TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

I made a Jam lid

I have made a Jam Lid

I have a Golite Jam. The pack has proven very comfortable, and with a 50 litre capacity, enough for me for extended hiking. I took it on an eight day hike recently, it has been with me on several two or three day hikes.

The major down side of the pack is that it does not have a top. So when filly packed you get a little hole in the top. The pack s designed so that you roll the top down to keep it water tight. Fine for three days, but not for eight days of hiking.

So, after experimenting with a small plastic disc over the hole, I decided to make a lid. Now I cannot sew all that well, nor can any of my family, that meant that any design had to be easy to make.

The lid had to comfortably cover the hole when full, yet not get in the way when only taking the pack on an overnighter.

The materials were 19mm webbing, covered dymena 2mm cord and 82.3 gms/sqm Cuben Hybrid. This material is made from 48.4 gms/sqm Cuben Fiber, with a protective layer of 50 Denier Polyester on the outside. And finally two useful guy rope tensionsers.

The photos below show how it is supposed to work when both full for a five day and beyond trip, compared to an overnighter.

Thanks to nuts for his suggestions and his nifty hot knife.

What a fantastic idea. Plus your sewing and attachment looks pretty good to me :-)

Neat! One of the resons I hesitate to get a Jam is the lack of lid. I have seen this
http://www.backpacking-lite.co.uk/diy/make-a-jam-pack-lid.html
which looks great but it is way beyond my capabilities and confidence. Yours looks much more doable!

My sentiments exactly when I read the same article. Simpler the better for my skills.

Much better than you're old Chinamans plastic hat Penguin!

What's the horizontal black webbing just above the pack's carry loop in aid of?

It stops the loops creeping around the compression straps. When I made the mock up the loops on the compression straps wandered all over the place. The strap seems to help.

I miss my chinaman's hat.

Hi Penguin

Look forward to seeing it in the flesh. So master gram counter what is now the total weight?

Actually the cap seemed to work well.

Cheers

Well..I actually suggested the S2S Kitchen Sink but I don't think he could see a place for the dish rack :D

Do you think 19mm webbing is strong enough to achieve that? :P

At least when in place. Everytime the top of the pack touched a stick it got knocked out of place. Taking along someone as a "cap putter back into placer" helped a lot though. :wink:

Nah it looks good, should really help the Jam fit niceley with the cuben chaps, yellow waterproof undies and newspaper jacket. :D

Um? Did not realize that you had picked up additional duties to those of been water bottle fetcher.

Yes the complete outfit. At least we can thank the wind gods for removing that cap! I am dreading the next step which might be a complete outfit made out of cling wrap.

At least the bright yellow shoes are no longer so bright.

Have noticed with some items pushing light weight that a few simple and not that excessively heavy things are missed yet there a rather an abundance if straps, etc on some packs.

Still good to see in the real world lighter gear. Let's hope the next trips proves the modification to be a winner.

Hey, why does all hiking gear have to be drab :)

Maybe we could vacuum pack ourselves before we go as a waterproof, windproof, light weight protection?

I will settle for nothing less than a solar powered force field. It's see-through, keeps off the bities as well as the weather, and pushes the scrub aside when you're off track.
