Walking the camino does not require a lot of stuff, even in the winter. Our next pilgrimage will be during the late spring and summer months, and will require even fewer things, or at least lighter versions of the same things (shirts, jackets, pants, sleeping bags etc.). As the overall carry weight weight deceases it becomes harder to justify a pack weight that represents 50 percent of your base weight. So, armed with this understanding, I started searching out other options. As I looked into ultralight equipment I happened upon a company called Zpacks (based in Florida). I did some research, and placed an order for a 45L version of their Arc Blast pack.
This pack is constructed with ultra light Cuben fiber (waterproof and breathable) overlaid with polyester (for additional durability). The pack only weighs one pound. I also purchased 2 belt pouches, 2 side pouches and a chest pouch. The total weight comes to a very lean 21.3 ounces (1.33 pounds). This pack also comes with a carbon fiber external frame with a mesh back panel, that will be most welcomed in hot weather. There is a 3 week delivery wait. All packs are custom built, and zpacks seems willing to modify your specific pack anyway you want it. If this works the way I expect it to, I will place an order for Robin as well. This company sells a variety of other ultralight equipment as well (see link above). Robin and I have both used Altus ponchos for our winter walks. They were great in that environment. Now, as we face walking in much warmer weather the Altus, I fear, will be too hot. Zpacks to the rescue. The poncho shown below weighs 5.1 onces (the Altus weighs 16 ounces).
I am still making adjustments to my packing list, but with the equipment above I feel I can get my base weight down to 10 pounds (a much lighter wallet will help drive that weight down as well). I'll post more later once I am able to get out, and walk with this gear in the Pacific Northwest weather. Looks promising!
