If you were only going to buy one head torch, the AK customer service heroes would recommend you get a Viper. Viper is reliable, rainproof, adaptable and compact, so we tend to have them in our cars/bags/jackets no matter where we’re off to.
Viper’s light sensor mode reacts to your environment and activity. Look up at the trail ahead and it will brighten up, when you peer at your map again it will switch to the sidelights so that you don’t dazzle yourself. This means you can focus on your activity and not your light settings and lets Viper operate at maximum efficiency.
..Read moreViper has 5 standard lighting modes, from the 15 lumen sidelights for reading in your tent to the 240 lumen high power, with a 115 metre beam distance for when you’re running on the trail. With burn times that range from 5 hours at maximum to 115 hours on low, Viper strikes the balance between burn time, beam distance and brightness – which is what makes it such an excellent all-rounder! The light unit itself tilts forward for navigating, reading or not blinding your mates around camp.
The removable and adjustable overhead strap helps you get a good, balanced fit, making Viper spot-on for more dynamic activites, and at just 95 grams it is light enough that you’ll forget you’re wearing it.
The Viper is simple to use, with 1 button on the top to shimmy through the standard light modes, and another to activate light sensor mode. The buttons are large enough for you to use them with your liner gloves on.
Viper has a water resistance rating of IPX6, so it’s rainproof but not submersible. It takes 3 x AAA batteries and is compatible with good quality alkaline, NiMh rechargeable or NiCd rechargeable batteries.
