i like this product a lot
i bought it 3 years ago now use it like 10 weeks day in day out in the winter

on the safety side it has protectedc me fromquite a few crash, which , i guess would ve been bad without it

it has a good perspiration evaporation rate also, i sweat a lot when sporting and this is never a hindrance; when it s wet on you, it ll dry in a matters of 10 to 15 min once you took off your main jacket

but... for me there s a but: the collar is made of a neoprene thingy and to my mind, an neck it goes up to high, giving me skin irritations there around the neck...

nothing too worrying to other potential user, i turn the collar inside the back and then it goes under the top of my 1st layer; which, in turn, leaves me WITHOUT neck skin problems and without any disconfort

all in all if you re in the maket for such a protection i find it a good buy!
