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 & 2XL-3XL) hand made. The new material is a mix of carbon & aramidic fabric. INTERNAL POLYSTYRENE in three sizes (XS-M, L-XL & 2XL-3XL). The special shape & 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 & mechanical resistance. Thanks to this process, the face shield is anti scratch & anti fog & there is no need to use additional lenses on the visor. The D-RING RETENTION SYSTEM has been designed & 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 & rotating it to the front it cannot be removed & 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 & 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 & 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 & 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 & washable, in different thicknesses for a complete customization of the product. INTERNAL SHELL completely removable & 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 & to let off the hot air through the back part. INNER (cheek pads & inner liner) are completely in fabric COOLMAX® ACTIVE with treatment INTERPOWER: Wicks sweat away from the body. Keeps the user fresh, dry & comfortable. Lightweight, soft & breathable fabric. Performance verified & 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 & BACK AIR VENTILATION: produced in polycarbonate, it has been studied & 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 & therefore fewer vibrations on the helmet itself. weight: ca. 1250 ± 50gr Note 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.
