90-Day Guarantee

Join 250,000+ women who trust Ionix. Wear them for 90 days — see a difference or get every cent back, no questions asked.

The upper arm is the one place most women can't dress around. Sleeves ride up, cardigans come off when the room gets warm, and the mirror in the changing room catches it every time. This isn't a treatment and it isn't a promise about your body — it's a garment that changes what you see, the moment you put it on.

1

Even pressure, elbow to shoulderA close, consistent knit holds the soft tissue of the upper arm smooth instead of letting it move. That's the whole mechanism, and it works the second it's on — not in six weeks.

2

The same blend as our leggings90% polyamide, 10% elastane — the exact blend behind the Sculpt 3D™ Leggings that 250,000+ women already wear. It stretches over the widest part of your arm and pulls back to shape, and we already know how it wears, washes and lasts, because it's the fabric this brand was built on.

3

Thin enough to disappearFlat-finished and light enough to sit under a blouse, a work shirt or a cardigan without a visible edge. Beige for wearing under and on show, Black for everything else.

Minute 1

Roll it on. The smoothing is what it is straight away — this is the honest test.

Day 1

Wear it a full day. Comfort over eight hours is the thing most sleeves fail.

90 days

The full window our guarantee covers. If it isn't earning its drawer space, send it back.

Sold individually. One sleeve per unit — take two for a pair, four for a pair plus a spare set.

One size, built to stretch. There's no size to pick. The knit stretches to fit and pulls back to shape, so it works across a wide range of upper arms — slim through fuller — without a single measurement or a size chart to decode.

Not sure it'll fit you? That's exactly what the 90 days are for. Put it on, wear it a day, and if it's not right for your arm send it back for a full refund. We'd rather you find out than guess.

Buying a pair? Add two to your order. Your arms are a matched set.

Gather it, then roll it on. Bunch the sleeve down to the cuff, slide it over your hand and up past the elbow, then unroll it the rest of the way. Don't drag it up by the top edge — that's how knits like this get stretched out of shape.

Position it. The top should sit just below the shoulder seam of your top, the bottom just above the elbow so it doesn't fight the bend of your arm.

Wearing it. Made for all-day wear under clothes or on its own. Take them off at night — nothing with elastic in it belongs on your arm for sixteen hours straight.

Washing. Machine wash below 40°C with like colours. No bleach, no ironing, no dry cleaning — heat is what kills elastane, and elastane is what makes these work. Reshape and air dry flat; skip the tumble dryer and they'll keep their stretch far longer. Same care as your Sculpt 3D™ Leggings, because it's the same fibre blend.

Pro tip: pair them with the Sculpt 3D™ Leggings — same idea, other end of the body.

Questions & Answers

Everything you're wondering, answered

Real answers to the things women ask us most before their first pair.

Results & what to expect

Only while you're wearing them, and we'd rather say that on the way in than argue about it later. These are a garment, not a treatment. They change how your arm looks the moment they go on, and that's the whole promise. Anyone telling you a sleeve permanently changes your arm is selling you something they can't deliver. What you're buying is the option to put a top on and not think about your arms all evening.

No. A sleeve doesn't remove tissue, and we're not going to imply it does. What it does is hold the soft tissue of your upper arm smooth and still, so the loose skin doesn't move when you do — which is usually the part that bothers women most. Waving at someone, reaching for a shelf, jumping rope with a grandchild. That's the moment this is for.

This is the single most common reason women buy them. You did the hardest thing you've ever done and got handed loose upper arms as the receipt. Surgery is thousands of dollars and weeks of recovery; a sleeve is neither of those things and doesn't pretend to be. It gives you back sleeveless tops, short sleeves in summer, and the changing-room mirror — for $9.90 a sleeve, with 90 days to decide.

Then you've worn one that was under-built. Cheap sleeves go slack after an hour and the top edge has nothing left to grip with. Ours is made from the same 90/10 polyamide-elastane knit as our Sculpt 3D™ Leggings — a fabric 250,000+ women have already worn, washed and kept, so we know how it holds up rather than hoping. The other half of the fix is putting it on properly: gather and roll it up your arm, don't haul it by the top edge. There's an answer on that below. And if it still rolls on you, that's what the 90 days are for.

No — and honestly, most of the women wearing these are in their fifties and sixties. Upper-arm softening is what happens to everyone with time, weight change or both. There's no age at which a garment stops working.

Fit & sizing

There's no size to pick — it's one size, and it stretches. It's a four-way stretch knit in the same 90/10 polyamide-elastane we make our leggings from, so it pulls over the widest part of your arm and then draws back to shape rather than hanging loose. Pick your colour, pick how many you want, done. No tape measure, no size chart to decode.

Fair question, and you've earned the right to be suspicious of that phrase — "one size fits all" has let a lot of women down. Here's the honest version: it's a four-way stretch knit built to fit across a wide range of arms rather than a narrow one. But we're not going to pretend it fits every arm on earth. If you think you're at the far end of the range, order anyway and use the 90 days — that's the only way either of us actually finds out, and the refund costs you nothing.

It shouldn't. A stretch sleeve sits flat with even pressure along its whole length — this is gentle, everyday support, not a tourniquet. If you're getting a visible groove at the top edge, or a mark that's still there twenty minutes after you take it off, the fit is wrong for your arm. Don't push through it. That's a return, and the 90-day guarantee covers it, no questions asked.

They're thin and flat-finished, so under a blouse, a work shirt or a knit they sit invisibly. Under something sheer or very fitted you may catch the top edge — position it just below your shoulder seam and it disappears. Beige is the one to pick if you want them unnoticed on show; Black if you'd rather they read as part of the outfit.

Wearing & caring

All day, yes — they're built for it, under clothes or on their own. Overnight, no. Nothing with elastic in it should stay on your arm for sixteen hours straight. Take them off at night and put them back on in the morning.

Yes. The four-way stretch moves with you and the knit breathes, so they're fine for a class, a walk or gardening. Just wash them after — same as anything else you sweat in.

Gather, then roll. Bunch the sleeve down to the cuff, slide it over your hand and past the elbow, then unroll it up your arm. Don't haul it up by the top edge — that's what stretches the band and starts the roll-down problem.

Machine wash below 40°C with like colours. No bleach, no ironing, no dry cleaning — heat is what destroys elastane, and elastane is what makes these work. Reshape and air dry flat. Skip the tumble dryer and they'll hold their stretch far longer.

Ordering & guarantee

Because not everyone wants the same thing. One sleeve is one sleeve — take two for a pair. Some women want a pair and a spare set so there's always a clean one in the drawer, which is the four. Some only ever wear one. Pricing it per sleeve lets you build exactly what you'll use instead of paying for a fixed pack. Just be sure you've selected two if you want both arms covered — we'd rather say it twice than have one sleeve turn up at your door.

No, and we won't dress it up as one. The compression is gentle and supportive, not medical-grade prescription level. It's a smoothing garment for everyday wear. If you have a specific medical condition — anything involving swelling, circulation or a post-surgical arm — please check with your doctor first, and follow what they tell you over what any website says.

You're covered by our 90-day money-back guarantee — the longest in this category, and three times what most brands selling arm sleeves offer. Wear them, wash them, decide honestly. If they're not earning their place, contact us for a full refund. No questions asked. The risk sits with us, not you.
