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.

For the price, this is an ok product. Bought 3 to give as gifts, and noticed the compass has to be set just so to get a good reading, and even then one of the 3 pointed slightly off north. Clip and thermometer are fine. A good gadget for local hiking.

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.
