Yes, there’s a difference in ‘Waterproof’ and ‘Water Resistant’. However, I have worn ‘waterproof’ things before that didn’t keep water out for very long. Probably because it also boasted that it was ‘breathable AND waterproof’. Seems like an oxymoron to me. However, if I’m going out in the rain, I’m wanting something waterproof over water resistant, no doubt. If you are the type that suddenly melts into a puddle of smoldering goo when exposed to moisture, you probably want waterproof, too.
