Summer Sale Ends In
Okay, so I’ve been trying to shave ounces off my pack forever. My old setup was a mini headlamp and then some clunky lantern for camp. This CapLight? It replaced both. Seriously, it just clips on my Smartwater bottle at night and boom, I got a tent lantern. Then I pull it off, hit the trail, and it’s a perfectly capable flashlight. The warm white is great for chill evenings. Best new piece of gear I bought this year, no contest. Wish I’d found it sooner.
This little light is awesome for camping. I use the lantern mode every single night to read in my tent, and it gives off such a nice, soft glow. The flashlight part is strong enough to walk to the bathroom in the dark. My only, tiny, complaint is that the clip can feel a little loose on certain older water bottles I have. It hasn't fallen off or anything, but I just wish it was a super snug fit on absolutely everything. Still totally recommend.
We took this camping with the family last month and everyone was obsessed. Turning a plain water bottle into a glowing lantern was such a neat trick. My son, Leo, kept asking to "turn on the bottle light." It's so small, I just toss it in my gear bag and forget it's there until we need it. Bright enough for inside the tent for sure.
J'adore cette petite lampe ! Tellement légère, elle se glisse partout. Pour nos bivouacs, c'est devenu indispensable. La lumière diffusée par la bouteille crée une ambiance vraiment agréable le soir. Plus besoin de trimballer une lanterne lourde. C'est parfait.
Die CapLight ist eine nette Idee, wirklich. Und sehr leicht. Für das Lesen im Zelt ist das Licht okay, wenn es an der Flasche ist. Aber als richtige Taschenlampe ist es mir nicht hell genug. Für den Weg im Wald nachts wünsche ich mir mehr Power. Trotzdem, für den Notfall oder etwas sanftes Licht, ist es brauchbar.
