Trekchick, There’s really no need to wait for a powder day before you install your Pow Tales. Once installed, they will just be there whenever you find that stash waiting for you. No, groping around in your gear bag looking for them. No forgetting to put them on, and no hassle engaging or disengaging them. I’ve had a set on my boots since this season began and they don’t get hit by my skis. They don’t deploy unintentionally, and they don’t need any special care or feeding. They’re just there when you need them.
