To me this article seems as out dated it’s circa 1988.
I do not believe anyone would wear any of the packs mentioned to fastpack 100 miles in 38 hours.
It seems that everyone just needs some type of intervention between light weight backpacking and fastpacking. There have been 100's of forums started as to "what do you define as fastpacking". The question is usually answered with even a broader spectrum than a question such as what do you consider light.
I have yet to read an article on fastpacking that sheds any light on the subject as its definitive for what the term really means. I can understand this, because if someone wanted to "fastpack" then the terms would have to meet "there" needs and abilities. And in accompanying the 10 mile a day hikers that want to go for a 15 mile a day jaunt or "fastpack", the term becomes so loose, it makes understanding it way too complicated.
For the majority of the topic about the term "fastpacking", one must only look at the word itself to come across the simplest definition; "FAST"!!! Other words that come to mind are simple, less complicated and multipurpose.
Fastpacking does not have to just mean the rate of distance per day or the speed one travels doesn't have to matter. A greater concern though is freedom of movement. Such as getting over a boulder fast or being able to run without haveing any restrictions of movement or having a pack bouncing up and down.
All of these restrictions hinder the movement in such a way to slow you down, (hence the opposite of fast).
A am sorry, but none of the packs above would even remotely come close to qualifying as a “fast” “pack”.
In 2007 I started a “fastpack” trip on the JMT with 14 pounds, including water, with enough food for 6 days. The pack was a Nathan 859 with about 1100 CI of volume.
Since then I have overhauled everything and learned a great volume of hands on information as to the term “fast”.
This years JMT Supported Record Aattempt was with a Salomon XT Wings 5 Pro pack with the additional custom front pocket. Although the set up was not perfect, it has led me to what I use now for my fastpack trips.
I now use an Osprey talon 11 or the Osprey Daylight pack with the Salomon custom front pocket attached to it, via sewing machine.
So what does all this mean? I believe the term “fast is looked at too loosely. We need to ask ourselves some questions if we want to consider a fastpacking trip.
What is the smallest, simplest easiest to use pack that we you can put the warmest yet smallest volume bag or quilt in plus food and water. The rest of the necessities you really need do not add up to more than a few hundred cubic inches. What is the fastest way you can both get to your water and refill it? What is the minimal gear necessary to get the distance completed? All of this may not be the lightest, but it does need to be the easiest and simplest to use.
It would just be nice to have the subject of fastpacking enlighten me in some way and make since to me.
It is now 2010, some 22 years after its first mentioning. In 1988, fastpacking was a true and pure meaning of what it stood for. I don’t see it coming back any time soon.
I’m sorry but “FAST” is not a 44 liter pack!
