Onyx Shorts
Premium athleisure · 210 GSM
Tired of tanks that fall apart by week 3?
Most stretch out and end up binned within a month. This 3-pack keeps its shape wash after wash — the tank you train in, then actually want to throw back on when you head out.
The fabric
210 GSM. Heavier on purpose.
Most tanks are 150 GSM — thin, and they stretch out fast. Ours is 210 GSM: 95% cotton for the soft, breathable feel, 5% spandex for the structure. You'll feel the difference the second you put it on.
Why it lasts
It moves with you, then snaps back.
The cotton-spandex blend hugs your shoulders and chest, then returns to shape after every wash. The fit you bought on day one is the fit you keep on day one hundred — no sagging collar, no baggy waist, no binning it in a month.
- Holds its shape, wash after wash — dense 210 GSM, never thin or saggy
- Athletic cut that hugs your shoulders and chest — never baggy
- Gym to everyday — soft, breathable, the one you reach for

Everything you need to know
before you order.
Honest answers. Nothing left out.
The difference is in the fabric. Most tanks on Amazon run 140–160 GSM — thin, and they stretch out fast. Ours is 210 GSM, 95% cotton, 5% spandex. Denser. Structured. Holds its shape because the fabric is built to.
That's not a claim — that's what 210 GSM does that 150 GSM can't.
Yes. The 210 GSM cotton-spandex blend snaps back after every wash. No sagging collar, no stretched shoulders, no losing the structure. The same fit at wash 1 and wash 30.
That's what 5% spandex does when the base fabric is heavy enough to support it.
Most of what's sold as quality is good photography. The real test is 20 washes in. That's exactly why we offer 30-day returns — we want you to put them through your actual routine before deciding.
If they sag, stretch, or disappoint: send them back. We're confident they won't.
The cut follows the shoulders and chest. It works on lean builds, athletic builds, and broader frames — not just bodybuilder physiques.
If you prefer a looser look, size up one. Not sure? Try your usual size first. Our returns cover swaps, so there's no risk in ordering.
Split the total by three. That's what each tank actually costs you — less than a single H&M tank that'll lose its shape within a month.
One 3-pack a year instead of buying cheap replacements every few months. The maths is straightforward.
These tanks fit true to size. Check the size guide for exact measurements. If you're between sizes or prefer a more relaxed fit, size up one.
The cut is designed to sit close to the body — fitted, not tight.
30 days from delivery, full refund. Items must be unworn with the original tag attached.
Wrong size? We'll exchange it. Not what you expected? Refunded. No complicated process, no hassle. We offer this because we're confident in what we sell.
Been through so many tanks that fell apart within a month. Training four times a week, wash every few days. Still sitting exactly the same as when they arrived. The collar hasn't moved. That's all I needed.
Verified PurchaseAlways had the same issue — tanks are either too baggy or cut wrong. These follow the shoulders and chest without squeezing. Put one on before training and actually felt good going in. That doesn't happen often.
Verified PurchaseUsed to buy a couple of cheap ones every few months when the old ones gave up. Black, white, grey — covers everything. One order and I haven't thought about gym tops since. Exactly what I wanted.
Verified PurchaseTrained in it, kept it on all day. Coffee, errands, the lot. Doesn't read as gym kit — just looks like a decent fitted top. Two people asked where it was from. Comfort held all day too.
Verified PurchaseWasted money on gym tanks so many times. Always thin as paper and stretched out immediately. Took a chance on these. Fabric is noticeably thicker. Several washes in — holding exactly as promised. Should've switched sooner.
Verified PurchaseThe fit shows the work. Hugs the right spots without being too tight. Wore it to the gym and then out for drinks — worked for both. Can't really ask for more than that.
Verified PurchaseComfortable enough to forget you're wearing it. The 95% cotton makes a real difference — breathes properly even through a heavy session. Wore it for a full day and had no reason to take it off.
Verified PurchaseBought the 3-pack. Then ordered another 3. The quality is what you hope for but rarely get. These are genuinely what they say they are. No surprises, just exactly what was promised.
