Backpack Jam in 2009 was supposed to be a continuation of the historical model introduced by Golite Jam many years ago. It is slightly larger than the progenitor because of size L is 51 liters (instead of the earlier 45L). This was partly due to a larger pocket on the front plus initially 3 to 6 liters.
was enlarged a little space of the main chamber and the size of the side pockets (they utilize the kind of flexible translucent fabric (lycra) instead of the previous grid). 
upper edges of the side pockets are angled so that we can successfully use them did not removing the backpack. 
Besides capacity backpack, I am cultivating a tradition: as the archetype of functional additives is more than you can in this backpack wish. As part of the backpack adjacent to the back we have a breathable mesh padding (previously we had at this point nylon with Dyneema). 
Inside we installed the foam panel (the panel is removable). Corrected in relation to the original backpack straps are shaped (or as for women and for men) and covered with breathable mesh. Of course, we are comfortable, adjustable strap at the height of the breast, and clasp fastening it was equipped with an integrated whistle.
Backpack also features a lap shoulder strap buckle fastened with a new shape. In general, this backpack buckles Golite'a a new quality. Sling was partially padded mesh for comfort. 
Manufacturer heard my prayers;) and shoulder strap he made two fairly capacious zippered pockets. 
pockets do not guarantee a watertight because they are from the same material as the side pockets (a type of dense grid lycrowatej). Allow conceal items such as handheld camera, phone or candy bar. 
inside pockets have compartments for smaller items such as keys, flashlight, etc. Even for the same allowance of pocket Jam 2009 is a big plus for me. Inside the main chamber we have a flexible pocket for a bottle of (up to about 3 liters). Inside, we even hang hook allows a skin smaller size of the inside pocket.
output tube from the skin of both sides are back but their new shape at 100% will have just the bag of water during rainfall. 
Main compartment is locked with a rolled crimped rope funnel with stopper and tape compressible with buckle. This solution we already know from the previous cavity, and nothing in this regard has not changed. Tape allows przytroczenie mats or snowshoeing at the top of the backpack. 
Speaking troczenia - finally lived to side compression straps to such lengths to actually be there was something in your backpack przytroczyć. Present their length ensures trouble-free full-length foam pad troczenie or two-person tent. Side compression strap can be extended to such a degree that combined with the buckles on the opposite side of the backpack by compressing in this way the whole backpack. 
front pocket is closed with a zipper flap as it was in the original. You can see the manufacturer stopped believing castles mounted in a waterproof, Jamie 2, 2008. 
Besides compression straps on the side of the backpack is used, a new system called ComPACKtor. At the bottom of the backpack have two plastic buckles on the opposite side and two loops capable of significantly reducing the volume of the backpack when we do not need it. Then with a big sack gets us to a neat backpack designed for one-day escapade. It might seem like a gimmick but no matter this way, compression shifts the contents of the backpack, and thus also their weight closer to the body. Outside the backpack was located two loops for attaching ice axes or trekking poles.
with other important things I should add that changed the fabric of the backpack is made. Today it is a fabric previously used in a backpack Golite Pinnacle called Dyneema-X (X is associated with the way it cross visible dyneema). Is the traditional ripstop nylon with Dyneema, and that there are some differences in functionality can not say. Spawaia impression material is thicker than that which was used in my Jamie (first generation) but maybe it's just an impression. 
weight in the backpack size L is 762 grams. Weight declared by the manufacturer is less than about 9 grams so it's a pretty nice result. Foam stiffening back weighs 39 grams so after it is removed we get a backpack weighing 723 grams. I am the first generation after odchudzeniu weighs 200 grams less but they all have their weigh stuff;) Overall backpack makes a very good impression. There is certainly a very thoughtful design creates a large flexibility in packaging and arranging equipment. Also leaves freedom in the weight loss of weight. As time goes by will complement the information on the utility of this backpack.
