Troy Lee`s D4 helmet made of composite material
Many helmets claim to be the icon, the legend, the undisputed champion - but there is only one truth.
The Daytona, D2 and D3 helmet series changed the entire state of affairs and redefined the marriage of technology, safety and artistic design.
This idea is reborn with the introduction of the D4 Carbon and Composite and will once again... change everything.
highlights
- Aerospace grade fiberglass outer shell
- Equipped with the MIPS® Brain Protection System - a low-friction layer integrated into the helmet that reduces rotational movement on the brain in the event of an angled impact on the head
- Ventilation channels and head pads work in unison to promote airflow through the helmet
- Lightweight titanium double D-rings and hardware
- Extended EPS layer on the lower edge of the helmet to prevent collarbone injuries
- Innovative tear-off helmet shield screws
- Molded polycarbonate around vents and exposed EPS increase strength and durability
- Washable XT2 3D cheek pads and X-Static/XT2 head pads with quick release ensure an optimal fit
- Includes TLD drawstring helmet bag to keep your helmet looking good

Technologies used
In this chapter we explain the technologies that the manufacturer uses in this product.
MIPS
The MIPS® safety system was developed to provide additional protection for helmets in numerous accidents. In certain impact situations, the MIPS system can reduce dangerous forces that might otherwise be transmitted to the helmet wearer's head.
1. Conventional helmets are designed and tested for a straight impact. In most cases, however, the impact is at an angle, which can cause rotational movements for the head.
2. This rotational movement can cause brain injury.
3. The low-friction shell is designed to help reduce rotational movement of the head in certain cases of angled impact.
Straight impact - oblique impact
The brain is typically more sensitive to rotational movement than linear movement because it has a shear strength similar to that of water or gel. When rotational movement causes different parts of the brain to move at different times, the tissues can be stretched, causing concussions or other brain injuries.
Rotational motion is a common cause of concussion and more serious brain injury from an oblique impact to the head. The MIPS system consists of a low-friction shell that is fixed inside the helmet. The low-friction shell is designed to slide slightly inside the helmet in the event of an accident, allowing forces to be directed away from the head. It is said to help reduce the risk of brain injuries.
Most conventional helmets are designed for a straight impact, but in most cases the impact is at an angle. The low-friction shell can reduce the rotational forces of an oblique impact.
Security system with the brain as a model
Unlike conventional helmets, which are primarily designed and tested for a straight impact, the low-friction shell of the MIPS system mimics the brain's own protection system against rotational movement. The cerebrospinal fluid is our natural defense system that allows the brain to move offset to the skull.
