Howdy,

Any ULA Circuit owners out there willing/able to measure the body dimensions of their pack? Looking for width/height/depth of main bag. Also wouldn't mind knowing the length of the extension collar. Thanks in advance!

I give them to you in inches so that I can be a bit sloppy...
Standing the pack up , it is 20" high or 32" including the collar (of course not all of that is usable, you lose about 4" when you roll it up..)
Pulling the fabric outward it is 18" wide.
Once filled the diameter is about 11"

BTW, that is a medium size. The difference between my aprox 20" height and the 24" reported by Martin is how I measured the pack standing up, that is accounting for some deph.

My medium is 24" from bottom of belt to the top of the pack hoop. Before extension collar, etc.

circumference at the very top of the extension collar is about 38" (19" wide laid flat) The pack actually tapers toward the bottom, it is larger up top. Hard to measure accurately.

The bottom of course is also tapered toward your butt from the mesh, it slopes down. Im sure Brian had a good reason for this, but it is aggravating sometimes that it wont stand up while packing.

Thanks fellas. Anyone care to comment on wide the side "walls" of the pack body are?

dunno, my guess would be 12X7 perimeter, that gives you the 19" width of fabric when laid flat.(7+12). Not sure what the taper size would be.

Are you thinking of a bear canister ?

or better still ask the specific question, that is "will the Circuit..."
