Paranoid about your backpack doing a disappearing act? Meet the Matador BetaLock™ ($30), the carabiner that moonlights as a tiny, key-operated fortress. Crafted from aircraft-grade aluminium (because your gym bag deserves aerospace engineering), this gadget lets you clip your stuff together like a regular carabiner. But here’s the James Bond bit: whip out the included keys, and BAM! It locks, deterring those grab-and-go opportunists.

Finally, a lock that isn’t a cumbersome, uninspired paperweight. The BetaLock™ is lightweight, comes in various colours (for identifying your loot, naturally), and is even TSA approved, so airport security won’t get their knickers in a twist. The most effective lock is the one you actually have with you, and since this one clips onto everything, you’ve got no excuse. Now you can secure your gear with a smug sense of preparedness.
