UNDR Men's Core Support Band
The details
Targeted. Precise. Invisible.
The UNDR Men's Core Support Band focuses compression exactly where men carry the most tension: the lumbar region and abdominal core. Worn discreetly under any shirt, it gently engages the core throughout the day, actively supporting posture without restricting your range of motion.
The seamless, pull-on nylon design means it is in place within seconds. Designed for the desk, the boardroom, or the long commute. Wherever your day takes you, the Core Band follows.
Available in One Size (High-Stretch).

Invisible under everything
Seamless edges. Thin profile. Under a dress shirt, a tee or a suit, nobody sees a thing.
-
All-day support
From 6am to 10pm. The layer holds where you decide it should.
-
Breathable second skin
Lightweight knit that moves heat out. Built to be forgotten while you wear it.
-
Discreet delivery
Plain packaging, no logo on the box. What is inside is your business.
Quiet engineering.

Graduated knit zones
Firmer where you want hold, lighter where you move. You feel the layer settle, then you stop thinking about it.
-
A quiet reminder
The weave keeps gentle tension across the back. At 6pm you notice you are still standing tall. That is the felt difference.
-
Edges that stay put
Flat bonded hems under a tucked shirt. No ridges, no adjusting, nothing that shows.

“Velikost M sem moral zamenjati za L, ker mi je bila okoli prsi preveč tesna. Vračilo je bilo sicer preprosto. Velikost L mi odlično pristoji in pod delovnimi srajcami opravlja točno tisto, kar potrebujem. 👍”
