Silva Trail Runner Free 2 Ultra

"The Trail Runner Free 2 Ultra by Silva is an ideal headlamp for all running enthusiasts who are looking for comfort and performance. This headlamp is specially designed for runners and offers optimized light beam technology that is tailored to the needs of running. Thanks to the Free Technology, there are no interfering cables, which guarantees a pleasant and uncomplicated user experience. The Trail Runner Free 2 Ultra comes with a rechargeable 4.0 Ah (14.8 Wh) battery and a hybrid battery compartment that can hold both the Silva Hybrid-battery pack and 3 x AAA batteries for maximum flexibility."
"The headlamp offers an impressive light output of up to 550 lumens, made possible by a powerful chiller that optimizes cooling. With Silva Intelligent Light technology, runners benefit from a unique combination of a high beam and a wide floodlight, resulting in less head movement and better control. This improves balance, reduces fatigue and enables higher speeds when running."
"Weighing just 61 grams (without battery), the Trail Runner Free 2 Ultra is lightweight and perfectly balanced. The soft, adjustable headband with a silicone band on the inside ensures that the lamp sits securely and comfortably while running. The battery can either be worn on the headband or kept warm in the pocket with a textile extension cable to extend the battery life. The waterproof feature of the lamp also makes it a reliable companion in any weather"
