I thought I was a light packer, but last night I put everything I am going to take into my 50 litre pack and it was heavy (25 lbs.) and full. Here is what I am taking for my 7 week trip starting the end of April, can I cut anything out?

2 short sleeve shirts
1 long sleeve shirt
1 sweater
1 small rain coat
2 pairs zip off pants
4 pairs of underwear
3 socks
1 pair of shoes
1 pair of sandals for beach and showers
travel towel
sleepsheet
shampoo/soap combo
toothpaste/brush
deodrant
electric razor
glasses
guidebook
passport
money
bank cards
small flashlight
airplane ticket
small day pack
camera/film
small journal

I thought I had it packed well, stuff rolled and seperated with small bags. I don’t want to go with a full pack weighing 25 lbs.
