The Classic F Tee
Some people wear logos.
Some people carry a signal.
This one keeps it quiet.
Just a small F on the chest.
No noise. No explanation.
If you know, you know.
Built on the AS Colour Classic Tee —
a piece that doesn’t try to impress,
but ends up lasting longer than most things that do.
220 GSM heavyweight combed cotton
Structured, but still breathable
Holds its shape, doesn’t give up after a few washes
Preshrunk, because surprises belong elsewhere
Reinforced where it actually matters
Fit
Regular cut.
Not slim. Not oversized.
Just… right.
The kind of fit you don’t think about,
until you realise you’ve been wearing it all day.
Details
Ribbed neckline
Side-seamed construction
Shoulder-to-shoulder taping
Double-stitched hems
Nothing fancy.
Everything intentional.

Grab your favourite tee.

Frengineer Note
This isn’t a “statement piece”.
It’s what you wear when you stop trying to make one.
Build in it.
Fix things in it.
Drive somewhere with no plan in it.
Or just stand there…
after stepping in dog shit…
and accept your fate.

Care
Take it easy on your gear.
Built for real life, not careless ones.
Give it a proper wash, hang it where it can breathe, and it’ll stick around longer than most things in life.
Each piece comes with care tips—nothing fancy, just the basics to keep it going.
Design
It’s not just about the materials.
It’s how it’s made.
Every piece carries a bit of hands-on thinking, built with care, not just put together.
