Product Description

Reduce sweat, don`t prevent it. For automobile owners, the "MK" marking system may just mean a simple model number. For the team of developers, though, these two letters alone represent months or even years of painstaking work and innumerable tests. The strategic focus is not just the design, but rather is more performance enhancements of the product: More horsepower, larger capacity, better chassis. In the end, of course, it's all about higher speeds and better safety. That's exactly the philosophy of X-Bionic. Superior products, like the Bionic Energizer, aren't just replaced, rather they are constantly improved. The Swiss textile engineers needed months and months in the research laboratory together with performance athletes. They focused mostly on the athlete, not on the product. How can they better support athletes in their endeavours? In the end, you could hardly recognize the Bionic Energizer anymore: a much larger 3D-BionicSphere System, newly defined ventilation chambers, better joint protection.

Skin Nodor
Skin Nodor is a climate-activated nano-filament which incorporates an inorganic, bacteriostatic ingredient in its interior. The gradual release of ions, which are activated by body heat, is the key to the effectiveness of Skin Nodor. These ions inhibit the growth of microorganisms rather than eliminating them outright, thus preserving the delicate balance of the skin‘s ecosystem. In other words, Skin Nodor is bacteriostatic (i.e. it inhibits bacterial growth), rather than bactericidal (bacteria-killing). Therefore, allergic reactions do not occur. Skin Nodor is especially soft and breathable and provides superior fit.

A lightweight, pH neutral, hypoallergenic fibre. Reduces the accumulation of germs and bacteria.

3D-Bionic Sphere System
Leaves residual moisture on the skin that the body does not interpret as dampness. We have no sensors for sweat. We can only perceive sweat mechanically once drops form and begin to trickle down. Only at that point do we register “wet”. Sweat Traps absorb this moisture before it is felt, drawing it away to be evaporated and disposing of it through thermal dynamics. Only a thin film of moisture remains on the skin. Cooling is of course not possible without moisture.

X-Impact Technology
The unique X-Impact Technology by X-Bionic creates a perceptible pressure all over. The sensation stimulates body awareness without restricting freedom of movement or affecting fit. You move more precisely and more effectively, and your muscle performance improves.

Sweat Traps
Trap perspiration before you start to feel it. Wick perspiration away so it can evaporate using heat dynamics. A film of perspiration – too thin to be noticeable – is left behind to cool the skin.

Sits comfortably with good compression at the same time. Shirt looks nice even though it is under your sportswear. Works well beyond expectations. In heat (intensive indoor sports and fitness) good sweat decreases and breathes perfectly, body does not get overheated, while running outside in the cooler mornings it stays nice and warm. Shirt does what it should do. I had several other compression shirts but this one is my preference because of the good heat regulation and sweat reduction.

Zit heerlijk comfortabel met tegelijkertijd goede compressie. Shirt ziet er (ondanks het onder je sportkleding zit) ook leuk uit. Functioneert boven verwachting goed. Bij hitte (intensieve zaalsport en fitness) neemt het goed zweet af en ademt perfect, lichaam raakt nietover verhit, bij buiten rennen in de wat koelere ochtenden blijft het lekker warm allemaal. Shirt doet dus wat het hoort te doen. Heb diverse andere compressie shirt gehad maar deze heeft toch mijn voorkeur door de goede hitte regulatie en zweet afname.

Have already worn some functional clothes. This is by far the best.

Hab schon einige Funktionswäsche getragen. Dies ist mit Abstand die beste.
