Hi guys,
Apologize if this has been asked before, but despite searching I've not come across the answer elsewhere.
I've got plenty of time for testing out the existing pack over the summer, but I know there's plenty of more experienced folk around here too!
Hey Dave - I think I'd disagree in this case. A large bag would have the majority of contents at the bottom and further away from the body whereas a smaller bag would hold the items closer to the body and higher up. This would change the COG/weight distribution for sure. Unless the large bag had internal compression straps that held all gear close to the spine vertically in the pack a smaller bag, tighter to the body will be more stable, balanced and secure. Is that imperative on the Camino? Probably not, more of a technical climbing consideration I imagine.Hi, Rhun...
Bottom line: No.Center of gravity and weight distribution are not affected by low volume loads. The method of packing and arranging the contents of the pack are what affect those issues. There is no reason at all, other than perhaps saving significant weight, to purchase a new pack simply to accommodate a small volume load.

My tuppence worth is,,,,,
If the pack is light, you are happy to wear it and it is comfortable, why change it?
Remembering to put your heaviest items highest in your pack, should, by all accounts prevent any back or other problems.
Stick with what you know works for you might be appropriate in this case.
Buen (correct-pack wearing) Camino
I thought the heavier things should go in the middle of the pack, not the top. ?
And apparently a huuuuuge bottle of wine!but then again I walk with sandals
That is a good and logical supposition, JoeIn practice, though, that isn't the case with just some basic guidelines and experience.
For low volume loads, the center of gravity isn't affected by the height of the load due to the lighter weight. And packing will allow the load to be held in compact fashion to keep the load from shifting. It must also be kept in mind that a half-filled bag still allows for heavier items to be placed mid-bag.
Sorry to still disagree Dave but over 800kms, carrying 5-10% of your body weight in a back pack that has a lower COG and a COM that is further away from the body will have an effect. It may be possible to use compression straps to bring all the internal mass closer to the body and higher however my belief is that it isn't practical and most people. I believe that a (mostly) full 35L pack is going to be allow better weight distribution (heavy items up close to shoulder blades), better posture and less repetitive strain than a half-full 70L. Right tool for the right job
That's correct. It helps things from becoming too top-heavy.You understand the importance if you ever bend down a bit with a full backpack on .
One huge advantage of a smaller pack is that you can often carry them on board an aeroplane as cabin luggage . Having done this once and reaped the benefits of a smooth, fast and anxiety free disembarkation it would be an unusual circumstance that would make me want to check my pack into the hold again .
I guess I would want to know how much the 70L pack weighed. In my experience, packs of that size are often built with a substantial suspension system to allow carrying heavier loads. Those features also often come with a substantial weight penalty, If you can save a couple of lbs by using a smaller and even lighter pack, more suited to your expected load, I would be inclined to go that route since you will be covering so many miles over several weeks.

hahaha!!! well, I did not know it would look like that when I took the photo myself, I take selfies with the normal lense in the mobile, I never know what will come out; it is great, you some times find these surprises (Villafranca de los Barros, VdlP)And apparently a huuuuuge bottle of wine!
At the end of our Camino, my son packed the top of my pack with a lot of cheese and chocolate. I picked up my pack and swung it on, and said "This is too heavy." He said "Mom, the train station is less than a km away. " Right. So-- I walked. And my knees hurt for 6 weeks afterwards.
Always listen to DAVE. He always knows what is best for his Camino children!Hi, Rhun...

