Phone down. Headphones on. Nobody else in it. One rep, then the next. That’s Respect the Set, and it goes across the back of Tee 01.

Tee 01.
Cut on a lifter.

Same chest and shoulders as the XL that already fits you. Then longer, closer at the arm and heavier, so it hangs right in the gym and on the street.

Studio render of FLEKS Tee 01 in faded black: cut like an XL across the chest, a longer body, and short sleeves that sit close on the bicep
Longer body
Stays down when you reach, press or lift.
Closer sleeves
Shorter and close on the arm. Shows the work.
Straight middle
Falls straight. No cling, no tent.
Heavier cotton
Heavy enough to hang right, on the gym floor and off it.

[Shabs is building FLEKS: gym tees for big guys who lift. He works 12-hour shifts and still trains, and even his favourite tee falls short. Here he tries on two tees he owns. Neither is a FLEKS tee.] [First tee: a charcoal tee he owns. Not FLEKS.] I've been trying a few T-shirts, and this is the one that I find I keep going back to the most, 'cause I, I like the shape on it. It fits the chest and shoulders really nice. The fabric weight is good. [What fails: too short, and the sleeves are too long.] The only thing is, I need more length on this one. Something that maybe comes down to here, maybe bring the sleeves up a little bit, like that. [Second tee: a plain black tee he owns. Not FLEKS either. What fits: the length and the snug sleeves.] Here's another T-shirt that I really like, and it just sits nicely, like, look at the length on that. Really good length. The sleeves are snug on it, though, which is, like, nice. [Card: What he's building: Tee 01, the first FLEKS tee.] What I'm trying to build with FLEKS. [Card: Cut longer. Shorter sleeves, closer at the bicep. Heavyweight cotton. Faded black and bone. In development. No sample yet. Not on sale.] If you're interested in the journey of me building the perfect T-shirt, follow along. [Card: FLEKS. Gym tees for big guys who lift. Follow the build: get first access to Tee 01.

Built between shifts.

I’m Shabs. I work 12 hour shifts, days and nights, and I still train. I wanted a tee that carried some respect, in the gym and on the street, and fit my frame. I couldn’t buy one, so I’m making it.

Questions

Who is Tee 01 for?

Big guys who lift and want a tee that carries some respect, in the gym and out of it. It’s cut on my own frame: if your XL fits your chest and shoulders but stops short, it was made with you in mind.

When does Tee 01 drop?

The first XL sample comes first, and it gets worn and washed in the Fit Test. Founders hear the date first.

What sizes will you make?

XL first, because the first sample is cut on me. More sizes follow, and the Founders’ 50 help decide which.

Is this a preorder?

No. Joining is free and commits you to nothing. You’ll never be charged without agreeing first.

Is the 3D tee real?

It’s a design render of where Tee 01 is heading. The founder video is real footage of my own tees, not FLEKS samples. Photos of the first sample go up once it exists.
