That being said I love my alpinestars 2 piece to bits and the zipper seems to be very good quality on mine, with both the road and track pants, brought it all second hand and the jacket must be up to about 300 uses with me and going well. I borrowed a mates Dainese jacket when I first got my L's and I found the alpinestars to be more comfortable, but I'd probably rather crash in Dianese, that leather was insanely thick!
