20L backpack pattern ? on 02/11/2010 18:44:04 MST Print View

Do you know a simple 18-22L backpack pattern? I would use it for mountain bike touring (water bladder + clothes) and as a winter xc skiing daypack.

have you looked at the MYOG: 5 yards to SUL article series? The backpack pattern (part 4 i think) is pretty easy. The pack is a little bigger then you are looking for at ~27L, but since you are making it i think that it would be an easy mod to just make it a little smaller. Adding a hip belt, a bladder sleeve and using tougher material, and i think it would work just fine for biking with.

20L backpack pattern ? Free plans on 02/16/2010 14:28:49 MST Print View


I have plans for a 32L pack that could be narrowed 2 inches to approximately 20L. You're welcome to use them.

You can have the pattern printed full scale for about $7.50 at a print shop.

While it may not be exactly what the OP is looking for, it is exactly what I'm looking for, so thanks.

Try posting your question on the Bikepacking Forums:

A number of the members make their own gear and a couple have made backpacks. The most popular commercial model used by that community seems to be the Osprey Talon 22. It has an excellent harness system which you might want to copy.

Get a cheap kids backpack at the thrift store and a drybag style stuff sack from your local outdoors store. Cut the pack body off, leaving just a backpanel and shoulder straps. Sew your drybag onto that. Saves hours of sewing. Or check out CiloGear's 20L worksack. I use it for mountain biking and climbing.

Have seen the CiloGear 20L. Look pretty nice. I prefer a padded backpanel for mountain biking. I though about the dry bag + kid backpack.

I took several ideas and am sewing one right now. I will post picture when done. It will not be as light as some BUT it will be mine and adapted for my use. Much work than i thought. In fact, the padded backpanel tooked more time than i was thinking. Everything else is not too tough.
