Bens 30 is solid
Bens 30 is good for almost all occasions, but if you really go to serious mosquito country pack Bens 100, it's 95% vs 30% DEET. The 30 will be fine most of the time so don't fret, but I also suggest some mosquito nets, regardless of the DEET you have. The nets are a mechanical barrier that simply are better than any chemical and give the confidence the bugs cannot physically touch you or get in your eyes (the worst!). Buy this with confidence it is much better than anything you can get at your local drug store, OFF Deep Woods is 25% (readily available), but now OFF does make a 30% but most retailers do not carry it. A safe purchase.
