Black Diamond Vipers – Review

So far this season I have just used the Black Diamond Vipers in an Alpine setting and they have been great to use, they fit easily on the pack, are light and very versatile. They are designed to be used with Android leashes, spring/waist leashes (and work superlatively as leashless tools) and with the large hole on the head clip onto your harness easily too. They have been comfortable in the hand to use as a Piolet and have performed well as general technical tools-simply brilliant!
