if you look in the back of paragear, right after were the canopy order forms are, it has pack volumes of almost every canopy out there(or at least the ones they sell) but sense i have one right in front of me, the pack volume(acording to sandy reid) is 296 cubic inches. the thing is, every canopy is different. like one batch of material may be thicker, or thiner that the other batch. it may of been really humid the day the pack volumes were taken, or it could of been really dry the day they were taken. these all effect the pack volume. so pack volumes are taken knowing that every canopy is different, so they are just a reference, not exact. another factor is how good is your rigger. not like weather it will work or not good, but can he or she make things very tight and neat. this also effects how it goes in the rig.

296 cu"

[Hooknswoop 19]

According to PD, 314 cu in with polyester/Dacron(which is what I have almost all PD's lined w/). 296 cu in w/ microline. Variations of 10% or more are common due to temperature, humidity, material tolerances, and packing technique.

Also recognize that there are various people producing volume numbers that may or may not be relative to the PIA test method and it's results. Jump Shack has a different testing apparatus, George Galloway uses it differently, and it greatly depends on the operator.

We just had a discussion last weekeend on trying to modify the PIA test method to one less subjective and more acceptable to the industry. Determining container volumes are subjective also.

The BEST way (agreed by all at the PIA meeting) of determining if a particular reserve will fit in particular container size is to call the container manufacturer or talk to an experienced rigger who services similar systems. The "real world" of try it to find out if it fits is right now the only way to be sure. If you try to use Precesion's number, PD's number, and a container volume you may or may not end up with a system that fits. PIA is trying to address this in their technical committee.

Only trust volume numbers published by container manufacturers.
