Another adherent of the MS Tour pack, in a very fashionable, tasteful black (you can only imagine how important that is to me), also with the add on straps. It carries very comfortably and is great for the shorter hikes. I also have a very old (about twenty years) North Face lumbar pack - a so called "climbing model" (it features a few gear loops) which I really like when I am on my bike.

Both of these pretty much guarantee that I will have a basic essential load with me all the time. I didn't realize that they were shunned by fashionistas - that's their loss.
