Ryan Collinswrote a review of Black Diamond Solution Guide Harness - Men's on April 11, 2019
Familiarity: I've put it through the wringer
This rig takes the best features of a number of BD harnesses and combines them into one super comfortable, burly and featured trad harness.
Comfortable - Short of a wall harness this is the most comfortable harness in the BD line.
Gear Loops - This harness has more than enough storage capacity. The front loops are 25% bigger than the standard BD gear loops (same size front loops as a Chaos Harness) and it has the accessory gear loop on the back.
Burly - the fabric on exterior of the harness is by far the burliest fabric I've ever used on a BD harness. I've ruined plenty of harnesses in the desert and this one is 2 desert seasons in and still going strong.
The webbing running from the lower tie in point to the leg loops isn't stacked like the Solution which helps prevent the wear point that the Chaos & Solution harnesses had if you like to stick your leg in a nice #5 or #6 crack.
So go stuff your self in that OW/Chimney, bring that extra cam and enjoy your day in comfort.