There is no reason at all, other than perhaps saving significant weight, to purchase a new pack simply to accommodate a small volume load.
I appreciate your point of view, Joe, but I carried my 65 liter pack with it being less than one third full twice (at around 9.5 pounds) on Camino; once from SJPdP to Burgos, and then again from SJPdP to Santiago -- and all was good. This is the same one that I used on a thru hike of the Colorado Trail with full loads for 7 - 10 days between re-supply points. I also do the same with it on short backpacking trips for a weekend. The same experience holds true with a lot of backpackers who will use their large capacity packs for short overnight trips as well as weeks long trips under full loads because they do not want or need more than one backpack.
The genuine issues you are concerned with, which are a good idea to avoid, simply do not occur just because there is a small load in a large pack. I've not seen this as a causal relationship in all of my decades of experience. Additionally, in packs with proper shoulder harnesses and hipbelt systems, there is less of a concern about load placement than in the old days of external framed 'Camp Trails' style packs.
VERY INTERESTING...I was just going to write that it did matter having a half empty backpack because of weight distribution. Would be really interested in your thoughts on the situation that I encountered. If you have time to respond! Last year, well 2017, I used a 55 liter Osprey Kestrel pack and by the time I got it to the weight I wanted (on the second week of the Frances) I felt everything was riding too low and being uncomfortable. I began to devise ways to get the weight up, as in inflating some plastic ziplocks and putting them at the bottom. I loved the way that felt. For about an hour. Then they would slowly deflate and the stuff would sink. I began then wondering if I could find inflatable beach balls in some village that wouldn´t deflate. Surprise. Didn´t find any. But returned determined to buy a smaller pack. What do you think was going on here? By that time I had become pretty versed in using all the straps to adjust the weight, but I sure didn´t like the weight hanging low in the pack. Need to figure this out since I am setting out on the Primitivo beginning of May. Appreciate your good advice.That is a good and logical supposition, JoeIn practice, though, that isn't the case with just some basic guidelines and experience.

And packing will allow the load to be held in compact fashion to keep the load from shifting. It must also be kept in mind that a half-filled bag still allows for heavier items to be placed mid-bag.
When I would shuttle loads between staged camps on mountaineering expeditions, it often involved hauling huge weights from the lower to an upper camp, then bringing a smaller load down. Believe me, with having to use ice axes and crampons the last thing we would allow to happen is a pack that could throw us off balance.
In heavy loads, the placement of the load so that heavier items sit from near the center of the pack affect not only center of gravity, but also comfort.
Also, you mentioned compression straps. That is also an option to help manage a small load. Many larger packs incorporate external compression straps for just such a purpose. If I use them, it is usually to form a smaller profile to an underfilled pack bag.
Some empty capped water bottles might have done the trick.I began to devise ways to get the weight up, as in inflating some plastic ziplocks and putting them at the bottom. I loved the way that felt. For about an hour. Then they would slowly deflate and the stuff would sink.
Hi, Sally....Good grief DaveBugg, have you been on "clothing optional caminos"? Would you please share what you would pack from SJPDP to Santiago to have a backpack weigh in at 9.5 pounds. I am obviously making some poor choices. I didn't even carry a sleeping bag!

Does having a half-filled pack affect weight distribution ... ?
Experience leads to knowledge, leads to confidence, leads to needing less. Keep this in mind when looking at my packing list

Rhun, there is a lot of good info in the replies. One question you did not answer was what is the empty weight of your 70L pack? There is no need to use a pack much over 2 lbs. If your pack is 7 lbs for example, the burden of carrying that extra 5 lbs is greater than anything you might do in terms of load distribution.
I have about the same collection of packs as davebugg. I've been experimenting with this exact problem. My Zpacks was about half full with 15 lbs, and I could the weight sitting on my tailbone. I cinched up the pack compression cords until the load was a vertical column to the top of my pack. It fitted nicely against my back after that adjustment, and was more comfortable hiking.

