I finally did my first make-your-own project. I made a backpack out of a plastic bag you get at supermarkets here in Holland.
I designed it without a specific weight target, just wanted to learn how to sew and make it as light as possible. It came out at 3.5 oz and i'm very happy with that. When it was finished i did wonder if it was big enough (I guess it's about 1000 to 1200 cubic inch) but I tried all my SUL stuff inside and it all fit.
Here are some pics (note the measuring tape is in centimeters, each colour change is 10 cm ~ 3.9 inch):
Here's a pic of me carrying the backpack:
I designed my backpack to use my gulines as hipbelts, thus saving those fractions of an ounce that can get you into sub 5 or sub 4 gearlist. Here are some detail pics:
Here's a detail pic of how the guyline hipbelt connects to the backpack (note my sloppy sewing):
And the last pic of the shoulder straps connecting to the backpack:
It was a very fun project to do. I learned a lot. I used Ray Jardines book as a guide how to make the shoulderstraps and found those straps a bit small. I did redesign them a little so i can use my socks as padding like in my GG G4, but on a next project i will have to make them wider and longer.
I also didn't reinforces the area where the shoulderstraps are sewn onto the backpack and had to do that afterwards cause the material started to tear there. But it was a good leaning experience and next time i'll reinforce that area.
I'll use this backpack for SUL hikes with a three day, two night maximum and I hope I can stay under 14 lbs with food, water and all gear carried in the pack, cause I don't think it'll carry more due to the lack of reinforcing of the shoulderstraps.
But if it'll fale I can always make a new one.
Material costs: less than $ 10,-
Time to make: about two aftenoons.
Let me know what you think,
Edit: oh, I made the pics with my telephone so the quality isn't very good, but I think it'll do. I also reduced the pics in size reducing download time and scroll effort.
