2012 50L Golite Jam (out of the box)

Thanks for geeking out on gear lately Dave, cool seeing new pack options for folks. I was never crazy about the 2010 belt and the small hipbelt pockets, but the new wider version does look comfortable and generous. I am one of those long torso'd 32" waist folks, so probably SOL in picking one up if your experience has the belt maxed out.

It fits me just fine. It probably won't fit my wife, which is a bummer as (with almost identical torso lengths) we can usually wear the same packs.

Looks good. I'm interested to hear what you have to say about how it carries. I likely only have one more season left in my old model Jam.

Thanks for all the testing you've been doing, I've always appreciated the field usage criteria you try and stick to.

Are they doing away with the Pinnacles? Don't see the need for both since they looked nearly the same to start.

Edit: Nevermind, I saw in the other thread that Pinnacles are indeed discontinued.

After using it a time or two, I have to report that it carries, like a Jam. Supports the load just fine, hugs the body exceptionally well, just disappears during ski-bushwacking and other shenanigans. I'll repeat: a lot of people are going to really like the new belt design. The pockets are great; each will hold four snickers and a pair of powerstretch gloves without causing pressure points. And the zips are easy to use with one hand.

I can't confirm the rumor that this will be 100 bucks at retail, but that would be exciting.

That belt is huge. I'm 6'4" 32" waist and there's no way that would fit. Oh well.

35 liter jam? Are the hip belts the same on the 35? If so, I will replace my peak. The belt on the peak is horrendous.
However, I am a 30 inch waist. Do they have small sizes or am I screwed? I would remove those hip belt pockets anyways so does it really matter?
How did you get this…. did golite send it to you for review?

This pack was sent for a review.

As for belt sizing, I do not know. I would assume they'd adjust for sizing; a safe bet, but best confirm with GoLite. To inject some objective data here, the belt on this pack has a circumference of 32 inches (when the pack is layed flat and measured end of padding to end of padding.

Dave, can you post the weight and dimensions (including thickness & "firmness") of the Jam 50L's removable back pad?

If it makes a reasonably good torso pad for sleeping, I'd count that as dual use weight and deduct it from the overall weight of the pack. Many of the LW/UL packs being compared to the Jam have no back pad.

I emailed GoLite and they wouldn't tell me the pad's dimensions or weight, though they said it was about 1/8" thick. Anybody got more info? Would a thicker pad fit in the sleeve?

"I predict a lot of folks are going to like this belt a lot. But some folks, namely those much skinnier than me (32" jeans) with long torsos, are not going to be able to use this pack. As you can see, I have about 1.5" of slack left in the belt. I do tend to where by belt higher than many, however."

Confused here. From the picture it looks like you have over six inches of slack in the belt.

He means the amount of belt left to cinch, not the excess (ie if he were any skinnier, it wouldn't fit him).

I see now, thanks for explaining.

The new backpad is 1/8" thick, 2 oz exactly, and extremely stiff, dense foam. Earlier I said it was comparable to the 2011 pad, but upon holding them next to each other I retract that. The 2011 is 1/4" thick, and while very dense foam, is still foam. The 2012 pad is as close as foam can get to being a plastic framesheet and still be foam. Pinching it between my fingers leaves no dent whatsoever.

Very useful, thank you David. Do you think a softer, perhaps thicker pad would fit in the pad pocket?

If you cut the overall down a bit, then yes. The current pad fits very tightly.

how about fitting a pad in the bladder sleeve and leaving the thin oe one alone? I very much like the idea of something closer to a frame sheet vs a thick soft pad, that has to help in the carry department

I'd agree. Carry department is good.

A few notes on the new suspension components after a bit of use, including a recent trip where 3 days of food and 10 liters of water pushed the load pretty close to the packs limit.

The belt is excellent. The softer foam (as compared with '11) hugs the hips very well, and the extra surface contact results in a product which is very comfortable. While I still have a bit of slack left in the belt, even when pulled tight under a heavier load, the adjustment is awkward and less than ideal. I'll likely modify this.

I do think the new shoulder straps are less than ideal. It isn't the thickness of the foam, so much as the extent of the circular perforations (the '11 straps had this too, just must less). The resistance of the padding to loads near the upper end (25+ lbs) is not as good as it should be. I'd encourage Golite to go back to the previous generation.

How'd the new framesheet hold up to that much weight ? Any less torso collapse than the old foam ?

What the issue was with the new straps ? Did they curve into a tube and cause pressure – or something else ?

Are the hip belt pockets removeable ? The BPL review of the 2010 Peak makes it sound like they might be (if the pockets are the "removeable wings").

Also, any guesses on whether one of the SMD or GG hoop stays would improve the carry with 25-27 lb loads – and fit into the pad pocket ?

Thanks.

The straps are (for me) ideally shaped. No deformation or other nonsense. I'd just prefer a little more beef to spread the impact of the weight around.

The belt pockets are not removable (save with scissors).

The Jam carries 30 pounds well, if you pack it well. I'm not sure the newer, thinner yet denser framesheet performs differently than the 2011 one.

A major part of the article I'm working on will test torso collapse with both the stock configuration and other, MYOG solutions, which will include various sorts of stays. It wouldn't be hard to make such a device yourself. For instance, I've laminated an alu stay from the hardwear store between two layers of foam pad, which results in a very useable product at a total cost of perhaps 10 dollars. The dimensions can be tailored to suit.

You mind taking a photo of that laminated stay and sharing it with us? How much does it weigh? Thanks Dave.

They don't look like much, just two layers of various sorts of foam (glued with contact cement). The blue CCF from Walmart is cheap and sturdy. I've made several different ones for various packs and projects. Weights vary from 4 to 10 oz based on dimensions, thickness of the foam, and size of the stays.

I'll add this….I went to check out the new Jam's, and I'm not sure I'd want to carry anything over 20# with those shoulder straps.
