This helmet is extra strong, with layers of laminated bamboo, glued together. Our internal tests have shown it is stronger than any other bicycle helmets on the market. See https://youtu.be/zmHL60UlI_o
Bamboo bends but does not break. Mekong Quilts produces very reliable bamboo helmets with an EVA liner of 3 different thickness’s (10-12-15mm) to adjust for various head sizes and comfort. The helmets have not been certified yet, this is under process.
The making of the helmets is all by hand and involves a dozen different steps, all by very skilled women workers. The bamboo workshops provide employment to 20 people who have thus roughly doubled their income.
