The problem

8 hours a day at a desk. That's 2,000 hours a year.

Hour after hour at a screen, shoulders tend to drift forward, and it's easy to miss until a photo or a video call shows it.

Where posture braces go wrong

  1. 1

    Too bulky

    Vest-style braces show through a shirt, so they end up in a drawer.

  2. 2

    Wrong fit

    A strap that's too small or too stiff rubs under the arms.

  3. 3

    Needs a helper

    Some take a second pair of hands just to strap on.

This one keeps it simple: one soft strap, in your size.

How it works

One soft X-strap. On in seconds, under your shirt.

The two bands cross in an X high on your upper back. When your shoulders start to roll forward, you feel a light tug, a reminder to sit tall. No buckles, no rods, nothing around your waist.

    Settle the bands

    Use the small tab at the front of each shoulder band to pull it into place, so the X sits high on your back.

What it is

  • A wearable reminder to sit and stand tall
  • A thin, low-profile strap you can wear under a shirt
  • Sized by body weight, for men and women

What it isn't

  • A medical device or a treatment
  • A replacement for staying active
  • One size fits all

Answer to 'too bulky'

Low-profile under your work shirt.

Black bands and an open back, with no vest and no padding. Under a loose or darker shirt it's hard to spot. Under a tight or white shirt you may see an outline, so go loose or dark on day one.

Answer to 'wrong fit'

Soft stretch bands, sized to you.

The bands are soft stretch elastic, so they move with you when you reach for the mouse, the wheel or a tool. Choose your size by body weight and wear it snug, not tight.

  • Snug across the upper back, not tight
  • Nothing pinching under your arms
  • Your arms move freely

If it pinches or your arms tingle, take it off and check your size.

FAQ

Questions we get

Will it dig into my armpits?

The bands are soft stretch elastic, and the right size matters most. Choose your size by weight and wear it snug, not tight. If it pinches under the arms, it's too small: go one size up.

Can people see it under my shirt?

It's black and low-profile, with an open back. Under a loose or darker shirt it's hard to spot. Under a tight or white shirt you may see an outline.

Which size do I need?

Sizes go by body weight, from XS to 2XL: see the size chart. Between two sizes or broad shoulders? Pick the larger size. Every strap in your pack comes in the size you choose.

Can I put it on by myself?

Yes. Slip your arms through the bands like a backpack, then use the small tab at the front of each shoulder band to pull it into place.

How tight should it be?

Snug, not tight. You should feel a light tug when your shoulders roll forward, not a squeeze. If anything feels uncomfortable, take it off and check your size.

How long should I wear it?

Start with short sessions, like an hour at your desk or one drive, and see how it feels. Take it off whenever it feels uncomfortable.

Is it a medical device?

No. It's an everyday wearable strap and a reminder to sit tall, not a treatment and not a replacement for staying active. If you have a health condition, ask your doctor before using it.

Does it get hot?

It only covers your upper back, and the back is open below the X. On warm days you can wear it over a thin tee.

Can I wear it at work, gaming or driving?

Yes: at the desk, in a gaming chair, on the job or on the commute. When driving, put it on before you set off, and take it off if anything feels restrictive.

Why do I get 2 straps?

The offer is Buy 1, Get 1 Free: one to wear and one to rest, or one at home and one at work. The bigger packs bring the price down to $12.50 or $10.83 per strap.

How much is shipping?

$3.99 to the US, UK and Canada, and free on orders of $59.99 or more, so the 6-strap pack ships free.

Will I be charged for anything I didn't pick?

No. You choose one pack, nothing is pre-checked, and you see your total before you pay.
