Re: Re: GoLite Jam2 Functionality Question on 07/23/2009 11:14:17 MDT Print View

I turned my Jam2 inside out last night....it was very easy to do. I'm going to use a seam ripper on the two long side seams of the hydration sleeve, but I might cut it along the bottom because that seam is really in tight with other very critical seams which I don't want to damage.

How easy was it to swap the drawcord for Spectra?

I'm hoping to shorten the straps, but I really like how they are doubled back right now. This prevents you from accidentally pulling the strap all the way through the buckle. Did you fold yours and restitch them when you cut them? Or did you just use super glue?

Very easy to swap drawcord--just tie on and pull through. Frankly, not much weight savings at all... Stock straps have about an extra foot of strap; I left about 4 or 5 inches and just melted the ends, but didn't bother folding the new ends back. You could, and it would be simple. I also shortened the hipbelt webbing (way too long) and load lifter straps (an extra ? inches each). I was going to cut off the water bottle pockets on the outside, but they're pretty darn handy, so they stay.

How well did the melting work for the strap ends? Does it look ghetto? Would you recommend this over super glue?

I want to start mod'ing my Jam2 but my scale is in the mail right now. I could just keep all the bits to figure out the original weight at a later date...hmm...

Hi Dan,

It's pretty easy to do on a gas burner. Just make your cut and before it begins to fray, bring the cut edge against the flame from the side, working it a little at a time as you watch the nylon melt and fuse.

It's a little tougher with wide webbing than narrow, but practice with your discarded end to get the hang of it and you'll probably find you're getting "factory fresh" results.

You don't need no stinking glue :-)

Cheers,

Rick

p.s. I used my new Jam2 for the first time last weekend. What a comfy pack it is for a frameless.

I find a long stick lighter works great for this.
I use to use a hot nail to cut the strapping but it was a hassle to keep the nail hot (I used a plumbers torch).
Now a use a sharp pair of scissors and the long stick lighter.

Dan, I just want to confirm your suspician on the bottom seam being critical. I removed my hydration sleeve by seam ripping all 3 seams. It went fine until I got to the bottom seam. It holds the entire bottom together. It was not easy to get it back together...so yes just cut the sleeve at that point.

BTW, I got my Jam2 (08 version) down to 16.75 oz while still keeping the foam back pad and pocket. I cut down the straps, removed the hydration sleeve, removed the strenum strap and cut off the belt.

I kept the foam pad as it helps greatly when using the Jam2 as a day pack. I use the compactor system and sometimes just store my day items in the back pocket.

I just finished my first round of modifications. First, I removed the hydration bladder. It was easy. I used a razor blade and a multi-tool knife serrated blade. I started in the middle of one of the long sides and cut a few stiches with the serrated multi-tool blade. Once I had a few stiches out, it was easy. You could kinda pull the stitches out from then on, you just had to cut off the string as it was getting too long every 5-10 stitches. I used the razor blade on the corners to get into the crack between the bladder fabric and the backpanel. Everything went smooth and after 10 minutes all I had left to do was the bottom edge. I didn't want to mess with this seam, so I just used my razor blade to cut the bladder fabric off as low as I could, and then cut off any dangling threads and called it a win. I'm excited for my scale to arrive so I can weigh this beast and see how many grams I've shaved off.

Next up was some strap cutting. I didn't want to cut the roll top strap or the side compression straps yet because I really need to get the pack fully loaded before I have an idea of how much extra strap I have. I might want to use the side compression straps joined to one another to hold a ridgerest on the back of the pack. If you were only going to use the side compression straps as compression straps, you could cut off a whole lot. Probably a foot.

The straps I did cut as the sterum strap, the two shoulder straps and the waist strap. I cut off 3.5", 6" x 2 and 8" x 2 respectively. Looking at the scraps, I've got a decent pile here. It could weigh an ounce. I'm guessing the strap cutting shaved off an ounce and the hydration bladder 1 to 1.5oz. I really have no idea though. Hopefully my scale gets here soon.

Oh and the melting the ends trick was awesome. It was very easy to do and gave very satisfying results. I love it. I also really like how neat my packs looks when I wear it and there isn't straps dangling everywhere. I would do this mod purely for aesthetics alone. Now I just need to get those side compression straps and roll top strap cut. I also am considering removing one of the 'organizer pockets' inside the hip pockets. I can imagine using one of these for my keys, but I don't know why I'd need two. None of my other packs even have these and there are very few things I carry that are small enough to even fit in here. On the flip side, I doubt they weigh much though. Probably 1/10th of whatever the bladder weighs.

