See, I’m not sure how much of it is real and how much is in my head… With my old Strike, it felt a bit more enclosing and I definately blamed it for feeling out of breath sometimes. My newer Urge has a lot more vents and is just generally more open at the front, and I don’t get that feeling at all. But logically I doubt it really makes that much difference, there’s a massive hole at the top and bottom after all.
Big fan of my Urge Down-o-matic incidentally- it’s light, not too expensive, well made and seriously well vented. They do an enduro-specific fullface with a big mouth vent, which could be even better, but is more expensive.
