I'm 6'3" and 220. the nitrous shorts are great. i have shoulder harnesses i use for long distance races but around the cans i use the nitrous shorts. they are so convenient since all you ever have to do is put on the bar which means when you come to shore all you have to do is snap the bar off and your done. this is especially nice if you are going to shore frequently. i give rides from the beach a lot...
