http://www.sailandski.co.uk/acatalog/Red_Womens_Total_Impact_Shorts_2011.htmli have a pair of these although i haven't worn them for a while. they're padded at the bum aswell, but feels quite hard, so i took a triangular piece of padding and sewed it onto the tailbone section. i wore these when i kept on falling on my hips/arse
(the hip padding is especially good). i did have skin colour ones which were padded at hips and tailbone, but with me being crazy and all, they didn't do much good (also my leg/arse section was getting a battering and started to get inflamed/painful to walk). in the video, i was just wearing some cheap ones i got for learning to snowboard, its just about a 1cm layer of hardish foam at the hips bum and tailbone, it gives a bit of protection for when i fall, but not for complete wipeouts, its very light padding. Coach made me do 2sal in my new boots (which is far from consistent) and my feet just happened to slip sideways away from me....landing on ur hip is not fun, even with protection
so yeah, i usually wear my cheap pair for jumps, unless i'm learning a new one which i know i'm gonna wipeout on, in which case i'll wear the gel shorts
