Are these bags waterproof? 

In a word, no, but this waxed canvas is impregnated with Martexin wax at it's inception and with it's nice tight weave, paired with the bag's Diamond Ripstop lining you can rest assured that the bag will keep you sensitive cargo safe from the elements. Sorting out a rain cover might be advised for being out for extended time in torrential rain situations. 

Can I rewax?

Yes, we recommend either Martexin wax or Otter Wax, but there are other options.  Also, hit up the Google with 'How to rewax waxed canvas' and there are tutorials on how to do it; wax and heat is the gist of it.  Not too difficult and it brings that lustre finish back.
