超輕鈦哨子

I was worried it would be too tiny to hold onto, but the titanium feels solid in your hand and the sound cuts through wind like nothing else. Even after getting rained on, it still works perfectly.

I've been using this whistle on my daily trail runs and the sound really cuts through the wind. The titanium construction feels solid but I honestly forget it's even clipped onto my pack.

Finally got around to testing it on a trail run, and the pitch is sharp enough to cut through wind noise. The titanium feels genuinely indestructible, though I wish it came with a lanyard for easier access. At this weight, I'll be keeping it on my pack indefinitely.
