Has anyone had a chance to try the new Golite Jam 70 out?
Curious as to what type of weights it will handle.

The suspension is exactly the same on both bags, so they should top out at the same max weight.
Looking side-by-side at them in store, the difference between the 50 and 70 are solely volume. The 70 is deeper (from frame-sheet outward), and taller. It could possibly be wider from side to side, but its hard to tell with so little structure to the pack.
I tried them both with bean bags and they both got uncomfortable fast at >40lb. The 70 had a good bit of room to shift the weight around, the 50 was stuffed full. I'd say 35-ish is the max load for comfort.
In the end, I bought the 70, to take it home and test-fit it with my gear. I'm still on the fence whether its overkill or not. I can pretty easily fit all my gear in and the pack is below shoulder height, but it looks like a beach ball on my back. I can get it to stack much taller by limiting volume with the straps, but its a tetris game to get it all in and balanced.Mar 30, 2012 at 9:57 am #1861525
thanks for the info
I am not able to try them out as i am in Alberta so have to order on line. Construction wise would it take a 60 lb load or would it come apart?Mar 30, 2012 at 10:14 am #1861535
Won't come apart but 60 lbs is way, WAY too much for a frameless pack.
You need to reduce your load by about 1/2 if you want this pack.Mar 30, 2012 at 12:02 pm #1861592
If you are carrying 60#, why are you even looking at a pack without a frame? That makes absolutely no sense at all.
I have a Pinnacle. I've been carrying 25-30# for training hikes. Would I recommend more than 30#? No.Mar 30, 2012 at 1:13 pm #1861614

If you are in a position where 60 lbs is the required gear load, I share the above opinions: frameless packs are not for you. I would even go so far as to suggest that you shy away from any UL style pack, framed or not. Get something that has plastic or aluminum framestays and is made of heavier denier fabric. It will last longer.
Let's be real, if you are carrying 60lbs or even 50, you're never going to notice the weight difference of a 5lb pack vs a 2lb one, but your back and shoulders will thank you all day long with a rigid frame and some structure to the sack itself.
Out of curiosity, what on earth does that 60lb packing list look like?Apr 2, 2012 at 8:32 am #1862497
My pack weight is not anywhere near 60 lbs…more like 25-35 lbs for a weeks worth depending on the trip however…
Sometimes my pack is carrying more when I come out than when I went in ;) so I was curious if the pack could handle the weight. My wife has a pinnacle and it has packed some heavy loads without fail so I thought I would look at the new Jam for myself.
Normally I have a 6-7 lb pack that I am using for these trips but hate carrying a bag that is that heavy empty so I figured I would give a 2 lb pack a try.

Posting here since it's essentially the same pack.
Wondering what people's thoughts would be on the 2012 Jam 50 supporting a max weight of 27-28lbs for a trip to the Sierras in July?
I'm still refining my final list so it may lighten up a bit, but trying to have the foresight to get a different pack if I need to. Base weight will be around 12-12.5lbs (including a Bearikade Weekender, required), plus 8 days of food @ 1.5 PPD for another 12lbs. If I have a full 2L of water, that's where I'm up in the range of 28. I've done a 29lb test load using a sleeping bag and a 3-season tent to fill it, and then throwing in books to fill in the rest of the weight. I packed the books laying flat so that they (hopefully) wouldn't add any structural rigidity to the pack. I am unable to test it with the bear can because I'll be renting it and won't have it until right before the trip, but I know it is compatible (albeit just barely).
The pack fits me well, and seemed to carry surprisingly well, but carrying it around the neighborhood is much different than up and down mountains all day. I have not hiked in it to test because it's still new w/ the tags (and thus returnable)
To create my virtual frame, I use my 3/4 length Prolite. I pack it in a cylinder and face the valve up at the top. Pack everything in the middle, tighten the compression straps, then I puff a little bit of air into the pad. This configuration may change once I have a bear can in there; I'm not sure the pad will fit around it.
– the Jam only cost me about $100 new (sale). If I don't use it, I'll probably shell out for a ULA Circuit or Catalyst, which no one ever sells used so that won't be cheap.
– I'm not a thru-hiker. 8 days of food is the most I'll ever carry; usually less
– Once I arrive and see water conditions, I may be able to only carry 1L of water at a time, but since I don't know for sure, I'm planning on 2L
– I'm 29 and fit, have moderately strong core and shoulders from entry-level rock climbing, but prefer situating the pack so most of the weight is on the plush new hipbelt design
Thoughts from those experienced–will I be miserable the first few days, or think it'll handle it?Jun 13, 2013 at 5:49 pm #1996422

Why books, plural? Why not an e-reader, cell phone, ipad mini…etc where you can carry dozens of books for the weight of one, not to mention less space? I use a Nook, and while it weighs just slightly more than two standard paperbacks it's only 14 oz…and the Nook is one of the heavier e-readers. The batteries typically last for days.
Just a thought.Jun 13, 2013 at 11:51 pm #1996510

I carried a Bearikade Weekender inside a Miniposa sack two years running on the JMT.
The sack is 42 lt made of silnylon and mesh and I took the stays out to make the sack weigh only 15 ozs. The can is a snug fit within, and so the can itself provides a rigid frame. To prevent the bottom edge digging into my back, I sat it on my sleeping bag. This way I was able to carry 34 lbs which included 10 days food. Oddly enough it made for a very comfortable carry. Not bad for a 25 lbs rated sack.
The Bearikade is a looser fit in a Jam 50 lt but you can pad it out with clothing etc.
You don't always have to use a heavier framed sack for occasional heavy loads.Jun 13, 2013 at 11:57 pm #1996511
I think you misunderstood me. I was using books, and a heavy tent and sleeping bag, just as weights to load the pack up to test it. I have one paperback book I'm going to have with me on the trail that I intentionally haven't read because it's a relatively small and light one haha. Just can't get behind reading a book on a screen. My deficiencyJun 14, 2013 at 12:06 am #1996512
Thanks, John, that's good to hear. I was doing some testing with a metal wastebasket that's close to the dimensions of a Weekender, but an inch wider in diameter. It did help create a rigid frame, but it also pushes the pack away from my back. I think using clothes and stuff to fill in around it like you say will work out the form fine. My concern is more with the pack handling the overall weight. A lot of folks STRONGLY urge 20-25 lbs max in the JamJun 14, 2013 at 3:19 pm #1996724
I started a 5-day Grand Canyon trip last month with approx. 35 Lbs in my Jam 50. Most of that was water/food weight. It held up OK on the first day — although my shoulders suffered until I got the load adjusters dialed in. By the 2nd day, minus 3 liters of water (6.6 lbs) and a pound of food, it was not an issue.Jun 14, 2013 at 11:58 pm #1996836
Thanks John and George. I'm leaning towards John's advice that you don't ALWAYS have to carry a heavier pack for a heavier load. It seems like the consensus so far is that, if 25-30 lbs is the fully loaded day-1 pack weight that the Jam will suffice and it's not necessary to spring for a different pack.
Would love to hear back if people agree/disagree with that sentiment
