Here is my first project ever.
The pack might have some small defects but it has worked for about ten of ski mountaineering and another five at resorts. I've done some bad falls also and still it holds together quite well.
It is made of X-pac seconds (165 g/m2) bought from extremtextil.
The hip belt is from one piece and goes on the inside of the pack and when it is tightened the fabric won get stressed. The hip belt on the inside of the fabrick is about 1 cm shorter then the piece of fabric.
I got some hooks on the sides so that i can put my jacket on the side or some other gear. I don't think the hooks would hold my skis very good.
To get the pack a little nicer to carry I have a piece of cheap sleeping mat at the back and as shoulder straps.
The side pockets hods 0.5 liter bottles quite well.
The weight is about 250g (9oz)
In the pictures the the backpack is filled with stuff I need for a day at the mountain. I could have filled it up with a sleeping bag which would make it look nicer.
4 persons bivy bag
I've bought some more x-pac and plan to do a little nicer one. But I think this one will be used when don't need any fancy gear like axes rope etc.
