The thought of you travelling to and from work daily, stresses me out! 
TBH everytime I see someone with a big back pack...they get my attention, you can tell which ones are heading to work and which ones are not at that time in the morning, especially on my line as its a few stops from the city almost everyone is an office worker and dressed like that.
There's lots of converts, a black guy or a white English guy with no beard, office attire and a big gym bag and no one will look at you twice. TBH I feel more relaxed seeing a bearded man wearing traditional paki clothes....the 7/7 bombers pretended to be back packers.
