Perfect

The Mock is great for work under a down vest or any sweater for extra warmth/sweat protection when needed. Love it so much I got it in three colours.

Very comfortable

I love this as an undershirt that's also a mock turtleneck. Sometimes turtlenecks are just too heavyweight, so I'm excited that the lightweight NUMI turtleneck is more breathable and comfortable underneath a heavy sweater.

Two thumbs up

I've dealt with hyperhidrosis for 20 years and even with therapeutic botox, need undershirts such as these. This season has been my first time trying Numi and I am hooked. The shirts are so cozy, and I love the variety of styles such as The Mock; I'd been looking for a fitted black turtleneck and love that this one has everything I need, and doesn't attract pet hair. The only downside I experience is that it rides up a little at the hem, so I have to pull it back down fairly frequently but it's a small price to pay.

Best purchase ever

Love love this shirt. I wear it at work as a regular shirt or under a blazer. My office temperature fluctuates throughout the day and this shirt has been a lifesaver

Exactly what I was looking for

I've been looking for a long sleeve mock neck shirt for awhile, and this is the perfect one! I am curvy but usually wear a small, so I ordered the small and I think it fits true to size - it's fitted but not too tight, just right! And it's a little bit longer in the body, which I like too. I really love it (I'm wearing it right now) and I'd probably order another one!

Love It!

I love everything about the Mock Undershirt. It is not just an undershirt though. I wear it under sweaters, shirts and vests as well as by itself. The fit and quality are fabulous. It washes up great too.

About Numi

Numi was born out of personal necessity. One day our founder, Michelle, realized she never wore her favorite clothes. They were either prone to noticeable sweat stains or expensive to dry clean. When she looked for a solution, there was nothing available. And so Numi was born.

Numi is a brand that celebrates what it means to be a woman. We make consciously created products that make life a little easier for us all and inspire a culture of kindness.

Committed to Sustainability

Being mindful of our impact has always been at the core of what we do. We like to think of it as a living commitment that grows and evolves with us. This year we're taking it further. We are in the process of auditing ourselves to see how and where we can be kinder to the planet.