Thanks. Will try this idea! My carrying weight will certainly be below the capacity of my bag! Am determined this time to be more economical with it all. I nearly killed myself the first time crossing the Pyrenees with way too much weight. Started giving stuff away immediatelySome packs are better than others at keeping the pack bag from sinking below the top of the hipbelt. A pack suspension that allows the bag to droop in this manner will cause the type of issue that you describe, and exactly what Joe was talking about.
Solving that issue in a 'sloppy bag' is usually a simple modification if the pack does not have external compression straps. Apply a strap to each side of the bag on any convenient attachment external to the hipbelt or to the bottom fastener of the bag's closure system. Loop the top of the extra strap (or it could be some sort of cordage) up to the top buckle of the closure system or to any tie off's or external loops on the upper bag. Apply tension so that the droopy bottom lifts above the top of the hipbelt.
There have been a few packs which I have done this to and it works well. It saves the cost of a new pack.
A lot of large backpacks have stiff enough suspension systems which do not require any mods. The same with large packs which have external compression straps
Dave:Hi, Sally....
I doubt if it is an issue of poor choices at allIn previous threads I have mentioned that gear and clothing choices are mostly affected by frequency of use and purpose. Sort of an algorithm of decision making which includes a Dollar/Euro/Currency per mile/Km ratio. If one is only going to walk. For example, if one is only looking to walk Camino, which for the Frances is about 800 Km/500 miles, would one spend the same amount of money purchasing ultralight gear as someone like myself who backpacks many hundreds of miles throughout every year?
Realistically, the trade-off of expense vs weight is a real concern to most heading out on Camino, who will decide that budgets favor saving money.
For gear choices, it is a matter of knowledge. I am very familiar with most gear offerings by a large number of manufacturers. Some of that is because i am hired to test backpacking gear and clothing. Some of that is because I have been backpacking and mountaineering for decades and have a lot of practical experience.
A person who is deciding to walk a Camino, but who has never been backpacking before is faced with not only trying to figure out what s/he needs clothing and equipment wise, but has no real knowledge of the breadth and depth of clothing and gear options. They will be struggling to make decisions on a backpack, for example, without having ever worn a backpack for a multiday walk. They do not know what will work for themselves. Most of what will inform their decisions are what other Forum members say worked well for them, not practical and hand's on experience with a broad range of manufacturers and models.
So if those of us who have a broad experiential range of knowledge from the outdoors and backpacking voice an opinion as to an ultra lightweight choice of a backpack, which is not a well known brand, it is a small voice among many.
The other factor is that if a large number of folks have a positive experience with a backpack, but that specific backpack is heavier than a less well known model which performs just as well but which they have not tried, then a recommendation will be limited in scope. That does not mean that the backpack recommended is bad, it only means that the knowledge that an equivalent lighter choice is available is missing. The same analogy applies to clothing, sleeping gear, etc.
As a practical application of the above, someone like myself will have the same type of gear as a less experienced walker, but because of my experience my gear will weigh less by 50%, or more.
In summary, someone having a backpack load which weighs more than my pack is less about 'bad' choices, but about knowledge and budget. And keep in mind that my pack load will weigh more if I decide that I want to add other items based on need or want.
As an example, this last September on my second Camino, I had decided to do a full step-by-step video recording of my walk over the Napoleon Route fro SJPdP to Roncesvalles. To do that 10+ hours of continuous recording added nearly 5 pounds to my normal 9.5 pounds. After Roncesvalles, though, I mailed home my video gear so that I went back to my normal load.
But choices of gear, what one decides is a necessity, packing for fear, etc, all affect how heavy one's pack will be. Because of my experience, I am confident that I can face most walking related issue regarding weather, injury, comfort level, etc with much less than those with less experience.
Experience leads to knowledge, leads to confidence, leads to needing less. Keep this in mind when looking at my packing listAlso, I dropped the Xero sandals from this list and replaced them with a homemade 1.5 ounce pair of shower shoes. Adding a liter of water to the pack adds about 2 pounds; so minus 9.5 ounces from the list, and then add 2 pounds.

Dave:
Many thanks for your thoughtful and comprehensive reply...you know no other way. I have shaved off close to five pounds with better choices. Lighter weight clothes. As your tag says, "You do have our backs...always!"
