How to measure: For the most accurate fit, measure yourself in your underwear. Use a soft measuring tape and keep it snug but not tight. For chest measurements, measure around the fullest part of your bust. For waist, measure around the narrowest part. For hips, measure around the fullest part. For sports bras, measure your underbust directly under your bust where the band sits.

Ultra-bright and lightweight: 1500 lumens for a weight of only 145 g
Lighting for movement automatically adapts to ambient light:
- Wide, uniform beam so you can comfortably see up-close or at your feet
- Mixed beam (wide and focused) allows for proximity and distance vision for movement
- Three white lighting levels: MAX BURN TIME, STANDARD (better power/burn time balance), and MAX POWER
- Longer burn time, greater visual comfort, and less manual operation with REACTIVE LIGHTING® mode, which allows the light sensor to automatically adjust brightness and beam pattern, optimizing battery usage
- Minimum burn time of 5 hours in REACTIVE LIGHTING® mode (STANDARD level), built to power through long activities like trail running and ultra-running
- Red lighting, continuous or strobe, at the rear of the headlamp, and a separate button to quickly turn it on or off
Ergonomic:
- The battery pack is in the rear to distribute the weight of the headlamp over the entire head, making it balanced and comfortable to wear
- Thin and flexible front plate, to better adapt to different head shapes
- Quick and easy rear adjustment
- Additional top strap for optimal support
- Lithium-ion 3200 mAh battery, rechargeable with a type C USB port
- Spare battery available for long distance trail runs, or simply to switch out the battery when it dies (R1 battery available as an accessory)
- Battery charge indicator with five-level gauge for precise monitoring of the battery charge level
- Rechargeable R1 battery can be used as a spare battery to charge other devices, such as phones or watches
- LOCK function to avoid accidentally turning on the lamp during transit or storage, or to lock lighting settings during your activity
- Reflective headband to remain visible at night
- Storage pouch allows you to turn the headlamp into a lantern in STANDARD mode, or carry an additional battery
