My wife just had her first backpacking experience and well I love getting nice and funky for 4-5 days, she was a little uncomfortable by the end of the trip with the smell and dirtiness especially down there. She asked if next time if she could bring baby powder along to help. Of course I said NO I"M NOT CARRYING ANY EXTRA WEIGHT!!! But in all seriousness is there any risk (I'm thinking mostly smell related) with using/bringing a small bottle of baby powder? I asked her if she would prefer something else, but that seemed like it would work for multiple things for her so whatever she wants is fine with me - I just want to be sure its safe and see if maybe there are some better options out there from more experienced female backpackers. Is it safe to leave out at night or should it go in the bear bag? Thanks in advance.
