Aliza Holmes
My new favorite tank from KNW

I live in a coastal town, and while I love exploring the desert, home is where the ocean is. This tank runs true to size. I am usually a small or medium, and I purchased a small and it fits perfect. I'm 5'4", 135#.

Sage Hansen
Love it!

So glad I bought this tank! The message is an important one.
I purchased a size M. I’m 5’7” and 165 pounds. I carry a lot of muscle mass so it can be a challenge to find clothes that fit well. The Medium is perfect!

So happy this came back in stock!

Such an important message and a comfy tank to boot

Sierra Mercier
My new fav shirt!

I love the fit and feel, and especially the message on this shirt. For someone with an hourglass shape, most tanks these days are too flowy and don't flatter my figure, but the cut of this tank is fitted, flattering, and and I've worn it every week so far. Love it!
