I think you are probably going to be trying out ALL possible types of undies in your quest to find what works for YOU. If you are active, and packing, I think you might be best off with snug pouch-type briefs or a jock. Boxers are comfortable, but not ideal for packing, so they work best if you are wearing baggy pants (sans package) or just hanging out at home. Boxer briefs have a nice feel, but for me the legs tend to ride up and get all bunchy, plus they do not hold a packer in place unless you are sitting still. I second the vote for the Andrew Christian line that has a pouch, although they can make me look a bit more endowed than I wish... The same is true with any jockstrap, since it supports your package a little high and tight. The jockbriefs are a nice feel, but not so widely available. My best advice is to buy ONE of something, and put it through a good test before stocking up. I have spent more money than I care to believe on finding the perfect underwear, but a guy's got to be comfortable, right?
