I use a North Face chamelion. A bit smaller than your packbut it works for me.
North Face logo at top of pack, I covered it with a sticker, otherwise I was
tempted to put a "South Face" logo on the bottom of the pack.
I don't dig the company logo trend on clothing and gear.
A wheelchair guy hailed me at a grocery store.
"Hey LL Bean can you reach that upper shelf for me"
I'd rather be called F-face, it's less pretentious.
