That's the biggest problem I find with any upper body armour, is that it continually rides up. I'm finding that I'm having to keep pulling it back down all the time throughout my ride.
I don't know why people keep saying that Dainese is women specific either. Maybe stick women with small breasts specific. But referring to heckler's better 1/2's comment about the squishing effect, I too can't wait to rip the suit off after a few hours. It's definitely constricting in the chest area and I'm not even large chested. I always thought Dainese was made for guys, or unisex at the best, but not women specific. Was I wrong?
I only read one person saying it was women specific.
Everyone else who commented on it just said it seems to be the best fitting armour, which arguably, it is.
It might just seem to work well with women who are smaller framed than most guys because Dainese is the closest, most ergonomic fitting armour on the market. For smaller riders, or less broad shouldered riders, this is going to translate to a better fit.
It sucks to be "swimming" in your armour. It can be bulky, uncomfortable, and it looks awful. Proper fit is the key.
Have any of the ladies tried heating up the plastic protection on the front of the Dainese to buy yourself a little more room? I bet a heat gun to warm the plastic up until it is maliable, followed by a blast of cold water would work well in getting a more personal fit.
