The Petzl Vertigo has been primarily designed for ease of clipping in with the added bonus of having a locking key gate. This makes it ideal for Via Ferrata and kayaking applications where you need the safety of a locked gate yet want to open and secure it quickly.
My set of custom ear plugs arrived this week from the Paddleplugs team. I chose red plugs with a blue leash.
The images below show the moulds that were created (in pink) and the final set of leashed plugs.
