The Silva Trail Runner Free 2 Headlamp is designed for runners, offering comfort and optimal light for your needs. It utilizes 3 x AAA batteries (not included) and the Hybrid battery case, which also features a rear red safety light for enhanced visibility. The innovative 'Free Technology' integrates power cords into the headband, eliminating dangling wires and tangles for a hassle-free experience. This second-generation headlamp boasts optimized cooling, allowing it to produce up to 450 lumens (with AAA batteries) while remaining lightweight.Silva Intelligent Light technology is featured across the Trail Runner Free 2 series, providing a unique combination of a long-reach spotlight and a close-range floodlight. This dual-beam technology reduces head movement, improves control, enhances balance, lessens fatigue, and allows for higher speeds. Every detail has been considered for weight optimization, with the headlamp unit weighing only 61 grams (excluding batteries). It is perfectly balanced with smooth adjustments and a flat, soft, textile extension cord that resists tangling. The headband is soft yet firm, with an inner silicone strip to ensure it stays securely in place. The battery can be comfortably worn on the headband or kept warm in a pocket using the included textile extension cord. The large on/off button is glove-friendly and allows toggling between four brightness levels: maximum, medium, minimum, and a flashing safety light. A new 'Maximum Mode Indication' feature provides a short flash when transitioning from minimum to maximum mode, which is particularly useful when tired or in adverse weather conditions. The hybrid battery case can be positioned on the rear of the strap, placed inside a pocket, or rucksack, connected via the soft-touch extension cord. The headlamp is fully water-resistant.
