Removed 3D mesh on my 2010 golite jam

Interesting. How much does it weigh now? Do you miss the mesh back?

I've been doing the reverse with mine (adding weight). I cut off the excess length of straps of course, and the hydration sleeve and replaced the drawcord with gutted GloWire. But I added a two piece section of Z-Lite Sol in the framesheet sleeve along with the stock sheet (very stiff on my version). I put the Z-lite behind the mesh section to increase void space and airflow as I get massive swamp back.

Mine still weighs in at 1 lbs 14.4 oz all said and done.

It weighs 1 lb 3 oz. without 3D mesh or hipbelt. The mesh only weighed 2 oz. but it was the feeing of the mesh I didn't like. I sometimes miss the hipbelt, but the freedom of movement for my hips is nice.

I like your zlite addition. When I add the oxford nylon, I'll still have the pad pocket. I've thought about putting a klymit airbeam for rigidity, padding and backcooling.

I just think a fabric backpanel will be more comfortable than the 3D Mesh. The back is gonna get sweaty, its just I think that back panel absorbs and holds the moisture where a moisture repellent fabric will just have it evaporate off.

So I finally was able to convince my wife to sew on a piece of black oxford nylon in the place where I had cut out the 3D mesh on the back of my 2010 golite jam. The task was very tricky but my wife is an excellent seamstress. Someday I hope to acquire such skill. I have other golite packs I was thinking of doing this to as well but it wasn't as easy to sew the fabric in and flip the pack inside out for clean seams. I decided to keep the mesh on my other golite packs. As you can see at the top near the shoulder straps there is a gap. I still need to finish that off, possibly hand sew.