I thought those 'organizer pockets' inside the waist belt pockets were a stroke of genius! I didn't know they were in there when I ordered my pack but I was pleased they were. Like you say they hold keys perfectly in one side and they hold my lip balm and 1oz sunscreen in the other. These little items were always getting lost under Honey Stingers, Snickers and gloves in my old packs.

I've been modding along behind you. Cut the bladder sleeve out and cut the straps down. Yeah, it's only grams saved but it sure looks neater.

Weights on 07/30/2009 11:46:13 MDT Print View

I got my new scale in the mail last night so I could finally evalutate my modifications. The accuracy of the scale is appearing very good, despite being only $3 on eBay. A bunch of my gear that I weighed on an expensive scale at work last summer weighed exactly the same (to the nearest gram) on this new scale. Nothing was off by more than a gram which is remarkable.

To refresh you, I have removed the hydration bladder and cut the main waist straps, sterum strap and the shoulder straps. The bits of strap I have cut off weigh a total of 25 grams. The waist belt straps were the bulk of that weight since they are much larger straps. I go into detail in a previous post, but I think I cut off about 5-6" off most of the straps. By cutting the compression straps and roll top strap I could probably shave off another 10g. I'll likely do that at some point. I could also shave off more weight with more aggresive trimming, but I want to leave a couple inches of buffer for times I'm wearing more clothes or when someone else might be using the pack.

The hydration bladder sleeve and hook that I removed weighed 28 grams (exactly 1 ounce).

My pack now weighs 699g. The intial weight spec'd on GoLite's website is 753g and my scraps account for 53g, so in my packs original form, it weighed 752g. Kudos to GoLite for being so darn accurate with their weights.

Today I weighed the piece the foam used in the backpanel at 34g (1.2oz). If you were sure you never want to use this, you could also cut out the sleeve it seems and probably shave off another ounce.

I'm guessing here, but the hipbelt pockets have got to weigh 1 ounce each. So if you really wanted to shave weight you could shave off atleast 2oz here.

I really don't understand all this hacking on a perfectly good pack, just the ways it is? Why not just purchase a lighter weight pack?

I'll probably never use the hyd. sleeve on my Jam2's. Yeah, I got a medium now, and a large on the way. But, I don't feel the need to remove it, to save 2oz or whatever?

No way would I ever hack off hip-belt pockets, as they're way to useful.
Although, they don't look like they will be very water resistant, and I'll probably have to resort to using pint size ziplock bags to line the pockets?

JAM2 & scizzors on 08/03/2009 17:07:17 MDT Print View

The reason to cut off stuff is to make the pack lighter.

I have a 3.7 oz gossamer gear pack, and I managed to cut some stuff off that too!! Got it down to 3.4 oz!!!

@ Michael: "I really don't understand all this hacking on a perfectly good pack, just the ways it is? Why not just purchase a lighter weight pack?"

The Jam2 is starting to have a lot of features....some of them nice and some of them useless to some owners. It's nice to start with these features and then cut off the ones you don't need, instead of getting a pack with none of these features.

Personally, I like the hip pockets a lot so I'm keeping those, but the hydration sleeve and extra straps can go for sure. I've shaved off atleast 2 oz now, which might not sound like a lot but it gives me the option of either having a 2oz lighter pack, or adding 2oz of luxuries. For example, I can now take my Jam and a big fat cigar for the same weight as you take just your Jam.

@ Mike C: "I just cut 6 ounces off"

Care to go into more detail? I imagine you cut out the hydration sleeve (1oz), removed the foam in the back (1oz), cuz the straps (1-2oz) and what else? Did you remove the sterum strap? Waist pockets?

7 oz off the JAM 2 on 08/04/2009 12:18:01 MDT Print View

NIXED with scissor:
================

- ice axe loops

- side compression straps

- I cut off the top inch of fabric, where the draw cord was sewn over. It's gone. I used a lighter and seared the edge of the fabric. I poked holes and threaded a teeny-weeny string (masons line) like a old navy sea-bag.

- shortened every strap as short as I could get away with.

- Cut out the pocket inside that held the foam pad (this includes the water bladder holder.

- the pad is gone

- the dorky little key holder

- I removed the BIG sternum strap and replaced it with tiny webbing and tiny fastex (I used the side compression strap webbing and fastex)

- I removed the BIG waist strap and replaced it with tiny webbing and tiny fastex (I used the side compression strap webbing and fastex)

- I kept the side pockets on the hip padding

- I kept the side pockets on the body of the pack

(it totals 7 oz exactly when I way my pile of detritus)

May as well cut out the zipper from the front pocket too. You can sew in a small piece of velcro for a closure.Heck, cut the front pocket out completely.

I have cut the zippered pocket off completely on another pack JAM, and I like it.
