Of course we’re always careful with our kit, but even we can’t help the weather… nor can we help wanting to venture out in some of the more challenging elements.

Prism is our gnarliest head torch, designed to light the way for all-weather warriors.

An aluminium body makes Prism incredibly durable. Dust proof, drop proof to 2 metres and waterproof to 1 metre of submersion, it’s built for reliability in hostile environments and challenging adventures. Think mountaineering, climbing, kayaking or trail running. Prism is lightweight and has a central overhead strap to keep it stable on your head, this makes it popular amongst mountain marathoners and fast and light adventurers.

Prism’s LED bulb burns for between 3 – 14 hours between charges, depending on the brightness setting. The light modes range from 250 – 80 lumens and you’ve got a 10 second 400 lumen boost mode for when you’re trail finding or need to see every lock, stock and barrel in sight. Prism’s 180˚ projection angle lets you point that sunbeam whichever way you want.

You shift through the settings with a single button, which means minimum faffing about when you change environment or activity. Don’t worry, you can keep your gloves on to operate it, so you won’t have to expose your hands to the elements!

Prism is rechargeable, with a micro USB input that lets you plug into a solar panel, car, laptop, Lampray light, battery pack… the possibilities are endless.
