Two safety features in one, plus a carabiner marked with the A.T. monogram. One side is a mini-compass (a useful planning tool with or without a lifesaving map), while the other gives you the current air temperature more precisely than "feels like...."
The carabiner is now royal blue, not the green in the image.

Do not like the color. Not a fan of blue. On the A T website it shows the item as green. I'm sure it functions well. Will give it to a fellow hiker.
