APEX, the fibre helmet of SUOMY, has a racing shape but at the same time it grants the comfort, that only a high quality helmet can give. SHELL in three sizes (XS-M, L-XL and 2XL-3XL) hand made. The new material is a mix of carbon and aramidic fabric. INTERNAL POLYSTYRENE in three sizes (XS-M, L-XL and 2XL-3XL). The special shape and construction in different density increases mechanical resistance in the event of accidental shock. SHIELD thermoformed froma flat sheet. Each shield is a one-of-a-kind piece with unequalled optical features and mechanical resistance. Thanks to this process, the face shield is anti scratch and anti fog and there is no need to use additional lenses on the visor. The D-RING RETENTION SYSTEM has been designed and patented by Suomy. Insert the free side of the strap in the rings. Pull the end until the strap presses firmly against the jaw. After this operation, it should not be possible to remove the helmet. Verify that by grabbing it from the back and rotating it to the front it cannot be removed and it is fixed to the head. If the helmet tends to come off or rotates freely, tighten the strap again until the right pressure is obtained and repeat test. If after repeating the test you are not able to efficiently tighten the retention system, do not use the helmet. Only after checking the correct tension of the strap, fix the free end locking it with the automatic stud to the release tab. The automatic stud is necessary only to fix the free end of the strap to prevent it from flapping while riding. Fixing the release button does not assure that the helmet is correctly in position and properly fastened: the correct locking of the strap must be verified exclusively following the above paragraphs. To release the retention system, release the automatic stud button and pull the release tab to loosen the closure. Slide out the free end of the strap from the \"D Rings\". Use the release tab only to remove the helmet! Never release this tab while riding. APEX is homologated as per the following rules: ECE 22-05, DOT, QAS, JIS, INMETRO NBR 7471 CHEEK PADS completely removable and washable, in different thicknesses for a complete customization of the product. INTERNAL SHELL completely removable and washable, in different thicknesses for a complete customization of the product. The internal removable shell has been studied for an uniform stand on the head. The visible channels allow the air flow to check the temperature in teh internal part of teh helmet and to let off the hot air through the back part. INNER (cheek pads and inner liner) are completely in fabric COOLMAX® ACTIVE with treatment INTERPOWER: Wicks sweat away from the body. Keeps the user fresh, dry and comfortable. Lightweight, soft and breathable fabric. Performance verified and certified by ADVANSA. REMOVABLE NOSE PROTECTOR The SHELL is a polystyrene with channels for inside air flows. In the front part there is a AIR VENTILATION with on/off system, which gets the internal helmet ventilation. On the chin part there is an adjustable AIR VENTILATION. SPOILER AND BACK AIR VENTILATION: produced in polycarbonate , it has been studied and tested in wind tunnel, so that the point of detachment of the aerodynamic flow is shifted as far away as possible from the shell. This results in less turbulence and therefore fewer vibrations on the helmet itself. weight: ca. 1250 ± 50grNote Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it is shown differently.
