The multiple award-winning K-Pact shines with ventilation and fit: the Super Perforator Neoprene stocking provides noticeably better ventilation of the knee area even when the pad is worn in long uphills at the knee. The asymmetrical padding on the inside and outside of the knee protects the joint in case of lateral contact with frames or obstacles. The certified (EN 1621, Level 2) SAS-TEC pad on the front hardly needs any further description: the absorption properties of this pad are simply first-class. In this combination of Super Perforator Neoprene stocking and SAS-TEC Pad the K-Pact is an absolutely reliable and very good companion for the round on the home trails, bike park visits or high speed runs somewhere in the backcountry!Technologies:Super Perforator Neoprene:Very flexible, especially robust and above all very air permeable neoprene. Of course not to be compared with mesh material, but in terms of neoprene it is the most air permeable material ION currently uses. SAS-TEC Padding:SAS-TEC is an innovative, German manufacturer of particularly high-quality protectors. The company looks back on a long history in motorcycle protection equipment - and is ION's first choice when it comes to reliable safety. ION protectors therefore often use three-dimensionally shaped protection pads made of a viscoelastic foam with exceptionally high absorption properties.Power Aramid upper material in the knee area:Power Aramid is a synthetic fibre originally developed by DuPont. It is now used in a wide range of applications, e.g. bulletproof helmets, tyres and bowstrings. The material offers outstanding qualities in terms of tear and abrasion resistance. And is therefore perfectly suited for protectors. - Weight: 500 g - Size information: Size is normal - Fit: tight fit - protection zones: knee - type of protector: soft - carrier material: 35 % neoprene, 35 % polyurethane, 15 % polyamide, 8 % polyester, 7 % ethylene-vinyl acetate - delivery (quantity): in pairs
