As I have said before, why mess around with glides and lubes when a pair of Under Armour boxer briefs works so well? That's the only way I'll hike after going from chafe city to no worries. People try to come up with all kinds of complicated ways to solve an already solved problem. Trust an experienced backpacker here, Under Armour (when the right style is worn) is like wearing nothing except you don't chafe your business. And this coming from someone who swore off anything but boxers when he was 14.
