Collar: 2 x 1 mm
The collar is made of Glide Skin with a thickness of 2 x 1mm: a double layer of Glide Skin on the skin in order to prevent water ingress, allowing the collar to stick to your neck as it were, which moves along as a result, thus preventing chafing. The closure on the rear is reversed*. We are the only wetsuit brand to have selected this; the reason being that, in the unlikely event the suit is closed incorrectly, only the soft Velcro will touch the skin. We are fully convinced that our wetsuits (all models) are free of chafing.
Shoulders and armpits: 1.5mm
The shoulders and armpit section are more or less the most important! We have created the arms as well as the armpit section using the most flexible material available on the market. The super smooth Glide Skin on the outside, aided by a lining of pre-stretched 4-way Super Stretch, ensures that you have maximum freedom of movement. This also means that, when removing the wetsuit, there is no resistance at all and you are out of the wetsuit in no time, which ensures minimal changeover time.
Grip panels: 2.5mm
The MACH4S is equipped with grip panels on the inside of the forearms and on the shin. The ridges in the grip panels ensure low water turbulence, creating better propulsion around the forearms and lower legs. This ensures a stronger arm and leg stroke, and therefore a more effective swimming stroke.
Upper chest panel: 2.5mm
This 2.5mm thick upper chest panel enables you to lie in the water without a hollow back, allowing you to generate an effective thrust from the hips with your leg stroke. This panel also ensures extra freedom of movement and space during your recovery stroke. This is clearly noticeable, especially over long distances.
Main body panel: 5mm
The 5mm thick main chest panel ensures buoyancy, which makes you go faster and gives you a better lying position in the water, delaying the onset of fatigue. The ITU and ETU, as well as Ironman and Challenge, have imposed a maximum thickness of 5mm. By using our 44 cell rubber we have further increased the airflow inside. This way, we do not exceed the thickness but generate even more buoyancy.
Body panel stability
The body panel is made in such a way that it ensures you will lie tightly in the water tightly, the compression ensures a stable position in the water, as well as less body volume, which means lower resistance. The lining on the inside is a 4-WAY Super Stretch, which is, however, a little less stretchable due to the aforementioned, and especially because this prevents water from accumulating around the torso in the event that water enters the wetsuit – the latter would make the suit, and you, heavier, causing you to lie lower in the water, and reducing speed.
Stability panels: 5mm for men, 4mm for women
The so-called stability panels on the hips are new in the MACH4S. These stability panels help you adopt the ideal swimming position in the water (for less experienced swimmers) or support this position (advanced swimmers). These 5mm panels and the 2.5mm thick upper chest panel enable you to lie in the water without a hollow back, allowing you to generate an effective thrust from the hips with your leg stroke.
From the upper leg to above the knee: 5mm
In order to prevent the legs from sinking down especially over longer distances, the upper leg panels are 5mm thick, and the embossed V shapes here also ensure acceleration.
Knee panels: 2.5mm
The front as well as the back of the knee is equipped with 2.5mm Glide Skin 4-way Super Stretch, as this simplifies the leg stroke.
Lower leg Aqua grip panel: 3.5mm
The MACH4S is equipped with Aqua grip panels on the shin. The ridges in the grip panels ensure low water turbulence, creating better propulsion around the forearms and lower legs. This ensures a stronger arm and leg stroke and therefore a more effective swimming stroke.
Calf panel: 2.5mm
The calf panel is equipped on the inside with our unique 4-way pre-stretched Super Stretch, which together with the Glide Skin on the outside and the obliquely cut opening, makes it possible to remove the wetsuit without any effort at all.
Back leg panel: 3.5mm
With a thickness of 3.5mm, this panel makes it possible to achieve a perfect water position. If it were thicker, it would cause a hollow back and if it were thinner it would cause too low a position in the water.
Back panels: 3.5mm
The back panels are not only there in order to ensure extra buoyancy, but they are an extension of the shoulders as well. This is why 3.5mm was selected with 4-way Super Stretch lining in order to obtain more freedom of movement as well as the additional buoyancy.
The zips have a metal runner, which ensures gradual opening and closing. Following a survey held among our Dare2Tri Int followers, we decided to have the zip closing from the bottom up. The vast majority indicated this is to be preferred to a top to bottom zip.
