lightweight, snug fitting, body cooling strap-vest. Lasts anywhere from a couple hours to five hours depending on how many freeze-inserts you place in it.
hahaha. I dunno about that. That thing will not be light.
Is this a joke? Like a backpack of lead.
I think that would make me perspire more!
It weighs only 1lb, 5oz, even the heaviest model is only 3lbs, the weight addition is as significant as adding a couple extra water bottles.
I made one from a dry bag, a backpack from a thrift store and I just put a 5 pound bag of ice in it, of course I don't ride my bike with it, and mine was an original idea.
