Technical FEATURES
Enhance your training and unleash your true athletic potential with performance sportswear that performs when you need it to. Featuring our patented Neuromuscular Performance System and flexible skeleton structures, the Reflex Performance Shorts proactively stabilise your quads and hamstrings during activity. Feel empowered with full muscular control even when you’re pushed to the limit and prevent over-extension with O+A’s revolutionary performance sportswear design.
Our Performance Shorts incorporate 14 sensory nodes that interact with the skin over the quads and hamstrings, stimulating tactile mechanoreceptors and amplifying afferent feedback to your nervous system. Using your innate ‘sixth sense’ of proprioception, you can consciously connect with every movement, enhance awareness, improve muscle recruitment patterns and facilitate powerful activation when it’s needed most.
Performance muscle-mapped compression around your quads and hamstrings works to reduce muscle vibration and keep you locked in during high-impact activity. This decreases the activation required for damping and streamlines proprioceptive feedback to your nervous system, effectively enhancing muscle and movement efficiency. Recovery time is reduced and muscle damage limited, leaving you ready to put on the afterburners to achieve your athletic goals.
Screen-printed silicone cuffs around the thighs combined with an elasticated waistband provide a close, comfortable fit, keeping the shorts secure and held in place whatever activity you throw at them.
TARGET MUSCLE GROUPS
Targeting your quads and hamstrings, our Performance Shorts are anatomically engineered to help you achieve your athletic goals with confidence and style.
TARGETED SUPPORT
A network of flexible skeleton structures supports the quads and hamstrings for improved muscle control and movement stability.
MOVEMENT CONSCIOUSNESS
14 sensory nodes interact with skin over the quads and hamstrings, enhancing proprioceptive feedback to improve body awareness.
MUSCLE-MAPPED COMPRESSION
Muscle-mapped compression over the quads and hamstrings works to reduce muscle vibration and support efficient movement.
THERMAL REGULATION
Moisture-wicking fabrics and body-mapped ventilation help control temperature and allow your skin to breathe.


Engineered moisture management and breathability draws sweat away from your skin to keep you feeling dry.

Nylon Tactel™ has a premium soft feel that is gentle on the skin and dries quickly.

Body-mapped ventilation facilitates moisture wicking, allowing your skin to breathe.

A tight body-hugging fit to provide performance-level compression and minimise muscle vibration.

Silicone cuffs keep the garment and flexible skeleton support in position as you train.

Sensory nodes interact with the skin to maximise proprioceptive feedback and promote efficient movement.

Anatomically positioned flexible skeleton structures support and stabilise the body during movement.


fit and care
Step into the shorts and align the skeleton along the natural path of your quad and hamstring muscles, positioning the sensory nodes as per the graphic. DO NOT forcefully pull the garment from the top as this will risk tearing the specialist fabric.
