Best undershirt I've found
The shirt feels very soft on skin and the straps are wide enough to not dig in, which is amazing. And its breathable enough that it actually makes a surprisingly good tank for the gym.
Just be aware that these run snugger then other compressive undershirts I've used. Don't make the same mistake and size down like I did. If you want a compressive fit, keep it the same as your shirt size, If you want a looser fit, definitely go up 1 or 2 sizes.

But does it come in black?
Same complements as the one in white. It's long enough that it doesn't come untucked and feels very soft and has held up well in the wash.

So comfy
Had a couple of these in white and was excited to pick up 3 in black. Super stretchy, normally get OB shirts in size 4, but got these in size 3 for a bit more compression and they’re great!
