Textile care and firm stitching
How it informs your senses
Thoracic wrap
The band wraps around the lower perimeter of the rib cage, providing a tactile boundary.
Active expansion
As you breathe in, the intercostal muscles push the elastic fabric outward.
Proprioceptive response
The elastic pressure sends direct feedback to the brain about the range of movement.
Support during exhalation
The band follows the natural recoil of the ribs as you completely release your breath.
Perception of your breathing over time
Clear tactile feedback
You notice exactly where your ribs move and where they stay rigid.
Greater lateral ease
You manage to expand the circumference of the strap with fluid, tension-free inhalations.
Internalized pattern
You maintain active rib breathing even when you are not wearing the band.
Protected and recyclable shipping
We package the band rolled in kraft paper inside a cardboard box with no unnecessary plastics. It will arrive with its corresponding instructions and washing tips label.
Adjustment and mobility routine
Put the band on during your morning stretches and complete ten rib cage expansions.
Loosen the strap and store it rolled up in a dry, ventilated place.
Close your eyes and imagine pushing the band to the right and left at the same time.

"I use it in my Pilates classes and it has completely changed how I feel my diaphragm. The cotton feel is very pleasant."

"It does not bother me under the arms at all, and the buckle does not dig in when lying on my side. Very good purchase."
