2 pairs of padded bike shorts. They're a bit large, hopefully that doesn't lead to horrible chafing that I've read about
2 pearl izumi bike jerseys
2 pairs of loose athletic shorts (covers awkward bike shorts so that I may walk around town comfortably)
2 pairs breathable wool socks
2 pairs underwear for sleeping, walking around. I will likely replace these during trip
2 t-shirts for walking around, also form a nice little pillow for sleeping. Also may replace these.
1 pair of biking gloves
1 breathable cap
Eureka Solitaire bivy tent w/rainfly
Compactable sleeping bag.
*Note: most nights I will try to stay with a host. This will probably be easier while in the east coast and midwest.
Small shaving kit
Comb (this was the hardest decision while packing)
Bike multi-tool w/allen keys
2 spare bike tubes
Patch kit w/double patches and extra glue
Small presta valve bike pump
Tire pressure gauge
a few books of my choosing *2016 edit: WHY would you bring heavy books???
portable camp stove
*Note: I will likely buy food every few days at supermarkets. I'm finding there is little room left in the panniers for bulk food.
