Krok is the Norwegian word for hook — simple, until it isn’t. Inside the spine sits a sealed tracker and a soft LED you can switch on from your phone, so whatever hangs from it is easy to find in the dark or on a crowded campsite.

The frame is machined from aluminium and the gate snaps shut with a firm click. The battery lasts a year between charges, and everything is sealed against rain, rivers and the bottom of a muddy bag. It’s made for gear, not for climbing.
