What we like:

Purpose-built design for climbing at night.

What we don’t:

Heavy and bulky.

If you’ve tried to climb in the dark and you’ve realized that it’s not simple. The world shrinks to a single square foot the front of you and finding a most effective way can be quite difficult. A good headlamp will create a night and day distinction (no joke intended) for instance, this Black Diamond Onsight 375 is specifically designed for this purpose. The most notable feature is the two simple-to-twist beams. In climbing mode, you receive 300 lumens of light dispersed to illuminate the area ahead of you, and route-finder mode gives you an 375-lumen long-distance beam to help you find anchors and the path ahead. The operation is surprisingly simple using a single button to turn on the lamp and tap the technology either side to toggle between modes.

Alongside the dual beam design and the other features, this new Onsight 375 is well thought to meet the needs of climbers. As with many of the Black Diamond’s new offerings, this one comes with rechargeable batteries which can be exchanged to three AAAs, which is a great alternative to carry when you’re traveling for a long period of time at the same time. The IP67 waterproof rating means that it’s completely submersible and dustproof (great for long-lasting use) Additionally, the SOS mode can be useful in an emergency. However, at 4.75 pounds, the BD is larger and heavier than the majority of headlamps as climbers ourselves, we’re not sure whether it’s worth the cost for the additional features. If you’re planning to use it for climb at night (that was the strategy of Tommy Caldwell in The Dawn Wall, after all) If you’re planning to climb at night, the Onsight 375 is a great small-scale piece of equipment at a moderate price, but we’ll go to the more lightweight options to use in emergency situations.
