The Nanuk Nano 310 is excellent for a small wallet, credit cards and/or other small valuables. I has a convenient wrist strap and is available in a variety of bright colors. I really love the lime color because it’s very easy to see, should it fall into the water. This case is pretty much a must for anyone wishing to better protect their small valuables from water and the elements. The build quality is exceptional and the latching mechanism latches securely but is easy to operate.
