You’ve probably worked out in cotton your whole life.
I did too.
I never really thought about it—until I started noticing how heavy and uncomfortable everything felt halfway through a workout.
But if you’ve ever had one of those workouts where everything starts feeling heavier halfway through—this might be part of it.
It doesn’t show up at the start
At the beginning, cotton actually feels fine.
Soft. Comfortable. Nothing wrong with it.
Then you get into the workout.
You start sweating a bit.
Then more.
And that’s when it changes.
The problem is simple
Cotton holds onto sweat.
It doesn’t really let it go.
So instead of your shirt staying light, it slowly gets heavier.
It sticks.
It stops breathing properly.
It just feels… off.
Nothing dramatic. Just enough to throw you out of rhythm.
And that small shift adds up
You don’t suddenly stop your workout because of your shirt.
But you might:
- Slow down earlier
- Feel hotter than usual
- Adjust your shirt more than you realize
It’s subtle.
But over time, it makes your workouts feel harder than they should.
What it feels like when that’s not happening
When your clothes actually work with you, you don’t really notice them.
That’s the point.
You’re not thinking about heat, or sweat, or adjusting anything.
You’re just focused on the training.
Everything feels a bit more… controlled.
So why do people still train in cotton?
Mostly because it’s everywhere.
It’s cheap, it’s familiar, and it’s what most brands use.
Not because it’s better for training.
What to look for instead
You don’t need anything complicated.
Just something that:
- Doesn’t hold onto sweat
- Lets air move through
- Stays light while you train
That alone makes a difference.
Where Runic fits in
That’s what Runic is built around.

Final thought

it might be worth looking at what you’re wearing.
