well i've been wondering how the hell the waist belt attached.i just went upstairs and really checked mine out and i finally found it.

its not the middle piece you circled.if you look at the black material on both sides of the piece you circled,right where the black ends on both sides is where it is.

see where the bottom section of the shoulder straps connect to the pack?,right around where the SR buckles are?

that opens up at both ends and has velcro in it.

other than that they dont know what they're talking about.it definitely comes with a sternum strap and not a waist belt unless things changed in the last month.the waist belt is sold separately on their site for around $33.00

i think they got it backwards.

if you talk to them again ask them if the 3-day is discontinued.

other than that........BUY IT!!!!
