I went through the minefield when i first started riding, even the idiot at heine gerrike didnt have a clue. I said im a 48 chest so he gave me a size 48 leathers, No chance, turns out you have to add 10 the what your chest is and then your right. so i needed a size 58. Went elsewhere and found that out. you'd have thought a salkeman in a motorbike shop to have known though
