With the Boa leash system, you get all the advantages of leashless tools, without the risk of dropping them! The ice axe leashes are a simple, lightweight way to connect your tools directly to your harness. The updated Boa system includes a separate tether for each tool, so you can use just one or both as necessary. To save weight, the large loops allow you to girth hitch the leashes directly to your tools, without requiring carabiners. The leashes are different colors so you can easily identify your right and left-hand tools. They can also be used to secure a piton hammer, camera, or even a backpack. True to Blue Ice tradition, the Boa leash system offers a compact, minimalist and versatile solution for your boldest alpine adventures..
