In reply to UKC/UKH Gear:
Thanks for the (for me) timely review. Just got back from the Frankenjura where I took a 7m fall while attempting to clip a high 2nd bolt. My partner caught me perfectly, but I inverted and my head made contact with a rock on the ground. The cheapo Decathlon helmet did its job, no damage done, but I‘ll be looking around for a new one.
Wear those helmets, folks!
