Dieses Sakko hat bewusst keine Knöpfe und wird immer entspannt offen getragen. Dadurch sitzt es locker, modern und spannt nie. Das cleane, minimalistische Design macht es extrem vielseitig – elegant genug wenns schick werden muss, aber gleichzeitig lässig und sportlich. Nie overdressed, nie underdressed. Perfekt für Männer, die keine Lust auf ein klassisches Sakko haben.
Wir verwenden einen hochentwickelten Jersey aus Italien: ein technischer Polyamid-Elasthan-Stoff aus dem Hochleistungssport. Das Ergebnis: maximale Elastizität, geringes Gewicht, keine Falten – kombiniert mit einer edlen, modernen Optik.
Maximaler Komfort durch innovativen Performance-Jersey aus Italien: die hochwertige Gewebe ist extrem leicht, elastisch und atmungsaktiv. Das Ergebnis: ein Anzug, der sich wie Sportswear trägt, aber wie ein klassischer Anzug aussieht.
Kein Einlaufen, kein Verziehen: auch nach häufigem Tragen und Waschen bleibt der Anzug in perfekter Form. Die technische Jersey-Konstruktion sorgt für dauerhafte Elastizität und strukturelle Stabilität bei gleichzeitig hohem Komfort.
Volle Flexibilität in jeder Situation: ob Sitzen, Laufen oder Reisen – der Anzug macht jede Bewegung mit. Der elastische Jersey sorgt für absolute Bein- und Armfreiheit, ohne die Form oder Eleganz zu verlieren.
Der cleane Stehkragen verleiht dem IOS JACKET einen modernen, minimalistischen Look mit sportlich-eleganter Wirkung. Reduziert auf das Wesentliche wirkt das Sakko entspannter und zeitgemäßer als klassische Modelle.

Thanks to its innovative fabric construction, our performance flex jersey offers a great deal of flexibility and freedom of movement. This allows us to create the perfect fit that is close-fitting but not restrictive.
Our multidirectional stretch ensures high dimensional stability and resilience, which prevents wear and creasing in the long term.
The combination of ultra-fine microfibers with Lycra makes the fabric particularly lightweight. In combination with a special knitting technique, the fabric always remains particularly smooth, making it ideal for traveling and on the go.
This is how your jacket is constructed.
Reinforces fine fabrics and shapes a natural breast form. Over time, this insert adapts to your body and gives you a unique fit.
A precisely coordinated arrangement of natural fabric layers that forms a stable chest and shoulder structure.
This inner finish preserves the natural shape of the breast with a perfect drape.
The high-quality inserts are light as a feather, comfortable and give the jacket volume.
Alle IOS Produkte bieten dir maximalen Komfort, moderne Schnitte und besonders hochwertige Qualität.

The jacket has a modern, more body-hugging fit, but as it cannot be closed, it offers a little more room than a normal slim-fit jacket.
Use your usual jacket size as a guide and check the notes on the product page. The modern slim fit fits cleanly at the shoulders and remains comfortable in the torso. If you are wavering between two sizes, opt for the larger size. Feel free to use our size finder on every product page.
Yes, our jacket is made for everyday comfort.
The styles combine a modern fit with freedom of movement so that you feel comfortable in the office, at appointments or on the go. The fabric is comfortable to wear and is designed for easy care. This makes the suit suitable for long days without much effort. It doesn't crease and always keeps its perfect shape without wearing out. A comfortable slim fit jacket that always makes you look and feel good.
The IOS JACKET clean is not only perfect for days at the office, but also for smart occasions. This jacket is also perfect as a guest at a wedding, as it is smart but not overdressed. You'll feel comfortable and look good!
Depending on the occasion, it can of course also be perfectly combined with our IOS PANTS and can therefore be easily adapted to the required purpose.
Decide according to the occasion, your style and the pieces you already wear.
Navy and black are very versatile and go with most business outfits. Beige brings summery warmth to your look. Dark Grey and Steel Blue are modern alternatives to the classic blue and dark grey, they add a modern accent but remain understated.
Take a look at the pictures on the product page and choose the suit that is easy to combine with your shoes and your existing wardrobe or simply the one you like.
The IOS JACKET clean offers so many possibilities. It goes just as well with jeans or chinos as it does with classic cloth trousers. The colors can also be combined well and in a variety of ways, and you can find a number of possible looks on our product page.
In addition to the classic shirt, a simple T-shirt or fine knit can of course also be worn under the jacket, depending on the occasion, or something with a stand-up collar to match the collar of the JACKET clean.
You choose the model, color and size, add it to the shopping cart and go to the checkout. Returns and exchanges are quick and easy via our returns portal.
In the checkout, you will see the available shipping options and payment methods. After placing your order, you will receive a confirmation and can contact support if you have any questions.
If something doesn't fit, you can exchange it for the right size free of charge or simply return it.
Hanging and airing is usually sufficient.
After wearing the jacket, hang it on a stable hanger, gently smooth out any creases and air it briefly. Store it in the wardrobe with some space to keep its shape. Check the care instructions before cleaning. When traveling, a light cover helps to ensure that the jacket arrives protected.
Please always dry clean the jacket according to the care instructions.
The combination of ultra-fine microfibers with Lycra makes the fabric particularly light. In combination with a special knitting technique, the fabric always remains particularly smooth and is therefore ideal for traveling and on the go, so it always looks like freshly dressed even after a long journey.
