MYOG in Israel backpack !!!!

Are pretty rad. Certainly professional looking. Do you have specs (weight, volume, materials, etc)? Someone was bound to ask :)

I think they look very professional and very heavy. What do they weigh and what materials did you use?

These backpacks are built tough, and for extreme use. But still weigh relatively little. They are designed to intensive daily use.
Fabric: 500D and 1000D High quality nylon, coated in PU
Plastics: GT NEXUS buckles military standards.
All zippers: YKK 10
Aluminium: 6061 – T6
Smaller backpack is 35 liters.
Larger backpack is 70 liters. And has a back system that can cope with very heavy weights if necessary.
I did not check what the exact weight of my backpacks, but the 35 liters weighs about 1300 grams, and 70 liters about 2500.
Definitely not ultra light weight. My goal was to create a very strong rucksacks, weighing as little as possible.
I believe that what interests the majority of the members here is the 35 liter backpack.
It is designed for fast treking with low weight, and his back system is built so that it barely restricts the movement of the body.

Maybe the IDI would be interested in combat versions, considering your bombproof construction.

MOLLE type webbing for attatchments, Cordura reinforcements, detatchable lid compartment converting to a butt pack, etc. all would linterest them. Don't forget access for hydration hoses and radio antennas.

Thank you Eric,
I believe that in the future I'll make military variants like you're talking about.
Not long ago, I designed a back system integrated into a military medics vest for an Israeli tactical brand, it was a very interesting job, I enjoyed it a lot.
Some of the inspiration for building these backpacks came from military backpacks, combined with the characteristics needed for civilian backpackers.
Meanwhile I'm trying to reduce as much as possible these backpacks weight without hurting their strength. It is characteristic that really needed to Israeli backpackers (the strength), this makes the task of reducing weight very complicated.
