Gitti, I disagree a bit in that I think your pack is WAY too heavy if that is the weight without water.
Here's what you've packed:
Sleeping bag, gortex jacket, merino long sleeve, 3/4 pants, long pants, merino short sleeve, silk t shirt and lavalava to sleep in, 2 socks, 2 undies, 1 bra, light weight fleece. Shampoo/body bar, toothbrush and paste, sunblock/moisturiser, personal meds, sportsrub, first aid kit, sunhat, leggings, sandals, lace top( 120 gram luxury item for going out to dinner in), guidebook, camera charger, adaptor. The water, lunch and guide book will add another 1.5 kg. My pack is a Deuter 34 litre womens, weighs around 1.5 kg, sleeping bag weighs 500grams. I could take a silk liner instead???
I don't know what a lavalava is, but I'd drop the pajama outfit all together. Just sleep in your underwear like everyone else or let the merino or fleece do double duty as a sleep outfit.
Is your shampoo bar the Ligget's bar? If yes, it's small enough. If not, consider cutting it in half.
I'd be sure the toothpaste is a travel size.
You don't need sportsrub really. Or put a little in a smaller container.
You don't need a first aid kit in my opinion - just a couple of bandaids and a needle and a couple of alcohol wipes. Anything you need, you can buy on the road.
If you are taking a sunhat, why do you REALLY need sunscreen?
Leggings? Are those like long underwear? If yes, take them, if not dump them.
You won't need the lace top - people go to dinner in their travel clothes.
Your sleeping bag is heavy... Joe took a $39 lightweight fleece liner and was toasty.
Rethink it a bit?
Hope this helps.
My pack weighs in at 12 pounds right now without water.
You only need ONE change of clothes.
Good luck!
See you on the road.
Edited: Also, I promise you that once you're on the Camino, you will happily leave behind those things you don't need... there are free boxes all the way... people who pack too much. Cheaper to just dump it than ship it home.
