Replaceable Petzl Dual Chinstrap for Vertex® та Strato® helmets

Allows the helmet chin strap to be modified or replaced.
Allows the wearer to change the tension of the chin strap to adapt the helmet to different conditions: working at height (EN 12492) or on the ground (EN 397).
For this purpose, the clip on the strap has two positions to suit these two types of use: 
- high strength, which limits the risk of losing the helmet in a fall;
- low strength, which limits the risk of strangulation if the helmet gets caught while the user is on the ground.
Compatible with Petzl VERTEX (2019 and later) and STRATO helmets.
Equipped with a side splitter for adjusting the strap length.
Available in two colours and an extended version. 

Features:
- Weight, g:  34 (1.2 oz)
- Materials: nylon, polycarbonate, high-strength polyester
