I took this thing with me on a surf trip to Costa Rica and it came in so handy! I took the boat ride out to Witches Rock and my leash string popped..All I had in the boat was flip-flops and a towel!Thank god I had this thing in my backpack! I used the lanyard as a string and was back in the line up in 5 minuets. The little leash hook help my pruned fingers thread it too.
