FAQ
How do I find my size?
Grab a tape, measure your chest, and check our size chart. Between sizes? Go down if you want that fast, locked-in feel. Go up if you want a little more breathing room.
Will this shrink?
Our fabric testing showed less than 1% shrinkage, so you can expect them to keep their shape and fit wash after wash when cared for properly.
What does the fabric feel like?
Lightweight, breathable, ultra soft, and built to move with you.
How do I wash it?
Cold water, like colors, low heat dry. Or better yet, hang it up and let it air dry so it’s ready to go again tomorrow.
Can I iron it?
If you really need to, low heat only. And never on the logo unless you’re into melting things.
Who’s this gear for?
For the ones chasing PRs, the early risers, the late-night grinders, the “one more rep” crowd
Are the unisex shirts cut like men’s or women’s?
They follow men’s sizing. Ladies chasing that fitted look should size down one.
What is a raglan sleeve?
A seam that runs from underarm to collar for freedom of movement. No shoulder bunch, no distractions.
Where’s the logo?
Front left, ready to face forward with you.
Is the long sleeve shirt a tight or loose fit?
It’s athletic and sits closer to the body. Ladies chasing a fitted look can size down. Men who want a roomier feel can size up.
