well its quite simple really, it weights your weaker leg you pop off of, my left, so that when you pop the weight is to within grams of the other legs strength just by weight causing your skis to get "MAD" pop, that is a scientific term by the way. other than that they are a good place for keys, and chapstick, I dunno if you've ever landed on your keys but they can stab quite easily.
as for the kid that got way worked up, I know why airblaster was founded I also know as much as most consumers can that airblasters product is made from recycled/left over materials, and it is also a company that pays their workers fair wages, which goes above and beyond most major ski or snowboard apparel corporations. so if I'm gonna blow my money on stupid shit at least I'm helping pablo eat. so while I'm "repping" some stupid shit that represents the idea of fun, you should watch your blood pressure, you might burst a vessel getting worked up over a thread that was supposed to pass the time until snow falls.
