Good thread guys....the info on the changes is great to have all in one spot. Anyone having more troubles? Or positive experiences with the '09 Jams?

Original Jam on 07/01/2009 15:40:21 MDT Print View

Just an update......I have the very original Jam and love the fit. Purchased the 2009 Jam and had to send it back because the haul loop tore out. Received a new 2009 Jam and quality was very good with no problem.

However, the fit of the 2009 is very different from the original and in my opinion not nearly as comfortable. I used it for a couple of hikes and it was just OK for comfort. Original was much more comfortable in my opinion.

My go to pack now is the ULA Ohm.....awesome pack.....awesome quality.....awesome comfort. Brian has created a real gem with this one.

GoLite Jam 2009 on 07/01/2009 20:17:21 MDT Print View

I have a 2008 Jam that I've used extensively, and my partner has a new 2009 Jam, so I've been able to compare them.

I have to say, despite the extra weight, I'm jealous of the new Jam. The mesh on the back panel and hipbelts adds a lot of stability and comfort, and the hip-belt pockets are great.

I don't think the fit is any different (for me), and if I were going to do it again, I'd just get the new one and not be such a gram-weenie.

Shaving Grams on 08/02/2009 19:32:35 MDT Print View

I've done some modifications to my 2009 Jam and I figured I'd share the details.

1) I cut the stitching on the sides of the hydration bladder sleeve (with a sharp knife and razor blade) and cut the fabric along the bottom since the seam is too dangerous to cut as it's right in a main seam. This was easy with the pack inside out. With the bladder and bladder clip removed, I shaved 28g (1.0oz) off the pack.

2) I cut about 3" off the sterum strap and about 5-6" off the shoulder and waist straps. This shaved off 25g (0.9oz). The waist belt straps are by far the largest and where most of the weight savings lie. I'm a thinner guy (5'11", 165lbs) so that should give you an idea of how much you can cut. I melted the ends of the straps which worked great although they do now slide through the buckle if I loosen the straps too far. I cut the shoulder straps almost too short (I should have filled the pack up with stuff before I decided how much to cut).

I did not cut the roll top strap, as it seems you need pretty much the whole strap when the pack is super-loaded....even though there seems to be a ton of extra when the pack is empty.

I also did not cut the side compression straps. These straps have a ton of slack if you don't want to be able to clip the two sides together. For now I'm keeping the extra straps here in case I ever need to bring my ridgerest. Clipping the side compression straps together to hold the ridgerest on the back of the pack is pretty much the only way to do this unless you rig up something on the bottom of the pack. I might just bring some thin cord and clip these straps...not sure yet. You could probably cut about 12" off each of the 4 straps which I bet would easily save an ounce.

Keep in mind the 2008 Jam2 did not have the ability to clip these side compression straps together, so of the 5oz gained for 2009 this extra strap length is likely the cause of 1-1.5oz and it is reversable if it's not valuable. I would say the hipbelt pockets are responsible for another 2-3oz....so in total these reversable updates are likely responsible for most of the weight gain.

3) The foam in the back panel weighs 34g (1.2oz). I like having this as it improves comfort and gives the pack a bit of shape (because I don't use a pad as an faux frame) but you could remove it.

FWIW, my 2009 Jam pack with the hydration bladder removed and some straps cut weighs 699g (24.6oz) and it would likely weigh around 21oz without the hipbelt pockets and back foam.

re: jam2 sewing issues UPDATE: jam vs ula circuit on 10/07/2009 17:07:01 MDT Print View

UPDATE:
I purchased a ULA circuit and used it as a comparison to the 2009 jam over a 4+ month period of travelling and backpacking. Mostly a ~10lb baseweight with up to ~15 lbs consumables for the long trips. I alternated the 2 packs for various trips with no rhyme or rhythm.

I concluded that the ULA carried loads over 15lbs much better than the jam, especially over 3+ consecutive days. But...apples to oranges because of the circuit's internal frame and load lifters. As for the jam's shoulder straps, they did not show any signs of pulling out after I bartacked the heck out of the 4 points of contact (due to previous sewing issues). No issues in quality on the ULA. The jam carried well on lighter overnights and weekends but seems to have excessive volume for its carrying capacity (barring the use of lighter and higher volume winter gear).

I have opted for what I feel is a better-made overall pack while supporting a fellow hiker and an US-made product. 3 birds w/ one stone despite it taking a few months to sort out. Out with the jam and in with the ULA.

"Out with the jam and in with the ULA."

Can't argue with that.

Ohm on 10/07/2009 17:16:32 MDT Print View

If you went with the ULA Ohm, you'd kill 4 birds because it's lighter than the Jam too. Have you considered the Ohm?

Re: Ohm on 10/09/2009 19:39:49 MDT Print View

I have actually been hemming and hawing over the Ohm vs the Conduit. I may opt for the lighter (and smaller) of the two just so that I am forced to minimize my ways. Suggestions are much appreciated -SMD, MLD, etc. But as there is snow on the ground and it is supposed to be 10F or less tonight here in MT, I can probably postpone this decision till spring. Volume-wise the Circuit should be fine for any shorter winter excursions.

Gorilla on 10/10/2009 00:35:54 MDT Print View

The GG Gorilla is an interesting looking pack. It might be too small (2800 cu in) if you are worried the Ohm is too small (3500 cu in) but perhaps you could use the Gorilla as a summer pack.

The Gorilla has a removable frame, hipbelt and sternum strap so it weighs 15 - 21 oz depending on how you set it up. It seems like a great pack for weekend getaways (in 15oz mode) and for longer summer trips (in 21oz mode) and then you could use the Circuit when you can't fit everything in 2800 cu in.

I haven't used my Conduit yet, but I think I would like the frame in the Ohm.
