This is a follow-up to my previous posts on this subject.
In one of my posts I expressed the opinion that I thought that, for me, the ideal pack might be the Osprey Kestrel 48 in (Small/Medium) instead of the same pack in Medium / Large. Afer all, it is what I walked the Camino Fancis in this past April and May. Well, I did more research on the subject including going to my local REI store and driving the person in the backpack department crazy for a couple of hours. Hey, I am retired, I can do this...
First, about me: I am a 60 year-old male with a barrel shaped torso (big chest). I WAS six-feet tall (185 cm) last January. But recently I had a full physical exam, at which the nurse proclaimed that I was five-foot-ten and 3/4 inches (180 cm). So, I am shrinking...darn and drat! However, most of my height is in my legs. I suspect that walking the Camino may have had an affect on me in that I specifically recall having to shorten my rucksack back panel so the hip belt rode properly once I got to Burgos from St. Jean.
Back to the REI store: The first thing we did was use the yellow plastic Osprey back measuring frame to accurately measure my torso height / length. I had to ask several times for a precise measurement as I could not see was was going on behind me and I wanted specific numeral information. The sales person informed me that the precise measurement was 18 3/4 inches.
Previously, I had contacted Osprey who informed me that the cutoff point for their Small / Medium and Medium / Large length rucksacks was a vertical torso measurement of 19 inches (48 centimeters).
NOW I knew what the problem was! My body was at or slightly above the 19 inch cutoff point for the Small / Medium frame BEFORE the Camino this past spring, and slightly BELOW the cutoff point six months later - read shrinkage above. So, it was possible that EITHER bag MIGHT work. It was also possible that other brands might fit better. So, the game was afoot...
Knowing how my Kestrel 48 (M/L) fit, I tried the Kestrel 48 (S/M) as I knew it was the same pack albeit two inches shorter vertically and held a true 46 liters as opposed to 48 liters. We placed 25 pounds of sandbags in the bag to approximate my expected load.
The finding was that to get a good fit, we had to lengthen the small - medium back panel to it's maximum possible length. In other words, all the embroidered Osprey bird sihouettes used for measuring were showing. On peering down the pack panel, this meant that not 100 percent of the monster Velcro fasteners were grabbing. There was an overlap. Perhaps only 80 percent of the Velcro was grabbing. In my view this was not good for safety. It would not do to have the shoulder straps slip while on a steep climb with a precipitous drop off...
So, back to the Kestrel 48 in M/L. This is the bag I bought last year and walked the C/F in . Only when we adjusted it slightly BEYOND the shorest increment on the adjustment panel (the little birds embroidered were ALL hidden) did the hip belt ride properly. However, that left me with a simple choice regarding the two Osprey Kestrel bags. Did I want the slightly smaller and lighter (3 ounces) size adjusted past what I thought wise, or stick with the bag I had and simply adjust it as short as possible.
I should also add that, while I was there I thought I would drive the sales person completely insane and try several other brands on. I tried the Osprey Atmos, Stratos, and Talon bags, as well as a few Gregory and Deuter bags. However, in my considered opinion - and this is HIGHLY subjective - nothing felt as comfortable to me as the Osprey Kestrel 48 in Medium - Long. It might have been familiarity. But, the Kesrel in 48 M/L with 25 pounds of weight in it, and properly adjusted using the sales clerk and mirros to make it "just right" left me with a rucksack that fit like a broken-in shoe. So, I left the dance with the girl I brought...
I cannot emphasize enough that this is MY finding. It works for me. It might not work for you. But what it DOES do is highlight the critical need to be properly measured and fitted by someone who knows what they are doing. The time to make a wrong choice is in the store BEFORE you are on a Camino.
I should add that there are a lot of videos on You Tube about "How to size a backpack..." or "How to measure for a backpack." Excersize due diligence before you even go to look at backpacks. All the pretty colors sand choices available may lull you into buying the wrong bag. One wonders if that is why Deuter puts small yellow, silk flowers on all their women's rucksacks...
Once you identify the absolute best bag for you, only then should you consider price and how you might obtain the bag at a lower cost - like on the internet - if that is a critical thing for you. Don't forget to factor in the cost of shipping. Personally, I felt compelled to spend my money locally and pay the extra money to REI. Besides, they give me money back every year based on my previous year's purchases.
Sorry for the length of this, but you know how I am. I like to provide the full story.
I hope this helps someone.
