Your shelter seems confused.....hammock with rainfly etc and a bivy and tarp?
Do you need a lantern when you have a light on your bike. FYI I use a Petzl headlamp for everything.
IMHO you are taking far too many clothes....I wouldn't worry about what you wear to Church, but you can be very presentable in a pair of lightweight convertible trousers and a polyester top and a fleece or jacket.
I'd leave the U-lock at home.
As my later replies indicate, the rainfly on my hammock
is my tarp. It's cross listed for my own references.
Yes, I do need the lantern. My eyes are really sensitive to light and even on the dimmest setting the bike light is too much for reading for me. On its brightest setting the lantern doesn't bother me.
