains and hides nicely under your clothes.
I loved this top! So comfy. Great material. Worked amazing on a hot summer day! Super cute I am obsessed
I chose the boatneck crop to be discreet under tops and dresses. I am going to trim the sleeve length a little (I did this already on another Numi undershirt) but otherwise love it.
I have a size small in the original crop but had to go down to XS in the boatneck as it was loose in the shoulders. I am 5'4", 118 lbs and 34" bust, usually wear XS if loose or S if fitted.
I’ve moved to natural deodorants without aluminium which has meant a bit more sweating than I am used to. With summer right around the corner, these tops make sure that my clothes are safe and dry and having both cropped and full length options means I can layer them under anything. I’ve tried the cropped version beneath a few of my new summer tops and it’s not noticeable at all!
