The transpack BC harness like a full BC, but with no inflating bag.  It 
contains shoulder straps (where D-rings are attached at fixed location) and 
a waist strap.  It is similar to the design of the Zeagle exept that the 
shoulder strap reach the back of the harness instead of attaching the waist 
strap in front.  Dive-Rite claims that the weight of the tank is suported 
much better this way.

You can install three different air cells (the inflating bags) on the 
harness:

1. The Travelpac air cell is good for warm-water diving using standard size 
single cylinder.  It has 30 pounds of lift.

2.  The standard cell has a lifting capacity of 45 pounds.  Its shape is 
similar to the Wings.  It is able to support high-capacity single cylinder 
and lightweight doubles.

3.  The Super Wings is designed for doubles users.  There are two seperate 
bladders and inflaters.  Each of the bags has a capacity of 85 pounds. 
  Special elasticized gussets compress the Super Wings to their smallest 
possible cross section when not inflated.  Contrary to the OMS BC, the 
elastic bands are not covering the BC, but they are squeezing the outer 
shell (made of heavy-duty Cordura) on the inner shell (the inner shell 
contains the two inflatable bags).   One inflater comes on each shoulder. 
 As well, there is one quick-dump and overpressure valve on each side of the 
BC

Another thing to note is that  the harness has eight 1.5 inch SS D-rings 
(four on each side) and three 1 inch D-ring on each side of the back 
(no-plate).  These small D-rings would allow to attach accessories like the 
power-pack of the dive light.

The transpac is entirely soft.  There is no back plate.

As I said earlier, the standard cell and the Super Wings are installable on 
the Dive-Rite common back-plate.

I heard that prototypes are presently in circulation.  A production version 
of the BC should be available at the beginning of next year (february?)

I did not try the BC, I simply received documentation.  I should have the 
prototype in my hands soon.  I do not remember what the cost will be, but I 
noted that it was higher than the cost of the Wings system (this is not the 
same product as well).
