Enjoy the trail carefree with Oakley's DRT5 MTB helmet
Oakley's DRT5 was engineered, designed and tested by mountain bikers in close collaboration with three-time world downhill racer Greg Minnaar. You can absolutely rely on this helmet when it comes to mastering difficult descents safely.
highlights
- Goggle Stowage : The Oakley DRT5's rear foldable temple hooks provide space to securely stow goggles while riding or taking a break, and allow for unrestricted airflow inside the helmet
- BOA 360 Fit System: With its soft textile feel and highly elastic properties, the TX1 Lace System lies flat on the head and ensures seamless eyewear compatibility
- Sweat-wicking silicone strip: Absorbs sweat and wicks it away from your eyes, keeping your glasses streak-free
- Adjustable Visor: Includes six detents with over 60° of total adjustment, allowing riders to easily stow their goggles in a forward-facing position
- MIPS Integration: The MIPS Brain Protection System is a helmet-integrated, low-friction layer designed to minimize rotational movement of the head

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 motion than linear motion 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.
