Watching people run downhill after their rolling water bottle - gaining speed on snow- is funny until it happens to you. Try to catch the bottle without breaking your neck.

Karen is a great experimenter. To keep bottles from rolling downhill, through trial-and-error, she landed on thick rubber bands. Thank you, Karen!

The outer pockets of my day pack are too short for tall bottles. Lean forward to tie a boot lace and bottles fall out.

In the summer I use a CamelBak, 3-liter water system. Drink water as I hike. But the tube and bite valve freeze in the winter.

"I'm not going to re-clip your bottle," hiking partners say.

I don't blame them. For three years, I have been securing tea and water bottles with mitten clips. Through the handles. Mitten clips are designed to thwart kids. They frustrate adults, too.

Rubber bands hold bottles securely in outer pockets.
