Yes, I suspect it would, but then the pressure inside the suit would squish you 
instead of the blast pressure outside the suit..the pressure isn't the issue so 
much as the rate of pressure change. 

Humans can withstand a lot higher pressures (deep free divers do it all the 
time) but the problem with a blast shockwave is that it happens over a few 
milliseconds.

Like coming to a stop from 160MPH with your brakes (cool, even I could do that) 
versus hitting the wall at Daytona (dead Dale)
