Best zippers for the peso are in the L.A.Cafe They work they way you dream about. But you know that.
Thank you. I am not so opposed to explaining countries. It is a huge problem to use words that change the over all theme of the site.
Glad you have finally tracked down a source for the elusive number 10 hasp slider zipper component.
Will you have two designs as you carry two packs? At least I think you have two. (One day pack for things you never check on a flight, and a larger pack that you might.)
For what it's worth I'm using a day pack that has a combination of rip-stop and military grade ballistic nylon. Light weight (1kg) yet very durable and water repellent. I'm happy with it for my purposes.
After looking up the Spectra and Cordura material details, they seem to be superior in the durability category.
I just wonder about the relative weight. As a confessed lightweight fanatic, I'm always curious as to the weight differential in various materials and products.
I've seen ergonomic studies that show a person should carry a maximum of 15 percent of their body weight if using a backpack. If more, they say it should be on wheels. Your previous post showed you had a 30 kilo lifestyle, and I wonder how much of that is wheeled and how much is on your back (if any).
According to this a 90kg (198lbs) person carrying the max of 15 percent would be 13.5kg (30lbs). I'm in decent shape yet I feel even 10 percent is a lot on my back when walking long distances (which I rather enjoy at times).
It's none of my business, but if I were designing packs I'd take this into consideration when looking at capacities, materials, the likely items it might contain, all the associated weights of such, as well as the intended users.
Slightly off topic, sorry...
Zippers; that's one area I wish I had better security on my pack. I can lock the main compartments, but I think it really only keeps out the amateur thieves.
Wish you well on your backpack project. A custom pack is truly the only way to get exactly what you want/need.
Confusing to explain, however I am making a carry on size, that will convert to double that size. I can carry two bag of equal size, one on front and one on back, and the sizes could double.
Both bags will have optional, I will use wheels. A backpack is not needed except for steps and mud, trains and bad terrain.
Waterproof and super lightweight, we are trying to keep bag under one kilo, or less.
Balaning of front and back makes carrying bags easier, but to me on top of the head make more sense.
One zipper to lock per bag, but opens easy to expose all, layers and such to stop knives, and it is a system.
I plan on making extensive videos to explain.
Forgot, we have a list of about 300 items carried, and engineered into the pack how to carry all of them.
A person needs to collect all the items they want to take before they buy a bag. Weight it, size it, then buy the bag.
