NTA 8776 standard: The Dutch looked at their speedy e-bikes hitting 25 to 28 mph (about 40 to 45 km/h, tested at 6.3 m/s) and said, "Yeah, we need stronger helmets." So they built a tougher test: Higher impact speeds Hits against flat surfaces and curb-like edges Extra coverage for temples and the back of your head (the spots you really dont want meeting asphalt.) Stress tests in heat, cold, rain, and UV (because weather can affect materials and therefore your safety)
If you're not getting bites in one spot, don't hesitate to move to a different location
Verdict If youre into futuristic looks, fully seam welded construction, minimalism, and a company that knows what theyre doing very well, the Ortlieb Commuter is the pack for you
8-pound test doesnt have a lot of wiggle room in regards to abrasion resistance, so I dont risk it
