> supposedly makes you > not buried as deep Not just that, but if you start out deep it should make you "float" to the top while the avalanche is in motion, at least for some types of avalanches. Put small and large pebbles in a jar and keep shaking it, the larger pebbles will rise to the top. Same principle.
