Pull your shoulders back — and keep them there.

★★★★★

Loved by those who already own one

An adjustable X-cross frame that gently pulls your shoulders back and holds the line — thin enough to wear under a t-shirt, all day, every day.

What makes it different

Four things that make it work.

Hollow-weave adjustment webbing

The woven X-bands flex with your shoulder blades instead of fighting them, so correction feels like support, not restraint.

Independent strap tensioning

Each side adjusts on its own velcro run, so uneven shoulders still get an even line.

Breathable lumbar panel

A ventilated lower band anchors the frame at your waist without trapping heat.

Low-profile shell

Under 2.1 oz and a quarter-inch thin — it reads as a seam, not a brace, under clothing.

Made to disappear under everything you wear

The same frame holds up whether you're at a desk or out the door.

Built for a full day, not just a workout

Slip it on under a t-shirt, blouse, or button-down and forget it's there — most people wear it through a full day without a second thought about how it looks underneath.

Sound familiar?

Desk hunch catching up with you?

✕Rounded shoulders that don't reset, even when you "sit up straight"

✕Tension across the upper back by mid-afternoon

✕A slouch that shows up in photos before you even feel it

✕One more thing on the list you keep meaning to fix

TrueLine Pro gives your shoulders somewhere to rest — strap in, and let the frame do the holding.

How it's worn

On in under a minute, every morning.

There's no wrong way to feel a little unsure on day one — here's the fit that works for most people from the first try.

Step 1–2

Slip both arms through like a vest, then pull the straps until your shoulders sit back naturally.

Step 3–4

Secure the lower strap so the frame can't slip, then go about your day — most people forget it's on by lunch.

Frequently asked questions

Will it actually fit me?+

Yes — TrueLine Pro comes in sizes from S up to XXXL, and each side straps down independently, so you get an accurate fit rather than a generic squeeze.

Can I wear it under my clothes?+

Yes — it's built to sit under a t-shirt, blouse, or button-down without printing through. Most customers wear it to work.

How long should I wear it per day?+

Most people start with 30–60 minutes a day and build up from there as it feels comfortable. Listen to your body and take breaks as needed.

Is it machine washable?+

Hand wash in cold water and air dry. Avoid the dryer — it protects the elastic tension in the straps.

How long does shipping take?+

5–7 business days across the US, with free shipping on every order.
