If good things come in small packages, then this must be pretty good. Powered by a single AA battery, the S-Flex is a simple headtorch from Mammut which is all you need to find your way around your tent, to the campsite loo or that elusive Snickers at the bottom of your pack.
Weighing in at 22g (without battery) it would be ideal for slinging in to a pocket and forgetting about until you need it. With no bells or whistles, it comes supplied with an elasticated headband with a sliding toggle for fit.
Like the Mammut Burny we tested a while back, the S-Flex needs a double-click to turn on which should help avoid accidental battery draining.
Featuring a 25-Lumen, 40-degree spread beam it is plenty bright enough to read a book, but this isn’t a headtorch for following dangerous paths with.
It has 2 settings – bright and brighter – and then a red constant or red flashing option which can be used on the back of your head so people can keep track of you in the dark.
