That Parachute is seriously light! Hadn’t noticed that.
Urge Down-o-matic isn’t so light but it’s a traditional, full-on dh helmet that just happens to be well vented and lighter than many. (mine is just over 900g- less than claimed but I threw away the stupid round rubber thing in the visor as it adds nothing but logos and weight) But the venting, though good, won’t be a patch on the parachute- I still consider it downhill only.
The Fixer didn’t fit me but it seems good. I have their Bushwhacker XC hat and what I really like is the compactness, it just seems like a really good idea- reduces weight and all that but also reduces some impacts and rotational forces. Though the fit is a bit weird on that too.
Totally agree on weight being a detriment in crashes btw, we don’t talk about it much in pushbikes but it’s well remarked on in motorbikes- significantly increases forces on the spine but also increases dwell time of peak force on the brain, which is believed to make a big difference to damage caused by high loads.
