I weighed my baggage and it is already more than 10% of my weight, that doesn't include yet the shampoo, soap, shoes, mobilephone and the charger. Since i will be taking my journey in the middle of August maybe it is not a good idea to take a fleece jacket. Is there an area along Camino Fances that would require a fleece jacket in August? Maybe a long sleeve shirt with a rain coat would be enough if ever it gets chilly? Anybody out there who had their camino in August?
I think seriously considering what you can do without is a worthwhile exercise not only because it can lead to a lighter pack, but also you get to know yourself better when everything is up for consideration to be left behind. And then for everything essential, a question can be asked, is each essential item the lightest it can be? I did not bring shampoo, but washed my hair with soap. If that is unacceptable, just bring a small traveler's tube of shampoo, as previously suggested. There are lighter, more compact alternatives to polar fleece, e.g. the Patagonia Nanopuff, which provides an amazing comfort range, takes up almost no room in the pack, and weighs very little. Many commenters are mentioning snacks and lunch. Only a couple times in the Meseta did I pack a lunch or a snack. Almost everywhere on the Camino there are cheap lunch and snack options, with no need to be hauling extra food with you. I think the pack itself should be light and comfortable. My latest pack, Hyperlite Mountain Gear 2400 Windrider Pack fits the bill perfectly. I took a 2 pound down sleeping bag with me, a total waste of space and weight -- a sleeping bag liner was all I needed. My clothes were all lightweight and quick drying, e.g. Lululemon long sleeve shirts, REI quick drying pants. I wish I had only brought one change of clothes instead of two. I used by smart phone with a blue tooth connected, very lightweight keyboard for blogging. That worked well. I really wish I had not bothered with the
Brierley Guide Book or any other guide book. the arrows are clear, and usually the towns are close, accommodations self-evident.
I hope you are not counting your hiking shoes as part of your weight. I used a lightweight pair of rubber slippers (flip-flops in the vernacular of the rest of the English speaking world), and they were great for walking around town at night, giving my feet a break from my trail-runners.
Please don't skimp on the sunscreen, although you can bring it in just a small bottle. Being all day unprotected in the sun has very negative consequences down the road.
Paring down your possessions, imagining what you really need and what you really don't, is a challenge, but one that is worthwhile and really an enjoyable process to go through. How successfully you do it will be evident on your camino. I didn't throw anything away once I started walking, but next time my pack will be under 10 pounds.
Have fun figuring out what is right for you!
